Try renaming the file. If it is successul then proceed to copy the file and do what ever is necessary. If the renaming fails then someone else still has it open.

>Our client uplaods files into a DOS PC. A FoxPro application copies files from the DOS machine into another folder. The upload connection is slow and usually files are quite large. I do not want to copy a file while it is still being uploaded. I tried FOPEN() with read-write unbuffered option hoping that it will fail while the file is being uploaded, but it doesn't. To confirm this, I opened a text file on my local drive using Notepad, and I was able to open it using FOPEN() and I was also able to write into it using FWRITE()! (while it was still open in Notepad).
