Managing deleted files
|
|
======================
|
|
|
|
When you delete a file in Nextcloud, it is not immediately deleted permanently,
|
|
only moved into the trash bin. It is not permanently deleted until you manually
|
|
delete it, or when the Deleted Files app deletes it to make room for new files.
|
|
|
|
Find your deleted files by clicking on the **Deleted files**
|
|
button on the Files page of the Nextcloud Web interface. You'll have options to
|
|
either restore or permanently delete files.
|
|
|
|
Quotas
|
|
------
|
|
|
|
Deleted files are not counted against your storage quota. Only your personal
|
|
files count against your quota, not files which were shared with you.
|
|
(See :doc:`quota` to learn more about quotas.)
|
|
|
|
What happens when shared files are deleted
|
|
------------------------------------------
|
|
|
|
Deleting files gets a little complicated when they are shared files, as this
|
|
scenario illustrates:
|
|
|
|
1. User1 shares a folder "test" with User2 and User3
|
|
2. User2 (the recipient) deletes a file/folder "sub" inside of "test"
|
|
3. The folder "sub" will be moved to the trash bin of both User1 (owner) and
|
|
User2 (recipient)
|
|
4. But User3 will not have a copy of "sub" in their trash bin
|
|
|
|
When User1 deletes "sub" then it is moved to User1's trash bin. It is
|
|
deleted from User2 and User3, but not placed in their trash bins.
|
|
|
|
When you share files, other users may copy, rename, move, and share them with
|
|
other people, just as they can for any computer files; Nextcloud does not have
|
|
magic powers to prevent this.
|
|
|
|
How the deleted files app manages storage space
|
|
-----------------------------------------------
|
|
|
|
To ensure that users do not run over their storage quotas, the Deleted Files
|
|
app allocates a maximum of 50% of their currently available free space to
|
|
deleted files. If your deleted files exceed this limit, Nextcloud deletes the
|
|
oldest files (files with the oldest timestamps from when they were deleted)
|
|
until it meets the memory usage limit again.
|
|
|
|
Nextcloud checks the age of deleted files every time new files are added to the
|
|
deleted files. By default, deleted files stay in the trash bin for 30 days. The
|
|
Nextcloud server administrator can adjust this value in the ``config.php`` file
|
|
by setting the ``trashbin_retention_obligation`` value. Files older than the
|
|
``trashbin_retention_obligation`` value will be deleted permanently.
|
|
Additionally, Nextcloud calculates the maximum available space every time a new
|
|
file is added. If the deleted files exceed the new maximum allowed space
|
|
Nextcloud will permanently delete those trashed files with the soonest expiration
|
|
until the space limit is met again.
|
|
|
|
.. note:: Your administrator may have configured the trash bin retention period
|
|
to override the storage space management. See `admin documentation <https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#deleted-items-trash-bin>`_ for more details.
