Scheduled file deletion
Slideshow allows you to schedule automatic deletion of files at a specific date and time. Once a file’s scheduled deletion time passes, Slideshow will automatically remove it from internal storage.
The check for scheduled deletions runs periodically. You can configure how often this check is performed via web interface → menu Settings → Device settings, item How often to check files.
Slideshow uses the system date, time, and time zone for all scheduling operations. Make sure your device’s clock and time zone are set correctly to ensure accurate deletions.
Below are three methods how you can set scheduled deletion of a file.
Scheduled deletion via File Manager
You can set or change the deletion date for file via web interface → menu Files → File manager, right-click the file and pick Schedule deletion. In the dialog, you can pick date and time when you would like to automatically delete this file.
You can check the deletion date by either right-clicking the file and choosing Get info, or switching the File manager into List view. In both cases, the date is listed under "Delete date".
Scheduled deletion in the File manager
Scheduled deletion via setup.csv file
Deletion date can be configured in the setup.csv file included in ZIP archive, USB flash drive, Google Drive or Dropbox.
Scheduled deletion via file name
Slideshow can automatically detect a deletion date if it is embedded in the uploaded file’s name. This works for uploads from any source — including the web interface, FTP, WebDAV, USB drives, Google Drive, or Dropbox.
Use the following naming convention:
{any name}_DEL_{date}.{extension}
Supported date formats are:
yyyy-MM-dd(e.g. 2019-12-07)yyyy-MM-dd HH:mm(e.g. 2019-12-07 13:20)dd.MM.yyyy(e.g. 07.12.2019)dd.MM.yyyy HH:mm(e.g. 07.12.2019 13:20)xxD(e.g. 20D, meaning deletion in 20 days after upload)xxH(e.g. 5H, meaning deletion in 5 hours after upload)

File name is checked only at the moment file is first uploaded to Slideshow. If you want to change the scheduled deletion date afterward, you can do so via File manager (see the first method). Renaming the file after it was uploaded has no effect on scheduled deletion.
