Perforce will not transfer deleted files

I am using perforce and I have a folder ../dev

with my code, a folder ../trunk

with tested code, and a folder ../rel

for code ready to be deployed to production. The way I work is what I am working on ../dev

and when I have a stable release I go to ../trunk

. After testing, I grabbed ../trunk

and forked it into ../rel

.

I forked ../dev

before accidentally ../rel

, so I went ahead and marked to delete the folder ../rel

. Then I tried to pipe ../trunk

to ../rel

, but perforce doesn't say "Unable to fill in target path when files already exist." So it seems that even if I delete the files that were mistakenly forked before ../rel

, they still exist and I cannot overwrite them with the files ../trunk

.

What can I do?
