  • Very good !

  • Easy to use. I use this program every few months to back up my personal files, Docs, Downloads, Pictures, Videos, Desktop, etc to my 2 terabit backup. After the initial mirror All (copy) now it just takes a few minutes to compare the laptop folders to the backup, new music, photos, videos and a few files here and there. I'll use it forever on all my Linux laptops into the future. Better than Foldermatch on that OS which will not to be named from my lips ever again. I love this program.
