## Known specifics

- **The copy gets a new ID.** The original stays in its source folder unchanged. The copy identifier (the `data.id` field) does not match the original identifier — use `data.id` for further work with the copy.
- **Copying works between storages.** Unlike the move operation (`POST /v1/files/:id/moveto`), copying is allowed even when the source file and the destination folder belong to different storages.
- **Name conflict.** If a file with the same name already exists in the destination folder, the operation fails with a `422` error. Rename the original or choose a different folder.
