Hello Dopus Community & Support,
I am working in different locations with different PCs on the same file structure, which resides on OneDrive (and uses different paths on the different PCs).
Then for example, when I add color markers to files or folders in Dopus, these do not appear on the respective other PC.
Is it possible to store the information about such color markers etc. independently of the local Dopus installation, for example directly in the file system?
It is already stored there. Unfortunately, no cloud storage syncs the info 
Aaahrg what a bummer 
Because color-marking of files is becoming increasingly important for me: is there really no possibility for a workaround so that color-markings are also synchronized via cloud storage?
There’s no reason cloud storage couldn’t sync the ADS metadata; they’ve just all apparently overlooked it or decided not to bother.
I don’t know if anyone has tried asking them to add it.
Could I maybe somehow get around this problem by using Descript.ion files?
You could set descriptions on files, and then configure Opus to color files with specific descriptions in different colors. The colors would not appear as quickly but it should work.
How well the cloud service keeps the descript.ion file in sync is another matter. (For example, if two offline clients both modify it and then go back online, cloud storage is going to overwrite one with the other rather than merge both together.) If your devices are always online then it should be OK.
Wow, Opus can do that? Awesome!
Normally, only one of the devices is online, and files are being edited on that device.
I believe there would then be no problem with Descript.ion files, because these will also be kept up to date along with the respective changed files (or file properties) by the respective device that is online.
When then the other device goes online, files are simply synced as before, and additionally the descript.ion files as well.
Correct?
Sounds OK to me, but I don't know the exact details of how each cloud storage vendor does it synching, so I can't say for sure.
