Dropbox – How to Hide Comments by Default in File Viewer

On Linux, the Dropbox client is subject to a default system limit on the number of directories it can monitor for changes. There is a warning regarding this, along the lines of:

Unable to monitor filesystem

Please run: echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches and restart Dropbox to correct the problem.

This comes up often in the Dropbox Forums, and they have a mention of it in their "Why aren't certain files on one computer syncing to another?" document:

Monitoring more than 10000 folders

The Linux version of the Dropbox desktop application is limited from monitoring more than 10000 folders by default. Anything over that is not watched and, therefore, ignored when syncing. There's an easy fix for this. Open a terminal and enter the following:

> echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf; sudo sysctl -p

This command will tell your system to watch up to 100000 folders. Once the command is entered and you enter your password, Dropbox will immediately resume syncing.

If that user has set the shared file/folder to sync to their computer then yes, it will stay updated when their dropbox syncs.

Keep in mind, though, that there are many ways that the file/folder could be out of sync:

• Other person hasn't turned on their computer
• Other person hasn't turned on syncing for that file/folder
• Other person has Dropbox setup to not auto-sync
• Other person has that file open and Dropbox can't update the file because it's in use.
