Total path size is limited to 260 characters up through Windows XP. I
do not know if that has changed with Windows Vista. It may be an NTFS
limitation.
I'm not sure what this has to do with Access but I am curious... Where are
you going to "lose" it to? The maximum length of a file name is 255 or 260
but you don't exactly lose the file extension. Perhaps reading this will
help...
