Hi Riley,
Welcome to the Box Community, I'm happy to help!
If you are using Box Sync for the first time, you must mark your folders in Box.com first for sync in order for them to be downloaded by the Box Sync app into your local computer.
Here is an article from our Community site that walks through this with screen-shots.
If you've already done this but still folders do not appear in the Box Sync folder, please check to see if there are any errors syncing on your local machine.
Here is how you can check:
- PC: click on the blue Box Sync icon in your Windows System Tray
- You should see 'files synced' at the top if all of the content marked for sync on Box.com is successfully synced.
If you see 'error syncing # files' please click on that and it will generate a pop up listing the ignored files and the specific error message. This article also walks through each error message and potential troubleshooting steps.
Hope that helps! If you have questions, please let me know and I will do my best to help you.
Regards,
