[Tutor] Getting "file sizes"

[Andrew Fant]

Is there a reason you couldn't use glob() to generate a list of all the 
files in the
directory that match a wildcard pattern and then make a for loop over the 
list to call getsize() and grab the results?

I could be completely out of my depth here, but I did something like this 
once to grab ID3 tags from a bunch of scattered mp3 files.
