After finishing of backing up, all names of my files in my book essential was changed. In the end of each file was add this - @. Why??? How i can changed it?

Try typing in normal mode it won’t get you help faster like this. Is the data accessibble with Smartware or whatever you used for backup? Smartware uses it’s own method for backup.
