Shuffled File Set Renamer

This program randomly renames all files in a folder into shuffled Sets like these:

• asdasd_01.mp4
• asdasd_02.mp4
• asdasd_03.mp4
• asdasd_04.mp4
• hjkhjk_01.mp4
• hjkhjk_02.mp4
• hjkhjk_03.mp4
• hjkhjk_04.mp4
• werwer_01.mp4
• werwer_02.mp4
• werwer_03.mp4
• werwer_04.mp4

Original order of files has been jumbled and shuffled in the process.

Why? Purpose: If you're uploading files somewhere and you want their order to be randomized instead of alphabetically ordered, this can help.

The sets are useful if you want to split your collection of... say 120 files into sets of 20 files, so you get 6 albums.
