pop3d.log, btmp.1, and btmp files safe to delete from server?

Yes are the following files in the title of this post safe to delete. The reason I am wanting to delete them for is because they are taking up a massive amount of my web hosting space. I am not sure if I should just delete them. Then just upload the sames files, but new ones (with no data)?

 

Yes, you can delete them. they are just log files.

 

Shouldn't I replace the file though right away as well? Make a new one... Or will my server automatically just write a new on there?

 

You can just do "echo > filename" that will empty them. the .1 can be deleted as that was a rollover from the original file and it will be created again when the main log file becomes filled again.

 

I am using File Zilla SFTP. What if I just delete it then upload a new file.. Would that be ok? Just making sure I'd imagine so..

 

It should be fine to just delete.
