I have this code,

showmessage('C:\TEMP\'+openfiles[openfilelist.ItemIndex].ID); if removedir('C:\TEMP\'+openfiles[openfilelist.ItemIndex].ID) then   showmessage('Removed') else   showmessage('Failed');

The message shows C:\TEMP\0 and this directory does exist as the program created it earlier and used files inside it and then later deletes them. I can see the files and directories so I know they’re there. The program successfully deletes the files but does not remove the directory.

If I hardcode the directory it works – this means that it accepts the string C:\TEMP\0 but does not accept C:\TEMP\'+openfiles[openfilelist.ItemIndex].ID both equate to C:\TEMP\0. I cannot hardcode these directories, so what can I do? How do I convert from a string + string to whatever removedir() is expecting. I looked this up at Delphi basics and it’s expecting a string.

I’m confused, since string + string = string. What is going on?

  1. Make sure that neither your program nor any other program have the directory as their current working directory. When you recompile the program this may no longer be the case, so it may be a red herring that the hardcoded value works for you.
