Set a autocounter for file saving

[Ashley.w]

Hi

I was wondering if antbody knows of any quick tricks for autosaving files with a look-up to prevent overwriting.

What I would like to do is set the file path and for the labview routine to look in that path for the last file name and add 1 to the file name so the last file is not overwritten.

e.g.  path:                C:\Ashley:\todays_runs

        start counter:  001

You might find the attached picture to be useful.  I simply had a "unique" identifier that saved the data in a tickcount element.  Unique is in quotes because it will only go from (2ˆ32)–1 to 0 (wrapping time).  If this does not work for you, you might want to use a "Get Date/Time in seconds" function to get a more unique identifier.

Here is a quick vi that will return the highest file name. This will work if the file names are numbers only. eg. 001.txt. The file extention doesn't matter, you can chage that.
