Issues with autosaving of documents causing multiple copies of document to generated in the OD4B.

Does the applicaton save to a local folder that is sync'd to OD4B?  If so is it a case where the application has completed the save to the local folder and while the Sync client is still working on uploading the file to OD4B the application saves the file again?  What happens? Does it create a file with a  new name in the local folder? Could this be replicated by creating two files with the same names in two different folders on your computer.  Then copy one file to the local folder that is sync'd to OD4B, but before the sync is finished copy the other file (with same name) to the same local folder that is sync'd to OD4B.   I am surprised you would even be able to do this. Would the problem go away if you saved directly to the OD4B library? If so, maybe a mapped drive using a program like Webdrive 2016 would allow your Application to save directly to OD4B.  You could also map a drive without a program like Webdrive, but it is not very reliable.  Note: I am a newbie with Webdrive, I just mentioned it because it has been giving me a reliable mapped drive to SharePoint Online and OD4B. I have only been using it lightly.
