== File Watcher Settings

Flow watches the project directories in the file system to automatically load the changes.
It uses the **inotify** mechanism on Linux.
Linux systems have a limited number of watches available by default.
Sometimes this limit is too low, so you may have to set it to a higher value.

To check the current watch limit, run the following:

[source, bash]
----
sysctl fs.inotify.max_user_watches
----

The ideal number of watches depend on the number of Flow projects you have, and the number of other apps that adds file watches.

Thanks Amanda,

For many use cases, `250 000` would be a sensible choice.

You can set the number of file watches limit temporarily using the following commands:

[source,bash]
----
sudo sysctl fs.inotify.max_user_watches=250000
sudo sysctl -p
----

To set the limit permanently, you can run the following:

[source,bash]
----
echo fs.inotify.max_user_watches=250000 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
----
