Splitting filename string 1

[LEICJDN1]

Need to output only part of a filename to results file after main portion of program completed.

Typical openpicturedialog.filename result is c:\files\ecgs\...\100001.JPG

I need to extract only the '10001' part to act as the name for that row of comma seperated values in the results file.

How can I derive this from the filename string?
Is it some use of filters or is there a better way?

Thanks.

Thank you,

Combined with changefileext function and works a treat! Spent ages combing help file for file name functions but failed to unearth both of those!
