Hi Anthony,

Thank you for posting your query on the Microsoft Communities.

OneDrive creates a file with the computer name appended whenever a conflict is detected. For instance, if you have a file named "MyFile.txt", OneDrive will create "MyFile-ComputerName.txt" in a conflict situation.

A conflict exists when the file has been updated in more than one place. An easy example is with a computer that's not connected to the internet. If you update "MyFile.txt" on the laptop, the file won't sync right away (because there's no network connection). If you also update "MyFile.txt" on your desktop, when the computer connects to the internet, you'll have a conflict, because the file was updated in two places. As a result, OneDrive creates the conflict copy.

You'll have to manually delete the duplicate files. You can easily remove them by using File Explorer and searching for files that have the computer name in them, for example open File Explorer and navigate to the OneDrive folder on your computer, then search in the top-right for the computer name. All files that have that in the file name will appear and you can delete them easier.

We have re-launched our OneDrive forum from May 21st and old OneDrive threads have been removed. However, some cached files can show up through your web browser.

Hope this information helps. If you have further queries, we will be happy to help.
