[OpenAFS-win32-devel] Windows client XCOPY.EXE problem.

[Rodney M Dyer]

OpenAFS Bug Tracking RT ticket:  15871

Problem:

When copying a very large tree of directories and files out of
AFS to a local drive with the Windows XCOPY.EXE command, there exists
the potential for XCOPY to fail with an "Invalid Handle" error.

What we know:

* The number of directories in our testing was greater than
500,000. The number of files was greater than 400,000.

* The XCOPY doesn't always stop with the error at the same
location in the tree each time the copy is tried.

* If the same tree of directories and files exists on an NTFS
drive, then XCOPY works without failing.

* WinZIP, the DOS 'FOR /r' command, and DIR /s all perform without
issues.

* XCOPY fails even if provided the '/L' argument to only list the
files that would be copied.
