Hi, I wondering if there is a function or something to find a file''s absolute path (ex. C:\windows\desktop\myfile.txt ). I''m basically loading a file like this file = fopen ("myfile.txt", "rb"); Is there a way to find the absolute Path from this? Thanks

Thanks for the Reply

That works but I was hoping it would validate that the file was there (real file) but I guess that just extra work I have to do.

Here is the C Library version

_fullpath (cFullPath, cFile, 256)

Again Thanks

Test the access function:

if ((_access(szFile, 0)) == 0)
{
// The file does exist.
if ((_access(szFile, 4)) == 0)
{
// We have read permission to the file.
}
}
else
{
// The file does not exist.
}

// Dalle

To find out if the file exists you can just try to open it, or use GetFileAttributes or something similar.

By the way, there''s really not much point using functions like _fullpath, because it''s not any more portable than GetFullPathName(), which supports unicode better anyway (otherwise you''d have to use _wfullpath or _tfullpath for unicode support...)
