It’s time for some more significant updates to the Windows and Android versions of DiskDigger! Here is what’s new in the latest version of DiskDigger for Windows:

• Revamped and improved support for scanning disk images. Ideal for professional forensic analysis, as well as personal recovery of disk images, all of these types of disk images are supported:
  • E01 and EWF images (Expert Witness Format) saved by EnCase and various other tools. If the image is broken into multiple segments (E01, E02, etc.), just open the E01 segment and DiskDigger will detect the other segments automatically, as long as they are in the same folder.
  • VMDK images, used by VMware.
  • VDI images, used by VirtualBox.
  • VHD images, used by Microsoft VirtualPC.
  • Plain ‘dd’ raw images.
• Open any of the above disk image types by launching DiskDigger and clicking the Advanced tab, where you should see the option to scan a disk image. Once you select the image file, the type of the image will be detected automatically.
• E01 files themselves can now be recovered in «dig deeper» mode.
• Support for recovering FLIF (Free Lossless Image Format) images.
• Improved support for recovering .TAR.GZ archives.

The Android version of the DiskDigger app now has the following updates:

• Improved support and compatibility with Android Oreo.
• Fixed some potential issues when saving recoverable files to an external SD card. Previously it was possible to see «access denied» errors when saving files to an SD card, which was due to incorrect usage of Android’s SAF (Storage Access Framework).
• Improved ability to permanently delete individual files from Basic Scan results. It’s currently not possible to delete files from a Full (rooted) scan, but this is planned for a future update.

This month brings several exciting new features and enhancements to DiskDigger for Windows:

• Support for recovering FITS images (Flexible Image Transport System) in «Dig Deeper» mode. FITS is the image format used in astronomy, and is endorsed by NASA and the International Astronomical Union. This type of file can contain many different types of data besides actual images, and DiskDigger can now recover all of them.
• Support for recovering SER videos, which is a video format used in astronomical imaging.
• Support for recovering AAX (Audible Enhanced Audio) files, which is the DRM-protected audio format used by Audible.
• Support for recovering DjVu (.DJVU) documents.
• Improved detection of corrupted partitions on a GUID partition table (GPT).

And of course there are a few minor enhancements to DiskDigger for Android, which include optimized performance on older devices, as well as improvements to Clean Up mode. 

Download DiskDigger today to recover your lost files from any media that your computer can read! Or if you need to recover data from your Android device, find the DiskDigger app on the Google Play Store!

Cleaning up

Along with recovering your files, DiskDigger gives you the ability to delete them permanently, so that they will no longer be recoverable. Next to the «Recover» button you’ll find the «Clean up» button, which will take you to Clean Up mode:

The Cleanup screen is divided into two tabs: «Thumbnail caches» and «Photos.»  This is because a thumbnail cache (a file that contains multiple thumbnails) must be deleted as a whole, which would delete all the thumbnails contained in it.  Therefore the app allows you to examine these thumbnail caches, as well as individual photos, and select which ones you want to delete.

Cleanup Mode is currently available only in the Basic Scan. Making it available in the Full (rooted) scan is quite a bit more complex, and will be available in a future version.

Note: Since the deletion is done at the filesystem level, the contents of the deleted files are not physically wiped from the device’s memory, and may still be recoverable if the device is rooted. In fact, even physical wiping of the files’ contents is unreliable with flash memory, which employs wear-leveling that might redirect the overwritten data to a different physical location.

Wiping free space

Another powerful feature provided by DiskDigger is the ability to wipe the free space on your device’s memory. This is useful for ensuring that your deleted files (which are now considered free space in your device’s memory) will no longer be recoverable, even using tools like DiskDigger.

The «Wipe free space» feature can be accessed directly from the main screen of the DiskDigger app (underneath the selections of Basic Scan and Full Scan). It can also be accessed while performing a Full Scan by tapping the Cleanup button.

Like the «Clean up» feature, the «Wipe free space» feature is still a bit experimental, so you should be aware of some of its caveats and limitations:

• Wiping of free space is done by creating a temporary file and filling it with random data, until it consumes the entire amount of free space on your device. When the temporary file begins to reach the limit of free space, the Android system will usually display a notification that your available space is running out. You should ignore this notification until the wipe process is complete. When it finishes, it will delete the temporary file and free up the remaining space again.
• It is possible that the Android system will stop DiskDigger from being able to write to the temporary file before the memory is completely full. This means that there is a possibility that not all of the free space will be wiped, and some deleted data might still be recoverable. You can always re-run DiskDigger and scan your device’s memory to ensure whether the wipe was successful.
• The wiping is done only on the internal memory of the device. The ability to wipe an external SD card will be added in a future version.
• It’s important to note that because the wiping is done by overwriting all the free space, it means that the process inflicts a significant amount of wear on the device’s memory. This can potentially shorten the life span of the memory, and should be performed sparingly, and only when necessary.

Как работает Diskdigger Pro?

Вы знаете, в телефонах Android нет корзины, как на ПК, поэтому иногда мы по ошибке удаляем нужную фотографию или важный файл и ничего не можем сделать, кроме как желать, чтобы этого никогда не было. Понимая эту ситуацию пользователей, разработчик Defiant Technologies придумал Diskdigger, приложение, которое позволяет находить и восстанавливать удаленные файлы. Итак, как это работает?

После удаления файла на вашем Android-телефоне этот файл не удаляется полностью из системы. Он по-прежнему сохраняется на жестком диске как удаленный файл и не отображается при доступе к хранилищу устройства. Diskdigger дает вам второй шанс. Он сканирует все файлы в вашей системе, включая удаленные. После успешного сканирования отображаются все удаленные файлы, вы можете восстановить их до исходного состояния.

Выберите «Сканировать», чтобы приложение начало сканирование всего жесткого диска. Конечно, вы получите тысячи результатов с множеством системных файлов и ненужных файлов. Чтобы помочь пользователям быстро найти нужный файл, приложение позволяет вам выбрать тип файла, минимальный размер файла. Кроме того, вы также можете разделить память для более быстрого сканирования, в котором внутренняя память устройства обычно отображается как «/ data», а SD-карта отображается как «/ mnt / sdcard».

Для работы приложения нужен root?

Diskdigger Pro требует, чтобы ваш телефон Android был рутирован для поиска удаленных файлов на диске. Если ваш телефон не рутирован, приложение все равно может работать, но не на 100% эффективно. В частности, приложение позволяет вам находить и восстанавливать файлы определенных типов, и нет гарантии, что вы его найдете. Вы также можете найти только файлы с фотографиями, но не видео.

В чем разница между Diskdigger Pro и бесплатной версией?

Diskdigger Pro продается в Google Play за 170 рублей, предоставляя вам гораздо более мощные функции, чем бесплатная версия. В версии Pro можно копать глубже и детальнее, чем в бесплатной версии. В частности, большинство пользователей используют бесплатную версию для поиска фотографий и видео. Если вы хотите восстановить другие типы файлов или большой тип файлов, вы не можете сделать это с помощью бесплатной версии.

Платная версия приложение позволяет искать и восстанавливать файлы любого типа через FTP, если ваш телефон рутирован. Кроме того, приложение также предоставляет возможность очищать свободное место на жестком диске, помогая вашему устройству иметь больше памяти и работать более плавно.

Куда сохранится файл после восстановления?

Есть три способа сохранить файл после восстановления, включая сохранение в приложении, сохранение в локальном хранилище и сохранение на FTP-сервере. Вы можете сохранить в приложении, чтобы быстро сохранять данные в таких приложениях, как Google Диск, Dropbox, Gmail. Если вы хотите сохранить его на FTP-сервере, вам необходимо войти в систему, чтобы синхронизировать данные в облаке.

Очистка диска

Это особенность эксклюзивной Pro-версии. Как упоминалось выше, Diskdigger Pro может полностью удалять файлы из системы, что означает, что вы больше не можете их восстановить. Это означает, что вы не можете найти и восстановить эти данные, даже если вы используете Diskdigger Pro или подобное приложение.

It’s time for another important update to DiskDigger for Windows! Here is what’s new in the latest version:

• Improved accuracy and efficiency of detecting certain raw camera formats, including Nikon (NEF) and Canon (.CR2).
• Revamped and improved recovery of .MP3 audio files. Will now recover a wider range of .MP3 files from different sources and devices.
• Added support for recovering .AAC audio files.
• Added an advanced option to perform a more thorough search for .MP3 or .AAC audio. After selecting «Dig deeper» mode (when selecting the types of files to search for), go to the Advanced tab and select the «Extra deep MP3 search» option. This option is still experimental and is not selected by default, since it can produce false positives.
• Added another advanced option to start the scan from a specific sector on the disk. When selecting the types of files to scan, go to the Advanced tab and enter the custom sector number in the «Starting sector to search from» text box.

Download DiskDigger for Windows now to search any of your hard drives, USB drives, or memory cards for deleted files!

The latest update to DiskDigger for Windows improves upon its general performance, as well as these specific enhancements:

• Improved handling of compressed files in NTFS filesystems. When your disk is formatted with NTFS, individual files can be compressed (using a variation of LZ77) to conserve disk space. When scanning in «Dig Deep» mode, DiskDigger automatically and transparently decompresses these files, so that they can be recovered in their original state.
• Improved handling of system-compressed files in NTFS.  Windows 10, as part of its background operation, searches for certain files that are seldom used and automatically compresses them. This is different from the «standard» compression that can be applied to NTFS files. This compression is done by creating an alternate data stream (with a reparse point) called «WofCompressedData» and filling it with the compressed data, which is compressed with the Xpress or LZX algorithms. DiskDigger handles all of these cases, and automatically recovers these types of files in uncompressed form.
• Added support for recovering Quicken data files (.QDF) in «Dig Deeper» mode.
• Improved efficiency of recovering executable (EXE and DLL) files.
• Fixed some possible stability issues when previewing WAV audio files.

In other news, DiskDigger for Android also received an update, with improvements to its «Wipe free space» function, which is now faster and more effective than before.

The latest version of DiskDigger for Windows is easier to use and more powerful than ever! Along with an improved interface with better instructions and visual cues, DiskDigger comes with these great new features:

• In «dig deep» mode, there is now a new option to show files that were likely emptied from the Recycle Bin. If you’ve accidentally emptied the Recycle Bin, this will make it easier to find the files that were in it.
• In «dig deep» mode, recoverable files are now sorted by last-accessed time, so that files that were deleted more recently are likely to be near the top of the list. (You may still sort the files by name, size, or date by clicking on the corresponding column headers.)
• General performance improvements when filtering recoverable files in «dig deep» mode.
• Added support for recovering Lytro raw images (.LFP).
• Improved detection of 3D .MPO images.
• DiskDigger now requires version 4.0 of the .NET Framework. This means that it will run on Windows 10, Windows 8.1, and Windows 8 without needing any additional components. For running on Windows 7, Windows Vista, or Windows XP, you may need to install .NET 4.0 if it’s not already installed on your system.
• Experimental support for running on Mac OS X!

Download DiskDigger for Windows now!

Saving locally

The second option allows you to save the recoverable files back to the local device (to the internal memory or SD card of the same device from which the files are being recovered).

Saving on Android 5 (Lollipop) and above

This will take you to the standard Android folder picker that you can use to select the folder into which the files will be saved. Unfortunately the standard picker can be a bit difficult to use for the first time. If you see an empty screen with an «Open from» title like in the screenshots below, then follow these steps:

• Swipe away the «Open from» panel to the left.
• Tap the overflow menu (three dots) in the top right corner, and select «Show SD card» or «Show internal memory».
• Tap the navigation menu (three lines in the top left corner, and you should now be able to pick the SD card or Internal memory, and navigate to the exact location where you want to save the files.

Saving on Android 4.4 (Kitkat) and below

You will be prompted to select the directory where the file(s) will be saved. The directory defaults to the location of the memory card on your device (most commonly «»). The directory picker allows you to navigate through the directory structure of your device:

Important note: You should use this method only if you can save the files onto a different partition than the one from which the files are recovered. For example, if you’re recovering files from internal memory, you should save the files onto an external SD card (not internal memory).  It is not recommended to save the files onto the same partition from which they were recovered, because that would risk permanently overwriting the very same files that are being recovered!  You should attempt to use one of the other methods of saving the files (save to another app or FTP upload) before resorting to saving locally.

Time for another great update to DiskDigger for Android! Over the last few months, more and more users have requested the ability to delete the photos and other files that are found by DiskDigger, so that they can no longer be recovered by anyone else. This update makes a significant step in that direction:

After completing the scan of your device, the app now offers you the ability to enter Cleanup Mode, accessible by tapping the «Clean up» button, where you can select the items you’d like to delete, and remove them permanently.

This feature is still very new and a bit experimental, so there are a few points to keep in mind when using it:

• Cleanup Mode is currently available only in the Basic Scan. Making it available in the Full (rooted) scan is quite a bit more complex, and will be available in a future version.
• The Cleanup screen is divided into two tabs: «Thumbnail caches» and «Photos.»  This is because a thumbnail cache (a file that contains multiple thumbnails) must be deleted as a whole, which would delete all the thumbnails contained in it.  Therefore the app allows you to examine these thumbnail caches, as well as individual photos, and select which ones you want to delete.
• Since the deletion is done at the filesystem level, the contents of the deleted files are not physically wiped from the device’s memory, and may still be recoverable if the device is rooted. In fact, even physical wiping of the files’ contents is unreliable with flash memory, which employs wear-leveling that might redirect the overwritten data to a different physical location.

In the near future, look for further enhancements and updates to the Cleanup feature. And as always, DiskDigger for Android and DiskDigger for Windows are still the best choice for your data recovery needs.

Digging deeper

The «dig deeper» mode causes DiskDigger to become a powerful data carver, and carve out whatever files it can find on the disk, independent of the file system.  Data carving refers to physically scanning every single sector on the disk, and looking for traces of known file types.

This mode also has some advantages and disadvantages. The main advantage is that it’s independent of the file system that’s on the disk, so the disk can be formatted as FAT, NTFS, HFS, ext2, or anything else; it doesn’t matter. DiskDigger scans «underneath» the file system, which gives it an additional advantage of being able to scan any free space on the disk outside of the file system, which the «dig deep» mode cannot do.

The main disadvantage of digging deeper is the time it takes to complete the scan. If you’re scanning a memory card or USB drive, it shouldn’t be too bad, but if you’re scanning an entire hard drive, be prepared for a several-hour job.  Of course the burden of the time spent on the scan is subjective, and depends on the value of the files you’re trying to recover.

Another disadvantage of this mode is that only a limited number of file types can be recovered. Since we’re not aware of the file system, we have no way of knowing what types of files are present, so the only thing we have to go on are the actual bytes that we see on the disk. This means that DiskDigger has to be aware of the structure of the types of files we need to recover, and search for patterns of bytes specific to each file format.  Fortunately, DiskDigger supports a fairly wide variety of file types which should cover most cases.

The only other disadvantage of this approach is that it’s not possible to recover files that have been fragmented by the file system. Since it’s not aware of the file system, DiskDigger has no way of knowing whether or not a certain file has been fragmented.  So, technically, when digging deeper, DiskDigger will only recover the first fragment of a file. Most files consist of a single fragment anyway, but in some cases, the file system will choose to split a file into two or more fragments. A rule of thumb is:  the larger a file is, the more likely it is that it’s been fragmented.

Особенности приложения

Часто ли вам приходилось беситься из-за того, что вы по чистой случайности удалили нужный вам файл на смартфоне. Теперь вам не придется злиться, ведь любые удаленные данные можно легко восстановить. Для этого вам потребуется всего лишь скачать DiskDigger Pro на Андроид. Эта простая программа позволяет работать даже с системными файлами, легко удалять или восстанавливать данные из памяти мобильного устройства.
