I’m using C++ and accessing a UNC path across the network. This path is slightly greater than MAX_PATH. So I cannot obtain a file handle.
But if I run the program on the computer in question, the path is not greater than MAX_PATH. So I can get a file handle. If I rename the file to have less characters (minus length of computer name) I can access the file.
Can this file be accessed across the network even know the computer name in the UNC path puts it over the MAX_PATH limit?
I recall that there is some feature like using
\\?\at the start of the path to get around theMAX_PATHlimit. Here is a reference on MSDN:http://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx
For remote machines, you would use a path name such as:
\\?\unc\server\share\path\file. The\\?\unc\is the special prefix and is not used as part of the actual filename.
