VSDC how to join two split clips

[OldNick]

I cannot believe how hard it is to find out this. However.

I have a single clip and in the midst of it I split it into 3, so I could do slowmo in the middle segment. But then I decided it was in the wrong place, so I want to join the 3 together and split in a different place. How do I do that, please?

Can't just Undo as this this is a new session with the video from when I did the splits, (so to speak)

Thanks for any help

Need more info,what type of files are they?

Thanks for the reply.

Various types of video; mp4, AVHC mov etc. In this case all the segments have been split from a single larger one, as I said. ATM I cannot even see a way of trying to rejoin them: no button to press to start trying.
