help with file path exceeding 255 characters
I have trouble of obtaining the file size of a file because the fullpath exceeds 255 characters. I get this message with os.path.getsize(fullpath). fullpath = r"\\LOSSSFS002\NWE_TECHNICAL\05. UK\Schiehallion (204_25a) \Amos&Burke_P559\07. Technical (Subsurface)\06.

I tried using the relative path, but it does not work with the message fname not found. dir = os.path.dirname(fullpath) fname = os.path.basename(fullpath) os.chdir(dir) filesize = os.path.getsize(fname) Is there a walk around of this? -- http://mail.python.org/mailman/listinfo/python-list

Good idea. But subst does not see to work with path that has spaces.
It gives "Incorrect number of parameters"
