{{DISPLAYTITLE:_DIREXISTS}}
The [[_DIREXISTS]] function determines if a designated file path or folder exists and returns true (-1) or false (0).


{{PageSyntax}}
: {{Parameter|dirExists%}} = [[_DIREXISTS]]({{Parameter|filepath$}})


{{PageDescription}}
* The {{Parameter|filepath$}} parameter can be a literal or variable [[STRING|string]] path value.
* The function returns -1 when a path or folder exists and 0 when it does not.
* The function reads the system information directly without using a [[SHELL]] procedure.
* The function will use the appropriate Operating System path separators. [[_OS$]] 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: [[Windows Libraries#Disk Drives|Disk Drives]]
