+Deleted Files
+=============
+
+ownCloud keeps a copy of your deleted files in case you need them again. To
+make sure that the user doesn't run out of memory the deleted files app
+manages the size of the deleted files for the user. By default deleted files
+stay in the trash bin for 180 days. ownCloud checks the age of the files every
+time a new files gets moved to the deleted files and remove all files oder than
+180 days. The user can adjust this value in the config.php by setting the
+***"trashbin_retention_obligation"*** value.
+
+Beside that the delted files app take care to never use more that 50% of your
+currently available free space. If your deleted files exceed this limit ownCloud
+deletes the oldest versions until it meets the memory usage limit again.
