Question

Is there a simple way to check in Python if a file system is case insensitive? I’m thinking in particular of file systems like HFS+ (OSX) and NTFS (Windows), where you can access the same file as foo, Foo or FOO, even though the file case is preserved.

Answer 1

import os
import tempfile

# By default mkstemp() creates a file with
# a name that begins with 'tmp' (lowercase)
tmphandle, tmppath = tempfile.mkstemp()
if os.path.exists(tmppath.upper()):
    # Case insensitive.
else:
    # Case sensitive.
