Backing up Opera

It is recommended that you regularly back up your most important Opera files. You should also always back up your files before upgrading.

The tips below are also useful if you need to move your Opera files from one computer to another.

Locating your files

From the menus, choose Help > About Opera, or go to opera:about to find the exact paths for your profile and data folders.

Selecting files

Not all files and folders listed below will be relevant for all users. If you have made no changes to the keyboard, mouse, toolbar, or menu setups, for example, there is no reason to make copies.

The default on Mac is to follow the platform convention of splitting up user data in three different folders. As a result, Opera is integrated with system services (including backup and cleanup routines) with no additional effort. The three folders in the user’s Home folder are:

~/Library/Application Support/Opera/
larger data sets including extensions, mail, and custom build preferences (example: settings for the Mac App Store version of Opera)
temporary files including icons, thumbnail, and cache
the Opera preference files and other small files

Note that since Mac OS 10.7 ‘Lion’, the Library folder in the users’s Home folder is hidden by default. From a Finder window, press Command–Shift–G to enter a folder path manually.
