How can I create a custom formula that checks if a PC file exists? (CR10)

Question

Hello,
I need to create a formula that validates whether a PC file exists or not to display a message ('File Found' or 'File not found'). I created a custom formula that displays the appropriate message based on a report field composed of the FilePath + FileNameWithExtension that works correctly if the field includes a value or not (Basic Syntax below):
If {ctDocumentImages.ImgPath} <> ""  Then    Formula = "File Found"Else    Formula = "File not found"End If
Now I want to validate that the {ctDocumentImages.ImgPath} value corresponds to an existing file; that is, I need to check that the file specified at {ctDocumentImages.ImgPath} location truly exists to determine that the file is actually 'found'. How can I accomplish this?
Any help is greatly appreciated,
Lucio

( my file connection name was CrystalReports_Reports.File Name)  I have generated a report, that shows all my rpt file names, size, last updated.... etc )
Go to database expert, create new connection, select file system data, your starting directory will be
genplex\E\JEMS51_Server\Imaging\Int\2007\.....  you can then report on the file names found in that directory / subdirectory, etc...  When creating the link you can select all files, or just *.rpt  for example
Ok, so you define more than one connection on your report to be able to access the File System Object, right? The problem is that my reports are generic and meant for distribution for customers where no generic base folder will exist. The value of the starting directoy is then unknown, FilePath+Name then can be any value.
