A file appearing in a second place does not always mean you have a second independent copy. You may have moved it or created a shortcut to the original. Before reorganising important folders, clarify which action your application is offering.
Describe the intended result
If you want two independent files, say “copy.” If you want the same file in a new location, say “move.” A shortcut generally points to another item rather than duplicating its contents, although labels and behaviour vary across systems and services.
For a cloud service, check its own documentation before assuming the local file-manager behaviour applies. Shared permissions, synchronisation, and special shortcut features can affect what other people see.
Practise with an unimportant example
Create a small test document in an appropriate folder and try the intended action. Inspect both locations afterwards. For a shortcut, identify the target using the application’s information panel rather than deleting the original to see what happens.
Only then apply the understood action to the real material. A clear description of the desired outcome prevents many confusing folder operations. It also makes support questions easier: “I wanted a separate copy, but this item still points to the original” is much more useful than saying that the file somehow moved twice.
