I have source code in TFS. I check it out to my local folder and make changes to some files. Now I need to check it in, but, I never checked them out to start with. How can I do this.
BTW, I never know what file will need to be modified when I start, and I am not working in visual studio.
If you that regularly changing files without checking them out (so no write protection) then you will unevitably loose work regularly because of making some error in your actions.
