Save your Exchanger
Click 'File', name your file 'wallet', and save it as a '.dat', on a USB key preferably,
or other external hard drive. If you reinstall the wallet, or something, simply put
your save in your Roaming file (C:\Users\(YourPcName)\AppData\Roaming\Om),
that I suggest your pin to your Windows Start or Quick Access.
I recommend you encrypt, as injoncted by the program.
