These recent videos have been great. I'd love to see a similar style video series for admins. One key thing I would like to see is backing up and recovering a server

Awsome serie of video. I'd love something similar more in depth about using helic core with Unity (how to deal with settings folder, checking out directly in Unity editor, how the best to organize streams in a multi platform project...)

When using undo changes feature do note that you can't tamper the state of the file before submitting. So for example, if you want to do incremental changes from a prior revision, you'd have to commit the rollback CL first then checkout the file to do the next set of changes on head revision. This can have undesired effects when working with a team, for example of the latest version is still somewhat usable, but you have to move the file for everyone to the older version before you can make your changes and submit your fix. What we do instead is often get an older revision, duplicate the file, get the latest again in p4v to move it to head revision, then clobber the file with the copied older revision in Windows Explorer. This way the workspace thinks the file is a head revision and is working towards the next version up. This allows you to release incremental changes without doing a back 1 step then 2 steps forward as two separate CLs.

Awesome, thanks this great tutorial playlist.

If you restore from an older changelist how would you make that the new starting point so when you hit get latest it doesn't just go through and re-add everything submitted after?

Hello! Thanks SO MUCH for the useful guide!! How can I revert back the deleted files without having to redownload all files? If I just uncheck the force operation would that do it?

I have been trying to follow this to roll back recent changes, and i seem to have missed a trick. how do you handle it if it reads that you have errors when you try to go back to a revision?

[SmokeMaxxx]

What about undoing local changes? i.e. before checking the file out I do some changes, but I just wanna go back to what the main repo has.
