“Quick access” is a feature in File Explorer that pins favourited and frequently used folders to the top of the sidebar. Having important and regularly used folders in Quick access makes them easier to find and quicker to get to. Compared to having to find the right folder manually every time.
It’s really easy to add a folder to Quick access. To do so, locate the folder in File Explorer, right-click on it and then click “Pin to Quick access”.
Once the folder is pinned, it will appear in the sidebar with a little pushpin icon to the right of it.
Tip: You can’t pin files or documents to Quick access, only folders.
To unpin an item just right-click on it and click “Unpin from Quick access”. Similarly, if you want to remove one of the automatic suggestions, right-click on it and click “Remove from Quick access”.
