Hi ..Could anybody advise on how to copy..to usb my bookmarks ..or favorites please ?

Would it be the same with any Linux Distro? copying, then does one paste them to New Distro.

Using Mint 17, Emmabuntus.I reinstall distro every month.

Thank you in advance for any replies

Do you mean browser bookmarks? That would depend on what browser you are using, but most browsers include an option to export bookmarks to a file; the file can then be copied to another location. In Firefox and Seamonkey, that option can be found Bookmarks-->Show All Bookmarks or Bookmarks-->Manage Bookmarks.

Just for curiosity, why do you reinstall every month?

For your browser bookmarks you want to back up I will suggest the add-on Xmarks https://www.xmarks.com/ which will sync your bookmarks with their servers and between Firefox, Google-chrome,etc. and works on Windows, Linux and Mac OS, you will have to create an account but it is free.

Also Firefox and Google-chrome also offer their own bookmarks, password, add-on and theme synchronization.
May I also suggest installing on all your web browser the password manager LastPass https://lastpass.com/ which will sync your password between all your computer and web browser

If it is your file browser bookmarks like for Thunar, Nautilus etc. you should look in your home directory for a hidden file named .gtk-bookmarks just do ctrl h to unhide the hidden files and ctrl h to hide them again.

Hoping this was helpful, good luck.

All program configuration information is held in your home directory, and that includes your browser's bookmarks and any saved passwords. If you have /home on a separate partition, then you can re-install on the root partition leaving everything undisturbed, including the bookmarks. Until my drive had a nasty accident, I had a home partition which lasted through Fedora versions 1 to 14, a Debian installation, and then CentOS. But I too am puzzled as to why you re-install so often!
