This is a very handy script!
Here are two additions I found useful. Add them if you like them.
1. Add box for typing or pasting a path from clipboard when browsing for root folder:
change
FileSelectFolder,startfolderto
FileSelectFolder,startfolder,,32. When starting the program, populate the ListView with the folder delempty.exe resides in and all its subfolders.
change
includefolders=0
Returnto
includefolders=0
startfolder=%A_ScriptDir%
Gosub, COUNT
ReturnHere's a request:
When selecting multiple rows in the listview, allow to toggle check/uncheck checkbox for all of them with space (currently only one row gets checked/unchecked). I don't know how to implement that in AutoHotKey myself, but I bet it can be done.
