Incorrect handling of \\?\UNC\ #6

Closed kmarivoe closed 9 years ago

kmarivoe commented 9 years ago

Hi,

I'm trying to use 'ZlpIOHelper.CreateDirectory' on a path with a share name, for example: "\192.168.11.150\Share\data"

the long path representation is: "\?\UNC\192.168.11.150\Share\data"

When I try o run create directory on this, Zlp doesn't detect that this is a share path: SplitFolderPath removes the '\?\UNC\" prefix, which leaves '192.168.11.150\Share\data...", and this is a normal path. As a result I get a directory in the working dir of my application, rooted at '192.168.11.150'.

I'm using ZetaLongPaths 1.0.0.6.

Thanks, I'll take a look.

The fix is quite simple:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<, public static string ForceRemoveLongPathPrefix(string path) { if (string.IsNullOrEmpty(path) || !path.StartsWith(@"\?\")) { return path; } else if (path.StartsWith(@"\?\UNC\", StringComparison.InvariantCultureIgnoreCase)) { return @"\" + path.Substring(@"\?\UNC\".Length); } else { return path.Substring(@"\?\".Length); } } <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Regards, Kim
