Slideshow allows you to schedule the date and time when a file should be automatically deleted. This date and time is then checked periodically and once the current date and time is past scheduled deletion, Slideshow will automatically delete the file from its internal storage. Interval how often are the dates checked can be configured via web interface – menu Settings – Device settings, item How often to check files.

In order for scheduled file deletion to work, Slideshow has to have access to a time server on internet. NTP protocol is used for checking the actual time, default server “1.pool.ntp.org” can be changed in the settings under NTP server. Without access to network time server, scheduled deletion won’t be able to delete any file. The reason behind this that most Android boxes doesn’t have internal clock and they will report entirely incorrect date and time without internet access.

Bellow are three methods how you can set scheduled deletion of a file.
