When a file path is very long, I got this:

The webdavlib.jar API tries to write a tmp file on disk and finds the file
nams is too long.  I think to generate that kind of tmp file path could be
replaced by other ways to avoid this problem. Using MD5 to generate a string 
from the original file path could be a choice.
