A little GUI tool to analyze the content of usb drives
« on: July 24, 2015, 07:38:09 PM »
This will display all of your mounted usb drives, then you select one.
The script will analyze the contents of the drive and display info about file types and size that file type takes on a drive.
I took some code from "makethumb" script and modified it for my needs.
As you can see it tell me how much space are images taking on this usb drive.

Code: [Select]
