Hi,

is there any support for the "\\?\" prefix on paths on windows using HDF5?
I'm currently having a problem with H5Fcreate failing because the path
supplied to it is too long. Is there any othere solution here?

Thanks,

Teo

I'll take a look at it. In the meantime, have you tried doubling up the backslashes (i.e., \\\\server\\share<file:///\\\server\share>, or possibly \\\\server\share<file:///\\\server\share>)? I think we have a "slash-fixer" routine that converts them but I'm not sure if it's smart about the \\server\share<file:///\\server\share> format.

UNC paths (\\server\share ) do, in fact, work with HDF5. I gave it a quick test this morning and \\\\server\\share<file:///\\\server\share> works fine.
