Is it possible to create a report to list all files (sheets) in a folder not modified in the last 45 days?
To be clear: I know how to run a report that shows the ROWS modified within the sheets. I want to know when the SHEETS themselves were last modified.
Background: Currently I have a folder with hundred of sheets. They are supposed to be accessed monthly but I suspect many are not. Now I sort the folder by "modified" now to see what is out of date. It's an OK workaround but I'd love a report...
Thoughts?
