Top Forums Programming How to prevent a C++ program reading a file that is still being written to.? Post 302907163 by Corona688 on Thursday 26th of June 2014 11:09:00 AM

Clever methods checking timestamps can't tell the difference between a completed upload, a slow upload, a stalled upload, and a broken upload. It's the client application's job to tell you when the file is complete, your server-side one cannot psychically know without its help.

Often this is accomplished by having the application upload to one folder, then having the same application move it to another folder when complete -- as long as the folder is on the same partition, files will seem to 'appear' in it instantly and whole once a download completes, and never before.
