Hi ​@Daniel49085  Welcome to the Box Community!

If you wish to stop syncing and do not want your files on Box.com to be synced to your device without losing any content, you can uninstall the Box Sync application. Please refer to this article on Uninstalling Box Sync Manually and Box Sync FAQs to learn more.

 Note:

Before deleting the content in the Box Sync folder, make sure your files have been synced. To check this, look for the blue check mark ✔ next to the folder or file name.

This ensures that all your content is synced to Box and will not be deleted from your Box online account.

I look forward to hearing that your PC has been repaired and is back on track. Please let us know if you have any other questions.

Have a great day!
