DIREXISTS: Difference between revisions

Revision as of 10:30, 24 March 2023

The _DIREXISTS function determines if a designated file path or folder exists and returns true (-1) or false (0).

dirExists% = _DIREXISTS(filepath$)

The filepath$ parameter can be a literal or variable string path value.
The function returns -1 when a path or folder exists and 0 when it does not.
The function reads the system information directly without using a SHELL procedure.
The function will use the appropriate Operating System path separators. _OS$ can determine the operating system.
This function does not guarantee that a path can be accessed, only that it exists.
NOTE: Checking if a folder exists in a CD drive may cause the tray to open automatically to request a disk when empty. To find drives in Windows, use this API Library: Disk Drives

{{Parameter|Example: Checks if a folder exists before proceeding.

IF _DIREXISTS("internal\temp") THEN
    PRINT "Folder found."
END IF
