"Thumbs.db Viewer 3.6": Frequently Asked Questions

  • FAQ

What is this program's purpose?

"Thumbs.db Viewer 3.6" was written to give the computer user tools to reconstruct Thumbs.db (ehthumbs.db (Windows XP MCE), thumbcache_*.db (Windows Vista, Windows 7, Windows 8, Windows 10) and iconcache_*.db (Windows 8, Windows 10)) database records.

"Thumbs.db Viewer 3.6" allows: displaying Thumbs.db (thumbcache_idx.db, thumbcache_16.db, thumbcache_32.db, thumbcache_48.db, thumbcache_96.db, thumbcache_256.db, thumbcache_768.db, thumbcache_1024.db, thumbcache_1280.db, thumbcache_1920.db, thumbcache_2560.db, thumbcache_sr.db, thumbcache_wide.db, thumbcache_wide_alternate.db, thumbcache_exif.db, thumbcache_custom_stream.db, iconcache_idx.db, iconcache_16.db, iconcache_32.db, iconcache_48.db, iconcache_96.db, iconcache_256.db, iconcache_768.db, iconcache_1024.db, iconcache_1280.db, iconcache_1920.db, iconcache_2560.db, iconcache_sr.db, iconcache_wide.db, iconcache_wide_alternate.db, iconcache_exif.db, iconcache_custom_stream.db) database records as well as the miniature graphics generated in each (with metadata: original file name and timestamp); displaying technical information (headers of files, entries and thumbnails, image details, etc.); collects all the Thumbs.db (thumbcache_idx.db, thumbcache_16.db, thumbcache_32.db, thumbcache_48.db, thumbcache_96.db, thumbcache_256.db, thumbcache_768.db, thumbcache_1024.db, thumbcache_1280.db, thumbcache_1920.db, thumbcache_2560.db, thumbcache_sr.db, thumbcache_wide.db, thumbcache_wide_alternate.db, thumbcache_exif.db, thumbcache_custom_stream.db, iconcache_idx.db, iconcache_16.db, iconcache_32.db, iconcache_48.db, iconcache_96.db, iconcache_256.db, iconcache_768.db, iconcache_1024.db, iconcache_1280.db, iconcache_1920.db, iconcache_2560.db, iconcache_sr.db, iconcache_wide.db, iconcache_wide_alternate.db, iconcache_exif.db, iconcache_custom_stream.db) files in and below the specified folder; searches the Recycle Bin (INFO2 files) for deleted Thumbs.db files; extracts and views all or selected pictures as HTML representations; view with external image viewer any of the original file corresponding to stored in an Thumbs.db (thumbcache_*.db, iconcache_*.db) thumbnail`s metadata (if it exists); view the image in full size or as the best fit for program`s window; rotate images right or left; using a heuristic algorithm, the program can search swap and hibernation files for a JPG graphic files.

Thumbs.db is a hidden system file generated automatically by Windows when you view the contents of a folder in "Thumbnail" or "Filmstrip" view. Thumbs.db contains a copy of each of the tiny preview images generated for image files in that folder so that they load up quickly the next time you browse that folder.

Thumbs.db (thumbcache_*.db, iconcache_*.db) is actually a database of the miniature images that exist in the folder from which they were initiated. The early versions of Thumbs.db files as they appeared in Windows ME and Windows 2000 contained not only the thumbnail image of the parent file, but also the filename, drive letter, and path to that image. Later versions, Windows XP and Windows 2003, store the image and its filename but not the path. In Windows Vista the Thumbs.db file has been replaced by several "thumbcache_xxx.db" files which are now located within the user`s profile. Our program support a thumbcache_*.db files.

Deleting the Thumbs.db file in Windows has no affect on your operating system: the Thumbs.db file is recreated in each folder each time you view thumbnails.

Even though the images have been deleted in the folder they could still exist in the Thumbs.db (thumbcache_*.db) file along with their modification dates.

What is the difference between the free and the commercial (full) versions?

It is demonstrated only the first seven pictures from Thumbs.db (thumbcache_*.db, iconcache_*.db) and from swap file for the free version, but it is reconstructed all of them.

How to install and uninstall the program?

There is no special task to install. Just run self extractable archive.

To uninstall program use UninstallTdv36.exe (Start button | Programs menu | Janusware | ThumbsDb36 | Uninstall ThumbsDb Viewer 3.6).

How the files are deleted?

Our program allows you to shred thumbnail files from your computer. Moving the files to the Recycle Bin only creates an illusion of data destruction. Simply writing over the old files also does not destroy the old information reliably. The hard drive writing head positioning inaccuracy does not completely remove magnetic information on each side of track. Data recovery methods could permit recovery of this information.

This program uses a special method of overwriting files with random byte combinations which makes recovery impossible. This technology conforms to the Peter Gutman method, which makes software and hardware file recovery impossible.
