Before you respond with "just use GetShortPathNam e" please read the rest.
We have an application that places files on a file server using mapped
drives as it's path of choice. The reason for this is because using a UNC
paths makes the path longer, causing the periodic problem with a path that is
too long (over 260 chars).
We also have an asp.net app that needs to access those files. Accessing
mapped drives from an IIS application is not a viable option due to security
restrictions. UNC paths, however, are good except for the long path problem.
I've tried using the GetShortPathNam e win32 api but it apparently doesn't
accept arguments that exceed 260 characters. Not really helpful. Sometimes
I can get around this by stripping the filename, shortening the directory
path, and then appending the filename back onto the path. However, this
won't work if the directory path is over 260 characters.
So what I need is a way to shorten a path that is over 260 characters, which
is where GetShortPathNam e doesn't work.
Can anyone offer any suggestions?
Thanks,
Jeff

There is no solution for this, other than, to get the file path shorten on
the machine where the file is located. In other words, shorter file path
names on the machine.
Unfortunately shorter file path names is not a viable solution. This is an
Electronic Discovery application for litigation, which means all file names
and document metadata must remain intact.
I think I have a solution that will help. I'm taking the last directory
separator character prior to 260 and shortening the path up to that point and
then appending the rest back onto it. It is working so far but I haven't yet
tested in all of our scenarios.
Thanks for your input.

Hello Jeff,
Use WinAPI and "\\?\" before the path, which switch to the UNICODE path and
allows manipulate with 32k path length

Hi!
I know, that Path-names should be shorter than MAX_PATH (250), but the
Win32-SDK allows specifiying longer names using the "\\?\" prefix.
As I have an application that accesses files directly using the volume
name instead of the drive letter
(i.e. "\\?\Volume{...}\subdir\file.ext"), I sometimes get an
PathTooLongException, as the total string exceeds 260 characters (due to
the "\\?\Volume{...}\"-part).
