_DIREXISTS

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

Syntax

dirExists% = _DIREXISTS(filepath$)

Description

• 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

Examples

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

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