I used to use slackware and then decided to change to Fedora.

I copied a folder over from slackware and now root cannot modify the files in any way. It says I do not have permission but I am logged in as root. I cannot change permissions either.

Is there any way to fix this?

I assume it is because the way the files identify root is different on slackware and therefore the files have a different type of permission or something. I'll emphasise that I am a linux newbie, so forgive my possible ignorance

Thank you in advance for any advice or help.

What are the ownerships and permission of the file at the moment? Could you do ls -l on the directory containing the file and show us the output?
