dsofile.dll changes lastsaved of non office files
 

Hello,

I'm using the dsofile.dll to read and list properties of closed office
files.
This works fine, but I have noticed when there are non office files in
the same folder,
that their last saved time is changed to the time when my procedure
has been executed.

Does anyone have made a similar experience?
Should I use a work around non office files?

Excel XP SP3
WIN XP SP1
