This software is really simple. Once we have selected the videos it allows us to join them. In its interface we will be able to select the video order (moving the AVI files up and down) until they are in the order of our choice. Once we reach this point, we simply click Merge, and the program will start the process that will merge together both files.
Before joining, we'll have to select the output file and the destination folder. After that, all that is left is to go to the indicated location once the process is finished, although it will also be possible to preview by clicking on the corresponding button of AVI Joiner.
This software may seem rather simple, but the truth is that more often than not, the tasks performed in video editors aren't any more complicated than those that AVI Joiner can perform.
