answer:That’s strange. It must be a configuration, because I have Windows 10 and I don’t experience that… My “This PC” and my OneDrive tabs in File Explorer are definitely separate… but then I’m not very good at remembering to save things to the cloud so there isn’t much chance for an overlap…. This is just a guess—when you got your new laptop, did you transfer everything over through OneDrive? If so, it might be that the folders you dragged onto your new PC are just shortcuts to the OneDrive folders (not full separate copies.) I’ve made that “shortcut to folder” mistake several times, so I know it happens. I’ve found that when I drag large folders from one location to the next, the computer tends to assume I want a shortcut (probably a pragmatic storage-saving assumption, so I can’t complain.) Right-clicking the folder, choosing “copy” and then pasting into the source usually convinces the computer that I meant copy-the-contents instead of change-my-access-location. Alternatively, you can go into the folder and select all the contents to copy, then paste (or at this point, drag) them into a folder already waiting on This PC.
