Hi! I’m new to version control with TFVC and I’m not able to understand what the “Check Out” option does. I couldn’t find a true definition and real use case for it. In particular, I’m working in a team. When I compile a certain project, I need to copy two dll files created by the previous build process inside two folders related to different projects, replacing their old versions of the dll files. Now, after building the project, they told me I have to check out the old dll files selecting them and clicking Check Out from Source Control Explorer and I just have to copy the new dll files, replacing the old ones with a simple “copy and paste” inside my local workspace. Why do I need to check out those files? Why can’t I just open my local workspace and replace the old dll files with a “copy and paste” directly?

Thanks in advance for the help!
