Updated to include size rounding and proper error checking. Worked fine in / on several *nix boxes.

Thanks Dorantor!

You are right, it definitely needs some error handling. Thanks for the patch! I will give this script some more attention, adding error-handling and rounding, and make it available.

Sorry about the formatting, I am just using the Ajax Edit Comments plugin right now. I will try to get a better commenting system in place.

When I tried to use this script it doesn’t works w/o error handling. Small, quick’n'dirty hack solves my problem I leave commented simple example how errors can be handled for any who would like to write it.
You may also note – I added rounding to returned values, so now results are more readable.

[code]
def get_dir_size(dir):
"""
Get the size of the directory passed.
"""
dir_size = 0
for (path, dirs, files) in os.walk(dir):
for file in files:
filename = os.path.join(path, file)
try:
dir_size += os.path.getsize(filename)
except OSError,e:
dir_size += 0 # just do nothing. for now.
# if errno.ENOENT == e.errno: # http://docs.python.org/library/errno.html
# print os.strerror(e.errno) + " (" + e.filename + ")"
return round(dir_size / (1024*1024.0), 2)
[/code]

BTW! You will (possibly) need this:

[code]
import errno
[/code]
