# FileSize Sort Script (FS3) by Security XIII; 15.03.2013
# Another script name: Find & Sort Out Important Files After HDD Recovery (with photorec)
# This script arranges all files in current and recursive folders into the following scheme:
# One folder for each filesize range:
# less than 10kb, 10kb to 50kb, 50kb to 100kb, 100kb to 300kb,
# 300kb to 500kb, 500kb to 1mb, 1mb to 3mb, and larger than 3 mb.
# This is quite comfortable to find important files after HDD recovery.
# Just put the file in the folder you want it to work, do chmod +x sort.sh, run like "./sort.sh"
# Note: it will create separate folders inside each folder you have under its (script) "." location
# Note 2: it will also name this folders with postfix of $i, which is just counter
