When you unlink your computer, Dropbox will prompt you to sign in again.
Relink a computer from the desktop app
If you sign in with the same account, the app will seamlessly resume syncing for the Dropbox folder in the existing location. If the location or name of the folder has changed, you'll need to select this location or manually merge the content of the folders (instructions below).
If you link your computer to a different account, the app will detect that another Dropbox folder already exists on the computer. It will then give you two options at this point:
- Choose Another Location: If you want your new Dropbox folder to be in a location different than your existing folder, this option will allow you to choose another location for the new Dropbox folder tied to the account you are linking
- Install: If you want your new Dropbox folder to be in the same location as your existing one, choose this option. This option will rename the existing Dropbox folder to Dropbox (Old) and will create a new Dropbox folder for the account you’re currently linking.
Manually merge the contents of two Dropbox accounts
Manually merging is useful if you want to transfer all your files to a new Dropbox, or combine two accounts with different files. Follow the steps below to merge your Dropbox accounts.
- Note: This process will not transfer membership to shared folders—it will only transfer the folders themselves. If you choose to merge accounts, you may need to rejoin any shared folders you were previously a member of.
Instructions to manually merge:
Let’s call the account that you want to copy contents from account A. Account B would be the second account where you want to place all the merged files.
If you copy folders or files with the same names from one folder to the other, the recently copied files will now have a (1) appended to their names to indicate that they’re different from the existing version. You should manually decide how to resolve these duplicates.
- Sync all of account A’s content to a computer. You can accomplish this by signing in to your desktop app and syncing account A’s content to this device. Make sure all of account A’s content is synced down by verifying that Selective Sync is not enabled.
- When account A is done syncing, you can unlink it following the instructions above.
- Log in with account B and choose Install. If you’re merging two personal accounts, the Dropbox folder for account A will be renamed Dropbox (Old) and account B will now be using the new Dropbox folder.
- Locate the Dropbox (Old) folder, from account A, in your computer and open it.
- Locate the Dropbox folder, for account B, and open it.
- Copy or move the files from the Dropbox (Old) folder (account A) to the new Dropbox folder (account B). If you receive a message indicating that there is already a file named “.dropbox” in your new Dropbox folder, choose “Don’t copy”.
- The merge will be completed after you finish copying or moving all the content desired to account B’s Dropbox folder and the changes sync.
