I'm going to suggest a title you don't see often. It's Gyula's Navigator. Yes, it lacks icons and frills but it does show folders and files even if hidden.
About the crashed computer. We usually can take the HDD out of that and put it into some USB case to get a second chance at redemption.
Using a 6 year old HP desktop running XP. I had all my documents copied on an external hard drive. Computer crashed and I purchased a new Toshiba laptop with Windows 7. when I access my external hard drive it shows backed up copies of Quickbooks (which I'm using for a small business), it shows a folder for music (when opened contains all of my music), it shows a folder for my DVDs, when opened contains nothing.
Most importantly it does not show my photos or data files. They were all "copied" to the external hard drive, not backed-up. (The quickbooks were backed-up but the music files were copied, yet both of visible?)
If I run search I can find various files, but it would take forever to copy them individually.
Why can't I see these files as previously displayed in my documents?
