File stores computer name
It would be awesome if files synced in OneDrive could store the name of the computer which most recently edited it. This metadata exists in files, so OneDrive could easily store it within the file
Currently, files are considered as being created on the local computer, so the computer name of the OneDrive file is the name of the local computer
Not all file formats allow for attachment of metadata, notably very common simple files
The rule for share drive to work is only the first user that open a particular file can edit, save the file. The 2nd or 3rd or 4th...etc. user should not be able to edit ANYTHING until the user(s) prior him or her exit the file. This is common sense for share drive, I don't understand why we even discuss to create same file with different computer name to confuse the users? So in this case, which file is the most accurate one.
