Hello @BLUEFROG,
I am using WebDAV protocol on a Synology NAS. What you see on Mac Finder is actually the files/flders saved on Synology NAS.
1- The indexed folder is “1_tech_materials”
2- Indexing
3_I read it but I cannot claim that I know it in and out (yet).
The group titled “test group created on DT” was created on DEVONthink, and as soon as I created it, a folder titled “test group created on DT” appeared on Mac Finder (that is what I referrd to as sync. Pardon me if my use of the term “sync” is inaccurate). In the same way, The folder titled “test folder created on Mac” was created on Mac Finder, and as soon as I created it, a group titled “test folder created on Mac” appeared on DEVONthink.
I hope this explaantion is helpful.
