# Moving with Storage Studio versus dragging in Finder

Dragging a folder to another drive in Finder copies it. Storage Studio checks the copy before removing the original, can leave a shortcut behind, and keeps a log you can undo from.

You can always drag a folder to your external drive in Finder, and for a one-off copy that's perfect. Storage Studio's **Data Parking** is built for a different job: freeing space on your Mac without breaking anything that expects the folder to be where it was.

## What Finder does

Drag a folder to a different drive and Finder **copies** it — the original stays, so no space is freed. Hold **Command** while dragging and Finder **moves** it instead: it copies, then removes the original. Either way, nothing is left in the old place, so apps that look for the folder there won't find it.

## What Data Parking adds

- **A checked copy first.** The original is removed only after the copy has been [checked](https://storagestudio.us/wiki/glossary-verified-copy) — by size, dates and permissions by default, or byte by byte if you choose **Thorough**.
- **A shortcut left behind.** **Relocate** keeps the folders where they were and leaves a [shortcut](https://storagestudio.us/wiki/glossary-shortcut) for each file, so apps keep working. See [Move, Merge or Relocate](https://storagestudio.us/wiki/move-merge-or-relocate).
- **A guard against busy folders.** By default it won't start a move if files in the folder changed very recently, and it tells you when an app is holding the folder open.
- **Safe to stop.** Pausing or cancelling never loses data, because originals aren't touched until the end.
- **A way back.** The **Moves log** lists each move, and a finished move can be reverted. See [Moving a folder back](https://storagestudio.us/wiki/moving-a-folder-back).
- **The details kept.** Contents, names, created and modified dates, permissions, Finder tags and other extended attributes, the Locked and hidden flags, hard links, sparse files and shortcuts — plus access lists where the drive can hold them. File ownership isn't kept. See [What a move keeps](https://storagestudio.us/wiki/what-a-move-keeps).

## Using both

Use Finder for quick copies you'll manage yourself. Use Data Parking when the aim is space on your Mac and the folder needs to keep working from its old place.
