Just a simple little program which displays some bars which indicate how much space files and subdirectories are taking up in a specified parent directory on your computer. Because of screen space limitations, directories which have lots and lots of files/subdirectories will have all but the largest 30 bundled up into a single bar at the bottom. Not very elegant, I know.
Since I also packaged it all into a .jar, I also made it so that if it takes longer than a minute to scan through the subdirectories, it will ask if you want to stop the program. While the program doesn't have a particularly large amount of overhead, it will keep running unless you stop it somehow, hence this sort of a workaround. Sometimes you have lots of subdirectories in places...
This is one of those "I have an idea for some random program, maybe I should make it" types of programs, I guess?
