The client offers several warnings and notifications when facing certain events. Those warnings and notifications can be configured or simply being turned on or off. To configure warnings and notifications:

Click on Preferences in the main window.
Click on Warnings & Notifications.

Available warning and notification settings

Setting	Default	Description
Prompt for duration when pausing	Enabled	When using the Pause option in the main window of the client, the client will stop all synchronization activities and checks for changed files in the filesystem. If this option is enabled, the client will offer a prompt for the duration of the pause.
Show warning if cloud space is about to be exceeded	Enabled	When using online storage (cloud space) for backing up / synchronizing folders, this cloud space most probably has a space restriction. If this option is enabled, the client will issue a warning, when more than 90% of the cloud space is in use already.
Show warning if no direct connection is possible	Disabled	The client can synchronize folders via a direct data connection using port 1337. This is usually the fastest type of synchronization. There are also fallbacks to other methods like relayed traffic by a server, tunneling, etc. If this option is enabled, the client will issue a warning that there is no direct data connection possible.
Show warning if synchronization is running when exiting	Enabled	To make sure the client finishes the synchronization before shutting down, you can enable this option. If this option is enabled, the client will issue a warning if the synchronization is still running and will offer options to keep it running or to exit anyway.
Show warning on possible filename problems	Disabled	Different systems have different sensitivities for case problems in filenames, e.g. 'Folder' is on Linux a different directory than 'folder'. On Windows it's the same. The client will issue a warning and offer three possible solutions for the conflict if this option is enabled: Sync anyways - will take the file with the latest change date and overwrite the older one. Rename - rename the file to solve the conflict. Do nothing - don't sync, don't rename, don't overwrite.
Show warning when folders are out of sync	Disabled	There might be situations, where a folder has not been synchronized for a certain amount of time, e.g. when other members of a folder were offline for a while. If this option is enabled, the client will issue a warning after 10 days. The amount of days can be configured separately using the option below.
Warn after (Days)	10	Specifies the number of days after which a warning will be issued, which makes the user aware of an unsynchronized folder.

Configuring desktop notifications

The client shows notifications for certain events using a desktop notification, means a small pop-up overlay showing up in the right lower corner of the desktop. Those notifications can be configured.

Setting	Default	Description
Display system notifications when minimized	Enabled	Specifies if the desktop notifications should appear even if the client has been minimized.
Transparency	0%	Usually the desktop notifications are not transparent. However it is possible to define a transparency not block complete parts of the screen.
Delay (seconds)	10	Specifies after which amount of time the notification should disappear automatically.
