Hello Bert,
yes, confirmed, providing absolute paths without the prefix \\?\
works. As you mention, we just have to know which function requires
the prefix, or has it implicit or does not support it at all.
Thanks for your clarification.

Subversion uses the APR library which handles the escaping for
specific API functions that allow this trick. The ‘\\?\’ style
paths are not a different path, but just the original path escaped
for a specific api.
(Some Windows APIs allow this trick, others just support long paths
directly and then there are functions that support neither. By
passing the long path yourself you assume that all filesystem
functions have this long path support)
If you pass absolute paths to svn, it should support long paths
directly. (Windows doesn’t support long relative paths). Subversion
1.7 will probably work better with long relative paths, as it will
use absolute paths internally for almost every operation.

Subject: long path names on windows prefixed with \\?\ not handled
by svn commands
Hello,
running svn client commands other than svn checkout on windows fail,
if the path name (of the local working copy location) is prefixed
with \\?\.
The prefix is required for path names longer than 255 or so.
It seems that svn commands like svn info or svn status behave
different
than svn checkout command regarding the path name prefix.
example:
svn info \\?\c:\long\path\name
svn: '\' is not a working copy
Any thoughts?
(I am using svn client version 1.6.11 from CollabNet)
Thanks,
Heinz
