📁👩👩👧👦 Admin configured folders accessible by everyone in a group in Nextcloud.
Group Folders can be configured through Group Folders under Administration settings.
After a folder is created, the admin can give access to the folder to one or more groups, a quota can be assigned for the folder and advanced permissions can be activated and configured.
Permissions to the content of a group folder can be configured on a per-group basis.
The configuration options include the Write, Share and Delete permissions for each group.
Once configured, the folders will show up in the home folder for each user in the configured groups.
Advanced Permissions allows entitled users to configure permissions inside groupfolders on a per file and folder basis.
Permissions are configured by setting one or more of "Read", "Write", "Create", "Delete" or "Share" permissions to "allow" or "deny". Any permission not explicitly set will inherit the permissions from the parent folder. If multiple configured advanced permissions for a single file or folder apply for a single user (such as when a user belongs to multiple groups), the "allow" permission will overwrite any "deny" permission. Denied permissions configured for the group folder itself cannot be overwritten to "allow" permissions by the advanced permission rules.
Users or whole groups can be entitled to set advanced permissions for each group folder separately on the group folders admin page. For entitlements, only users from those groups are selectable which have to be configured selected in the Groups column.
Some settings are currently only exposed via config/config.php:
'groupfolders.quota.default' => -3,
The special value -3 means unlimited and any other value is the quota limit in bytes.
Group folders can be configured and managed from the command-line interface (CLI). This is accomplished by using the occ command.
The occ command is utilized throughout Nextcloud for many operations and is not specific to Group Folders. When the Group Folders app is enabled, the occ command gains additional functionality specific to Group Folders.
If you're unfamiliar with occ see Using the occ command in the Nextcloud Server Administration Guide for general guidance.
occ groupfolders:create <name>→ create a group folderocc groupfolders:delete <folder_id> [-f|--force]→ delete a group folder and all its contentsocc groupfolders:expire→ trigger file version and trashbin expiration (see Nextcloud docs for versioning and Nextcloud docs for the trash bin for details)occ groupfolders:group <folder_id> <group_id> [-d|--delete] [write|share|delete]→ assign groups and their rights to a group folderocc groupfolders:list→ list configured group foldersocc groupfolders:permissions→ configure advanced permissions (see below for details)occ groupfolders:quota <folder_id> [<quota>|unlimited]→ set a quota for a group folderocc groupfolders:rename <folder_id> <name>→ rename a group folderocc groupfolders:scan <folder_id>→ trigger a filescan for a group folderocc groupfolders:trashbin:cleanup→ empty the trashbin of all group foldersocc config:app:set groupfolders enable_encryption --value="true"→ activate encryption (server-side) support
Advanced permissions can also be configured through the occ groupfolders:permissions command, but must be enabled first.
Before configuring any advanced permissions you'll first have to enable advanced permissions for the folder using occ groupfolders:permissions <folder_id> --enable. To do this you'll first need to find the folder_id of the groupfolder you're trying to configure. You can use occ groupfolders:list to find the folder_id of the target folder.
Then you can list all configured permissions trough occ groupfolders:permissions <folder_id>.
occ groupfolders:permissions 1
+------------+--------------+-------------+
| Path | User/Group | Permissions |
+------------+--------------+-------------+
| folder | group: admin | +write |
| folder/sub | user: admin | +share |
| | user: test | -share |
+------------+--------------+-------------+
Permissions for files and folders can be set trough occ groupfolders:permissions <folder_id> --group <group_id> <path> -- <permissions> to set permissions for a group or occ groupfolders:permissions <folder_id> --user <user_id> <path> -- <permissions> to set permissions for a single user.
<permissions> can be one or more of the following options: -read, +read, -write, +write, -create, +create, -delete, +delete, -share or +share to set the set the respective permission to "deny" or "allow".
You can delete a rule by passing clear as the <permissions> field.
Note: An advanced permission settings set always needs to be complete (for example +read -create +delete) and not just incremental (for example -create).
Not mentioned options (in the above example that's write and share) are interpreted as inherited.
To help with configuring nested permission rules, you can check the effective permissions a user has for a path using occ groupfolders:permissions <folder_id> --user <user_id> <path> --test.
To manage the users or groups entitled to set advanced permissions, use occ groupfolders:permissions <folder_id> [[-m|--manage-add] | [-r|--manage-remove]] [[-u|--user <user_id>] | [-g|--group <group_id>]].
To disable the advanced permissions feature for a group folder, use occ groupfolders:permissions <folder_id> --disable.
Group folders can be configured externally through REST APIs.
The following REST API's are supported:
GET apps/groupfolders/folders: Returns a list of all configured folders and their settingsPOST apps/groupfolders/folders: Create a new group foldermountpoint: The name for the new folder
GET apps/groupfolders/folders/$folderId: Return a specific configured folder and its settingsDELETE apps/groupfolders/folders/$folderId: Delete a group folderPOST apps/groupfolders/folders/$folderId/groups: Give a group access to a foldergroup: The id of the group to be given access to the folder
DELETE apps/groupfolders/folders/$folderId/groups/$groupId: Remove access from a group to a folderPOST apps/groupfolders/folders/$folderId/acl: Enable/Disable folder advanced permissionsacl1 for enable, 0 for disable.
POST apps/groupfolders/folders/$folderId/manageACL: Grants/Removes a group or user the ability to manage a groupfolders' advanced permissions$mappingId: the id of the group/user to be granted/removed access to/from the folder$mappingType: 'group' or 'user'$manageAcl: true to grants ability to manage a groupfolders' advanced permissions, false to remove
POST apps/groupfolders/folders/$folderId/groups/$groupId: Set the permissions a group has in a folderpermissionsThe new permissions for the group as bitmask of permissions constants
POST apps/groupfolders/folders/$folderId/quota: Set the quota for a folderquota: The new quota for the folder in bytes, user-3for unlimited
POST apps/groupfolders/folders/$folderId/mountpoint: Change the name of a foldermountpoint: The new name for the folder
For all POST calls the required parameters are listed.
Non-admins can access the GET requests to retrieve info about group folders they have access to.
Admins can add applicable=1 as a parameter to the group folder list request to get the same filtered results of only folders they have direct access to.
Group folders are also exposed through a separate WebDAV API at /remote.php/dav/groupfolders/<user id>.
In addition to browsing the contents of the group folders, you can also request the mount point for the group folder by requesting the {http://nextcloud.org/ns}mount-point property.
