A release for the Gekihen contest, which is a Coding contest for the PSVita, heres the full details of this release:

Save valuable space on your memory card by shrinking unneeded manuals, language and video files to 0-Byte files.
Game Shrinker automatically searches for manuals, language (text, audio, images) and video files in the game directories and offers you the possibility to shrink them to 0-Byte.

Shrinking files to 0-Byte is usually better supported than completely deleting them and reduces the chance of crashes and getting stuck when the file would usually be accessed by the game. Depending on the game and file, you still cannot shrink every file, though.

Game Shrinker comes with a "Try-A-Dummy"-Feature, which let's you temporary replace a file with a dummy-file. After you tested the game you can then decide to make this change permanent or undo it. (This saves you from having to reinstall the game if you shrinked a file that is obligatory for the the game)
