# Expiration date

The expiration date is used to define when an activated file will be deactivated.

To program the deactivation of an album or an entire category, follow these steps:

1. With the "grid" display mode, go to the album or to the "Manage files" section of the category.
2. Use the "Select all" selection tool.
3. Go to the "Selection" tab, then to "Dates" and set an expiration date.

The album or category, with all its files, will thus be deactivated on the date indicated.
