A Microsoft file hosting and synchronization service.
Hello
If you want your files to come back to local path instead of nesting in OneDrive folder, you need to go to OneDrive app settings > Sync and backup tab > Manage backup, and turn off those folders.
Restart the computer, and the folders should go back to local path.
If any files are missing after that, you can download them from www.onedrive.com > My files.
