I have accidentally deleted some files. In windows it is easy peasy to undelete files but in ubuntu it is like trying to read mandarin. I have downloaded e2undel but haven't the faintest how to use it. I don't understand what mount means. I don't understand how to see where files and directories are (is there no equivalent to windows explorer showing you the tree?). Everywhere I look on the interent it just says how easy it is, and then immediately starts gobbledigook again!
