I am trying to duplicate the functionality of a program called "sizeme" for windows. The purpose for this program is to feed it a file list and it will arrange the files for disk storage.
The goal is to have totally customizable output, ie.:
1. make subdirs like disk01, disk02....disk23 with symbolic links inside.
2. Make an ISO for each disk to be made
3. variable disk sizes
and complain (with list) of files too large for the target media.
I would also like to implement CLI and GUI versions (maybe by switch?).
Here's what I have so far (and I'm sure that a lot could be optimized). As you can see, I did all the easy work
. If you have the skills to assist me, would you kindly?
