Alan, Thanks for the response. I found an API that lists all files open. If the pdf is found, I force the user to close it.

So assuming you know the file exists then lnHandle = fopen(lcMyFileName) if lnHandle = -1 * -- The file couldn't be opened so is open somewhere else. else fclose(lnHandle) endif To close it you would have to find the file handle from the other process, i.e. whatever they're using to read PDF files, and use the Windows API to close that handle. Bearing in mind that they could be using any web browser, Acrobat Reader or any number of PDF readers to view the PDF. Maybe extract it in their temp folder and don't worry about erasing it. -- Alan Bourke alanpbourke (at) fastmail (dot) fm On Tue, 29 Mar 2022, at 4:33 PM, Carl Lindner wrote: > I extracted "d:\test_dir\test.pdf".
