Multiple copies of DST file are automatically created

Anonymous — Thu, 20 Aug 2020 21:24:33 GMT

AutoCAD randomly creates multiple copies of our Sheet Set DST file. All of our working files are stored on a 3rd party cloud including the DST file. We typically have 2-3 people in the drawings tied to the Sheet Set at a time. When making changes to the Sheet Set, the changes get automatically saved in one of the hundreds of copies. Essentially, the changes we make to the Sheet Set get lost. This makes all capabilities of Sheet Set unusable. Any help to resolve this issue will be greatly appreciated!

>>>... files are stored on a 3rd party cloud including the DST file...<<<
Looks like you might have file versioning or syncing duplicates at the host site: which secret service is that?Does everyone work from a their own synced folder? Is there a desktop app for that service?
You can also ask their support about turning that off.

Yes, it's Dropbox... we all work in a synched folder on our own computers. Looks like that could be the issue, right?

It is worth investigating, I see several topics on the matter over there, like this one from the HELP Center
https://help.dropbox.com/installs-integrations/sync-uploads/duplicate-files
And this one of many more from their forums

SSMAUTOOPEN appears to be a system variable that may be the culprit. Try changing setting to 0.

We are having the same exact issue, but with OneDrive. It does not happen with every sheet set, just some of them... No idea what is happening. Would love some insight!

How many of you sync that OneDrive folder where the duplicated appear to your local drives? That's more often than not why you see the duplicates. It's discussed for a different file-storage service but the issue is the same I believe.
