I see multiple files cal conflicted and the file name. What does this mean?

[robertsaron]

In Publisher I created a document called PlayersHandbook. Now and then while working on it, or after I open and close it, I can the following file name: PlayersHandbook (Conflicted).afpub

What does that mean? How does it happen? This becomes very confusing to me, as I am not sure what one is the file I should be modifying. Today I saw two of the files, and then one was just named PlayersHandbook.afpub, so I deleted the other two. 

Is there something I am doing wrong? I can attach the file if needed if someone wants or needs to look at it. This has only happened with the players handbook, and not with any of the individual documents I created first, and then pulled those individual documents into the playershandbook.

Are you using something like Dropbox and opening the file on 2 devices or are 2 people editing/reviewing it?

That's the only time I've seen something like that

Are your work files located in a folder that is directly managed by a cloud service? (OneDrive, DropBox, ...)
That's not good - always save working files on the local disk, and just share or backup them to external disks / storages.

I save the files to locally to my documents folder on my C drive. And then there are 2 different cloud services that look at that location and back them up. yes I am paranoid about losing my files. 

The odd thing is, it is only this one file that has happened to, and it has not happened to any other files. Though this is the file I have modified the most in the last week.

I'm sorry - although I assumed that this follows from the context of the posts, the term local disk also meant that these folders are managed only locally, ie without the intervention of various cloud services.
