The **_FILEEXISTS** function determines if a designated file name exists and returns true (-1) or false (0).
## Syntax
> theFileExists% = [_FILEEXISTS](_FILEEXISTS)(filename$)
## Description
* The filename$ parameter can be a literal or variable [STRING](STRING) value that can include a path.
* The function returns -1 when a file exists and 0 when it does not.
* The function reads the system information directly without using a [SHELL](SHELL) procedure.
* The function will use the appropriate Operating System path separators. [_OS$](_OS$) can determine the operating system.
* **This function does not guarantee that a file can be accessed or opened, just that it exists.**
## Example(s)
Checks if a file exists before opening it.
```vb
IF _FILEEXISTS("mysettings.ini") THEN
PRINT "Settings file found."
END IF
```
