• Closes Synology Drive Client #8084

Details of Changes

• Added support for Synology Drive Client, based on GoogleCloud provider.

NOTE: I never used Synology Drive Client for sync before, just for backups, so while in my tests it's working I can't assure it will work for all scenarios since I had to figure out how the information is stored on the database, but maybe I figured it out wrong and it needs some readjustments. When this is added I would like to receive feedback from the users to check if it's working for them too.

Validation

• Built and ran the app
• Tested the changes for accessibility

Screenshots (optional)

Hi, I don't have the possibility to test this, but out of curiosity could you check if in registry under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\ there is any subkey related to Synology folders?

There is one, but just for showing the name of the server, nothing about the folders:

Feel free to ask any other thing you think of.

Thanks, I'm asking because that's where Cloud drives that integrate with Explorer register themselves (and indeed you've found Synology).
If you were to take the key name that has the reference to Synology (by key name I mean the "folder" name, below highlighted for Onedrive) and search under HKEY_CLASSES_ROOT\CLSID\ you should find the same GUID with info about the synced folder (path would be HKEY_CLASSES_ROOT\CLSID\{<SYNOLOGY_GUID>}\Instance\InitPropertyBag).

This is what we do to detect a few cloud drives (OneDrive, Box, iCloudDrive, Dropbox, Nextcloud, MEGA, Amazon Drive).
*Note: I have nothing against parsing the database, I'm just curious if the above would work for synology too.

It seems that it only has a shortcut to a folder that have inside the last folder added, but that seems normal since in Windows file explorer for some reason it only shows the last created sync task:

However, as I suspected conn_id could have multiple values, now my new sync tasks have a 3, so they are not getting detected. I will do more tests and check the database to see if I can found how to know if a task is a backup task or a sync task.

Ok, now it should work in each database. I got the connection id for other database, and in that database there is connection_type for knowing if a connection is for sync or for backup.

I also added the host name to the drive folder as Windows does.

BTW, Files shows all synced folders while Windows only shows the last one:

@BanCrash made a couple of small changes (replaced SynologyDriveConnection with a Tuple, skip invalid entries instead of returning no results). Hopefully I haven't broken anything. If you agree with the changes, this looks good.

LGTM. Thank you! Just tested and still working as expected.
