Not really clear, neither the symptoms nor what you did:
- tried to access
- files would not list
- folder is accessible
- contents is not accessible
- changing ownership
Did you try to TAKE OWNERSHIP of folder and files?
Did you try command mode (dir, attrib, xcopy)?
Did you try what a Ubuntu Live CD thinks of it?
Remember: having one copy only (the original) = having no backup. That's a pity. 1.66 GB is less than half of a burned DVD. Would have been a good investment of your time.
Recently I had to re-install Windows XP Media on my Dell Dimension 5520. Prior to the re-installation process, I moved/copied many of my pictures, music, spreadsheets, DOCs, Slide Shoes, PDFs, etc. to a generic FOLDER on my C:\ drive, because my flash drives were full.
After system recovery was completed, I tried to access these files. However, the files would not list. Properties of the FOLDER indicates it contains 1.66 GB of information. The FOLDER is accessible, but not its contents.
I tried changing ownership of the FOLDER, performed security and permission checks. I even ran two different Registry Cleaning-Fixing Software applications. And, scanned the computer with the latest McAfee anti-virus software. No change.
I now have a FOLDER that contains 14,250 invisible files! Is there a fix for this?
