_FILEEXISTS

The _FILEEXISTS function determines if a designated file name exists and returns true (-1) or false (0).

Syntax

theFileExists% = _FILEEXISTS(filename$)

Description

• The filename$ parameter can be a literal or variable 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 procedure.
• The function will use the appropriate Operating System path separators. _OS$ can determine the operating system.
• This function does not guarantee that a file can be accessed or opened, just that it exists.

Examples
