RE: Problem with Big File Name

FYI, I do experience this limit quite a bit in my own programming, most
closely associated with the shlwapi.dll library (PathStripPath and related
API functions)

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.
