Total Commander is not freeware, but as shareware it's totally uncrippled and never expiring. The only limitation is closing down a nagger at startup.
Besides being the best windows filemanager by a VAST margin, it also has ten tons of plugins/addons, one of them being an ISO viewer/extractor (completely free to get from ghisler.com or totalcmd.net ). IMO you cannot get much better than that.
The free version of ISOBuster should also suffice.
The revolution cannot be a lever, or an essay, or tablaeu, or embroidery. It cannot proceed mellowly, piece-by-piece, gently, devoutly, simply and humbly.
