Using Python, how can I access a shared folder on windows network?
Use forward slashes to specify the UNC Path:
open('//HOST/share/path/to/file')
(if your Python client code is also running under Windows)
How did you try it? Maybe you are working with \
and omit proper escaping.
Instead of
open('\\HOST\share\path\to\file')
use either Johnsyweb's solution with the /
s, or try one of
open(r'\\HOST\share\path\to\file')
or
open('\\\\HOST\\share\\path\\to\\file')
.
