{{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.'''
