This icon means that the file is a branch of the main file.

Ah, ok. Thanks @tank666.

It looks like my file has no main file. I can’t see any reference to it - I’ve looked in Active/Yours/Archived tabs under ‘See all branches’. I must have inadvertently deleted it.

I wonder if there a way to make the branch the main file again when there is nothing to merge back to.

I don’t see any references to main file here either 😦

I successfully replicated what I must have done (delete the main file of a file that I branched). You are left with an orphaned branch that displays the branch icon - and no way to make that one the new ‘main’ file.

I guess it’s not a big deal - it’s just the icon.

Thanks for your assistance though @tank666

At least I now know why my file icon is the way it is 🙂
