RE: Problem with Big File Name

My two cents:

I think which API the OS (or filesystem?) uses might have something to
do with it, too. At my last job we used InstallShield. It created some
rather deep directories and worked fine, but then I couldn't delete
these directories because the paths broke the 255 character limit.
InstallShield could create fine (good API) but Windows itself couldn't
delete them (bad API.) I think we were using Win2K and NTFS, but I can't
be sure since I don't work there any more.

To delete these things I had to rename some upper level directories to
shorter names to get the full path name down below 255 characters. Then,
of course, I made InstallShield work right. ;)

That's not entirely true. A path can be MUCH larger than 256
characters. But it depends on which APIs you use and what format the
path is expressed in.

Individual names in the path can be up to 255 characters long. The
entire path can be about 32k characters long.

My guess is that the APR library is using the more limited APIs.
