> Am I the only one who never uses a file browser?
You are not alone. When I first came to Linux there were *no* fast file managers except possibly the norton commander clones (which I just don't like). Of the more explorer-like managers the fastest was gmc, but it was still slower than windows explorer had been on the same hardware. It was so incredibly painful to do any of the simple file management activities that I was accustomed to doing via GUI file managers that I took up using xterms for my file management, which forced me to learn command line tools more thoroughly.
By the time any good options existed I couldn't go back to GUI managers and now I just never use them. Today there are only two good choices of explorer-style file manager anyway: pcmanfm and dolphin. Everything else is brain damaged, horribly slow, or both. The best Linux file manager I've ever seen was endevour2, but it seems to have fallen off the internet at some point.
