This adding of a "-hostname" (where hostname is a Windows computer name) as suffix to file names definitely is a OneDrive phenomenon that happens when OneDrive notices or suspects simultaneous updates to the same file from different machinery.
File Name Suffixed by Computer Name
I have just noticed that most of my frequently used documents have a very strange file name. Basically the last version but one has the valid name and the latest has the valid name suffixed by the computer name.
So, my PC name is KenLap10
an example is a file that should be investments.xls
the previous version is named investments.xls
the current version is name investments-KenLap10.XLS
This has happened to about 10 current documents in my data folder but also to about five that I haven't touched for months and you can see by the file size that it hasn't been changed. I might have thought that this was down to my using an ancient version of Office but I have seen it happen to .txt files also.

Probably the only thing I did around this time was to switch off OneDrive.
My PC is Windows 10 Home 64 bit
Yes, both versions exist side by side
I thought virus but my Norton 360 is fully up to date
No, didn't join a domain
The problematic files are not in one folder but they are in one tree - c:\data\ken and all its sub-folders. This is where I keep my data and not within my profile so I don't think OneDrive accessed it.
thanks,
Ken
