Opera Help


By default, Opera caches all content (documents, images, and other content) on webpages. To enable rapid access, Opera uses your computer's memory to store recently visited webpages. It's generally a good idea to let Opera handle memory caching automatically.

To display the cache, type opera:cache into the address field.

Cache options

Opera stores visited pages both in memory and on disk, so they will be available after a restart. To change the cache settings, go to Settings > Preferences > Advanced > History and choose from the following options in the Disk Cache section:

Action How to do it Notes
Empty the cache Click Empty now This deletes all cached content from the disk
Change cache disk size Choose the size from the drop-down list Increase this if you want to keep more local copies of pages, and for longer. Zero means that writing to disk will be avoided as far as possible.
Empty cache on exit Check Empty on exit. This deletes the cache automatically every time you exit Opera
Change how often cached pages are checked for updates In the Check if cached page is updated on the server section, select a less-frequent time interval from the drop-down list for either documents or images The browser checks for new versions when you revisit a page, even though most web content is not updated very often. Checking for changes less often may speed up browsing. Note that you may sometimes have to reload to get the newest version.
