Sometimes I “Mark for Add” and add files to Perforce which I actually didn’t want Perforce to worry about.
Is there a way to revert it so it just goes back to showing in P4V as an “untracked” item?
See my example:
I’ve added mil.ico and mil3.ico by mistake. I just want them to go back to looking like test.ico, ie. ignored by Perforce:

Even if I save a copy of the files, then delete, then put them back (all of which is a serious bore), P4V still knows they have a history and marks them as shown:

I just want Perforce to leave a file alone when I tell it to.
If you want to remove the last traces of the files from perforce, your only chance is through
p4 obliterate. This will irreversibly remove file revisions or even file’s complete history from perforce and will only work with administrator privileges. I don’t know if obliterate is available through p4v, on the command line you would issue:and if it looks like you and perforce agree on the file to forget
to seal the issue.
