@FINDCLOSE[filename]: Signals the end of a @FINDFIRST ... @FINDNEXT sequence. You must use this function to release the directory search handle. Filename is unnecessary, this function can be simply called as %@FINDCLOSE[] without parameters. @FINDCLOSE returns 0 if a @FINDFIRST ...@FINDNEXT sequence is in effect, a non-zero value otherwise.
Examples:
echo %@findfirst[*.exe]
echo %@findclose[]
