My program uses findfirst() and rename() to remove all files from a
folder. And then it executes RemoveDir() and this fails.

When I try to remove the empty folder with the Windows Explorer, this
fails.

When I close my C++ program, I can remove the folder with the
Explorer.

It appears that my program locks the folder. Is there a remedy?

I'm guessing you still have the "find" open.
findclose() might help

I don't know how rename can delete a file.  DeleteFile, remove and unlink 
all can do that and are provided.  Try using one of them.

If the directory in question is selected as the current directory then it is 
active and Windows will block its deletion.  You can find the current 
directory setting with GetCurrentDirectory and alter it with 
SetCurrentDirectory.

All of DeleteFile, GetCurrentDirectory and SetCurrentDirectory are Win32 API 
functions.

Don't forget to use findclose after finishing with findfirst and findnext.

By giving it a new path.

That worked! I never knew about the existence of findclose(). The help
file has an example without it, so how was I to know that findclose()
existed?

Rename() doesn't delete a file, but it moves the file to another
directory, so that the source directory becomes empty. I do not follow
your suggestion to use DeleteFile(), since that's not what I want.

Yes, that worked. It's not in the help file.

That moves the file to a new directory on the same drive.  It does not 
delete the file.

I never said that I wanted to delete any file.
