>>>The problem is that the backup and zipping get done in a couple of minutes, however the file copy can take anywhere between 10 and 60 minutes. I tried to copy the file using low-level file functions, and reporting the progress at about each 2.5% of the total. However, it seems that the OS simply queues copy requests - it reaches 100% in a couple of seconds, and only when I issue fClose() on the target file, it then waits whatever it takes until the actual copying happens. Which basically makes my progress indicator useless.

>Mmm... good idea. The source file is buffered. Didn't find any parameters in the fCreate() command that would influence any buffering, but then I could close it immediately after and do a fopen(cTargetFile, 11) (unbuffered, write-only). I'll see what this gives me.

Dragan, Don't forget to post the result to me.

Another:

... = fcreate()
*** loop
 * progress
 FWRITE(nFileHandle,... )
 FFLUSH(nFileHandle , .T.)
....
