TorrentCheck

TorrentCheck is a tool developed by Pleasuredome member blackpudd. It's available as 32-bit and 64-bit binaries for Windows, Linux and MacOS. It has multi-language support.

Because there isn't an official webpage (it was distributed in the defunct Pleasuredome Forum), the 64-bit Windows version can be downloaded from here for now.

What it does
TorrentCheck checks if the files on a computer match a torrent. For every run, a report file is created in  format. The following can be checked:
 * If the files exist
 * If the files' sizes are correct
 * If the torrent's hashes match
 * If there are unneeded files and folders

Additionally, it's able to:
 * Delete or move unneeded files and folders to a user-defined backup folder
 * Attempt to find missing files based only on file sizes
 * "Attempt to fix/rebuild missing files" will scan the backup folder and try to rebuild any missing files from there. Say for example you deleted unneeded files, the names of the files may have just changed and it will move them back with the correct name. Or you can point the backup folder to a new location and TorrentCheck will scan that folder for matching files and copy them.
 * Delete files with wrong size
 * Trim padded files, which is useful to fix files downloaded by some buggy µTorrent versions
 * Show completion percentage (requires SHA-1 file integrity check enabled)
 * View (and save) the list of files and folders of a  file
 * Select which files and folders that are on the computer should be ignored by the 'unneeded' scanner
 * Open the torrent file in default torrent client

Quick Guide
TorrentCheck is pretty simple to use:
 * 1) "File"  &rarr; "Select .torrent file": add the .torrent file
 * 2) "File"  &rarr; "Select torrent directory": select the folder where the contents of the torrent are
 * 3) "Check file integrity (SHA-1)" on the main window can be disabled to only check file sizes, which is much faster
 * 4) Press the large "Check Torrent" button
 * 5) After processing, the resulting text file will be automatically opened with Notepad

Hint
Usually, when you have the wrong file (in other words, a file with wrong hash value), its size is wrong. That's why the file size check is usually enough for checking. Running TorrentCheck with "Check file integrity (SHA-1)" disabled is much faster because it doesn't need to calculate the hash values of all files. If you are changing the files you have to try to match a torrent, keep that setting disabled and run TorrentCheck as many times as needed. After you did all you could do to match the content of the torrent, run TorrentCheck again with that setting enabled.
