Foggy Bottoms has asked for the wisdom of the Perl Monks concerning the following question:
Monks of Nepal and abroad, good morning,
I've been wanting to scan my hard drive to find files & folders that'd changed (ie created/modified/deleted). There's a simple of scanning the entire drive and checking to see whether last modified dates have been changed - but it's very time consuming.
Hence, I thought of another way : firstly there's no need to scan if no changes have been made. So a disk scan should only be triggered when a change is detected - that bit was easily solved with Win32::ChangeNotify->new("c:\\",1,"LAST_WRITE");. However this bit doesn't tell me what's changed or where.
Therefore I thought of using a folder's last accessed property, but it so happens that this property doesn't give a complete timestamp - hence it's not precise enough. As for the modified property of a folder, it is not reflected up in a folder tree : if a change occurs 3 folders down in depth then only the directly parent folder is affected.
I'm basically stalling at this point - on one hand I've got this great tool but it returns a "crappy" timestamp and on the other hand I have this really complete timestamp but unfortunately, it's not being reflected on parent folders.
There is some hope however with
Has anyone ever wanted to look up modified files in an efficient way ? Has anyone advice I could use, tips, or help ?
Thanks so much guys...

FindFirstChangeNotification, a C++ method...
