VS Code Extension
Right-Click Duplicate
LiveRight-click any file in the Explorer and create a copy of it in the same folder, named automatically — no manual copy/paste/rename dance.

Why it exists
The one context-menu option Explorer is missing
One click, not three
No more Copy → Paste → rename. Right-click a file, click Duplicate, and the copy already has its own name.
Auto-incrementing names
First copy is "file (copy).ext"; duplicate again and it's "file (copy 2).ext", and so on — never overwrites an existing copy.
Multi-select works too
Select several files first, then right-click, and every one gets duplicated in the same pass.
