Search Files: How can Labview �tell� whether a file exits.

[FightOnSCTrojan]

I am trying to create a system that saves data by serial number. The name of the file will be in the format of serialnumber.xls.
My question is, is there anyway to programmatically search whether the �serialnumber.xls� already exists in a directory? (As I need to establish different cases depending whether the file already exists in the directory).

Thanks,

You can use the File/Directory Info function (File I/O>Advanced File Functions palette). If it returns an error code 7, the file doesn't exist.

The simplest method to test if a file exist is to use Access Rights function from the File I/O >> Advanced File Functions palette. If this function gives an error in the error out cluster the file does not exist.

I think the File/Directory Info function is the best answer too because you can check to see if the path is a directory or not. Although it is unlikely that someone will create a "serial.xls" as a directory, whenever I am programming in any language I always check to see if it exists AND is a file or directory (depending on what I am expecting).
