Re: CFileDialog multi selection buffer!!!????

Tech-Archive recommends: Fix windows errors by optimizing your registry

It allocates a lot of unused memory, i was looking for somethings that let me
to allocate memory while users select files.
CFileDialog store the path of folder browsed and only the file name of
selected file that has usually less that _MAX_PATH chars...
Than, GetStartPosition() and GetNextPathName() will return the entire path
for each file.

Thanks
