Tim Peters added the comment: All versions of cmd.exe want backslashes in paths for the commands implemented _by_ cmd.exe - those interpret a forward slash as indicating an option. For example, here on Win10 Pro:
C:\WINDOWS\system32>dir c:\Windows\System32\xwreg.dll Volume in drive C is OS Volume Serial Number is 5E8B-CFAC Directory of c:\Windows\System32 10/30/2015 02:17 AM 120,320 xwreg.dll 1 File(s) 120,320 bytes 0 Dir(s) 2,880,244,813,824 bytes free `dir` is implemented by cmd.exe, so that example doesn't work with forward slashes: C:\WINDOWS\system32>dir c:/Windows/System32/xwreg.dll Parameter format not correct - "Windows". ---------- nosy: +tim.peters _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27045> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
