# Synchronizing Text Strings When Upgrading

## Follow These Steps to Synchronize Files After an Upgrade

 When a new version of ProductCart is released, new strings are sometimes added to these files. The process of updating or upgrading your version of ProductCart should include these steps:   
 

- Compare the new versions of the language files with your edited versions. There are many file comparison utilities that can help you with this task.
- Synchronize the two files. That is: add the new text strings to your edited version of the corresponding file.
- Upload the edited file to the include folder, instead of the one included in the ProductCart Upgrade
