Here’s a way to remove all the items that are not being used in your project, like deleted takes, unused samples, discarded ideas, etc 🗑

This is something I recommend you do every time you are done with a REAPER project. It will clean up the project and reduce the project folder’s size by a lot!
How to clean project directory
Go to File > Clean current project directory .
In here you will see all the items that are not being used in your project that you can delete.
To minimize risk, I recommend checking the box at the bottom: Send files to trash (safer)

My workflow recommendation
Here’s how I like to archive my projects so they become future proof
First, I save and copy all media items into project directory.
You can do that by going into File > Save as and then checking the box at the bottom for Copy all media into project directory and save into your project folder. (you can overwrite your project file or just create a whole new folder if you want).

Secondly, I run the clean project directory feature from above.
Again, you can find this in File > Clean current project directory .
And there you go 💪– this way you ensure all media will be within the project folder and you can clean up whatever is not used and save precious storage space.
