You need to re-think your depth computation. You're using $c for that, but the way I see it that can't be right. You're incrementing $c for each subdirectory within a directory -- not for each level. And you're also setting it back to 1 when you find a file within the directory that's not a subdirectory.

With recursion, the typical model is to increment a depth variable on entry to the function -- not before a recursive call. That way the stack pops it back to its proper value as each recursive call returns.

I'm also not 100% comfortable with a global PARSEDIR. The way you're using it -- getting the entire file list sorted -- you should be okay. But typically, on recursion if you open the same global it will have that global setting on return; i.e., you may return from a recursive call to find PARSEDIR referring to the directory you just processed. I always local these to avoid that (since you can't my a typeglob).
