I used to think that the use of this function would be nil too. Even reading the MS docs, they do explain about its limited usage. However, I have had more than one case where a number of programs require this function to work properly.

The most pertinent case is with utorrent downloads of large files.
If the user is downloading a 40GB file and the program wants to pre-allocate the space to avoid fragmentation, it has two options:
1. The OnSetEndOfFile approach, which will zero fill the file and will take a while for a large file
2. The SetFileValidData approach, which is much faster and safe as long as the program intends to fully fill the file with data

Thank you in advanced and looking forward for this callback being supported.

If you like the idea, vote for it on https://www.eldos.com/cbfs/wishlist.php

Sincerely yours
