GitHub with SourceThree ERROR in Push

Question

Now I Create a branch and didn't work

Answer 1

Creating a branch would not be enough to get past the error message "The following untracked working tree files would be overwritten by merge"

You need, with SourceTree, to either:

• stash your untracked file (if you want to keep that untracked file)

• or clean (ie delete) it: it is called discard

right click the files you want to discard (in the Working Copy Changes list), and choose Discard.
