  * for when files and folders in the trash bin will be permanently deleted.
  * The app allows for two settings, a minimum time for trash bin retention,
  * and a maximum time for trash bin retention.
+ *
  * Minimum time is the number of days a file will be kept, after which it
- * may be deleted. Maximum time is the number of days at which it is guaranteed
- * to be deleted.
+ * _may be_ deleted. A file may be deleted after the minimum number of days 
+ * is expired if space is needed. The file will not be deleted if space is 
+ * not needed. 
+ *
+ * Whether "space is needed" depends on whether a user quota is defined or not:
+ *
+ *  * If no user quota is defined, the available space on the Nextcloud data 
+ *    partition sets the limit for the trashbin
+ *    (issues: see https://github.com/nextcloud/server/issues/28451).
+ *  * If a user quota is defined, 50% of the user's remaining quota space sets 
+ *    the limit for the trashbin.
+ *
+ * Maximum time is the number of days at which it is _guaranteed
+ * to be_ deleted. There is no further depenency on the available space.
+ *
  * Both minimum and maximum times can be set together to explicitly define
  * file and folder deletion. For migration purposes, this setting is installed
  * initially set to "auto", which is equivalent to the default setting in
  * Nextcloud.
