=====Data Directory Location=====

By default, Zotero stores files in a folder within the Firefox profile directory. It is possible to change this location. Zotero will not, however, copy over existing data to the new location. If you want to keep your data, you need to move the files manually. From then on, Zotero will store newly created data in the new location. Clicking the "Show Data Directory" button will open the Zotero directory in your default file browser.

=====Database Maintenance=====

**Check Database Integrity** - Checks for any data corruption in the Zotero database. Database corruption is rare, with most cases originating from older Zotero installations used with Firefox 2.

**Reset Translators and Styles...** - Clicking this button will reset the translators and styles to the current Zotero defaults using the latest versions from the Zotero server.

=====Debug Output Logging=====

See [[/support/debug_output#debug_output_logging|Debug Output Logging]].

=====OpenURL=====

OpenURL is a standard which makes it easy to locate a physical copy of a Zotero library item. Many libraries operate their own OpenURL resolvers, which parse metadata from requests sent by programs such as Zotero, and give the physical location of a particular publication or document. By default, Zotero uses the WorldCat resolver, which is able to search a large number of libraries and find one close to you. If your institution has its own resolver, it is a simple matter to make it the default. Simply specify the URL of the resolver here (your librarian can probably provide you with it) and make sure Zotero and the resolver are using the same version of the OpenURL standard. Odds are it will be version 1.0, but some still employ version 0.1.

Now all you need to do to find a physical copy of an item in your Zotero library is to select the item and click on the "Locate" button under the "Info" tab. This will open a page in your browser with the necessary information.
