In most of the online resource I can find usually show me how to retrieve this information in VBA. Is there any direct way to get this information in a cell?
For example
if you don't want to create a UDF in VBA or you can't, this could be an alternative.
=Cell("Filename",A1)
this will give you the full file name, and from this you could get the user name with something like this:
=Mid(A1,Find("\",A1,4)+1;Find("\";A1;Find("\";A1;4))-2)
This Formula runs only from a workbook saved earlier.
You must start from 4th position because of the first slash from the drive.
