As a user of the Everything filesystem index program, I (and several others) were mystified as to why it wouldn’t index our Nextcloud folders. It turns out that Nextcloud creates the data directory on Windows systems with the System flag set on the directory. I’ve removed the flag (using the attrib /D -S Nextcloud command) and Nextcloud still appears to function correctly. However, this still leaves the question of why Nextcloud is behaving this way to begin with. Can anyone clarify this behavior?
Just to update everyone, I’ve been using Nextcloud with the system flag unset ever since I’ve posted this, and haven’t experienced negative side effects yet. Still unclear why it’s being set in the first place. I may escalate this to an issue on the github repository for more visibility.
