Is there any way to merge multiple games into a single PGN so that when opened I can look through each of them without opening them separately? I'm currently using Scid to Look through games and open my PGNs.

Just realized I could open them in Wordpad and edit them. No help needed unless there is a faster way.

If you're already using Scid, instead of opening them, you can Import them all, then Export them all to PGN.

Don't do this while in an important database! Switch to the clipbase first, or if the total amount of games is greater than the limit (50,000?), create a new database to do this in.
