One of my clients just brought up to me that on a file server there are a number of folders with today's date stamp but no one's modified the actual folder itself and in a couple of cases the only document in the folder is a document or PDF that was put in there last week.
Baffled I went to experiment and specifically every time you open a Word or Excel file in that folder it changes the date modified of the senior folder to right now. In one instance this occured with a PDF file (PDF program was Nitro PDF), otherwise PDFs don't seem to cause this issue. The computer has Office 2010 Starter Edition.
I then tried this on my personal workstation which has Office 2010 Pro - trying it on local folders (not a network folder) I get the same results, just opening an excel or word doc will then change the "date modified" stamp on the parent folder.
I've never noticed this before - really I haven't looked as it didn't matter to me.
Is this normal or is there something I can do to fix this? Is this specific to Office 2010?
Both computers are Windows 7 64bit.
