Purpose |
Determine whether or not a folder exists. |
|
Syntax |
FolderExists& = ISFOLDER(FolderName) |
|
Remarks |
The file subsystem is checked to determine whether the folder specified by FolderName currently exists. If it is found in any form (hidden, system, read-only, etc.), the value true (-1) is returned. Otherwise, the value false (0) is returned. The root directory (for example, "C:\") is considered to be a folder, and returns the value true (-1). FolderName is an unambiguous file name, which may not contain an asterisk (*) or query (?). If it contains one or more of those characters, the function always returns false (0). |
