Before starting

It is assumed that you've installed Areca using the default procedure of your system (Linux or Windows).
Make sure you've had a look at the previous tutorial (Section 3 : "Merging your archives") before reading this section.

Merging archives

If you want to keep only a limited number of archives to avoid using too much space on your backup location, the "merge" feature will be useful to you.
Go to the "Physical view" and select your three archives :

Right-click and select the "Merge" menu item :

A new window appears :

Just hit the "Start merge" button.
Once the merge is performed, you can notice that only one archive appears in the "Physical view" :

Double-click on it to see its content : you can notice that all files (including "MyNewPicture.jpg") are contained in this unique archive :

If you go back to the "Logical view" and select "MyNewPicture.jpg", you see that the file's history has disappeared. A unique version is now displayed (created at 9:54 PM) : Areca has destroyed the file's history and kept the last version only.
