Hey SuperGama. Welcome.
Go to file and create a new folder. Change the type of folder to Contacts. Pick a location for the folder. Then select all your contacts and right click and dra them to the new folder and select copy. This will copy all your contacts to the new folder.
However, this is still in the Outlook program. So, if you're going to wipe it and reinstall, I am not confident about the ability for the information to be retained.
Why not export the info to a file which you could import later?
