Mailfence Documents: secure file sharing, storage and collaboration

Mailfence strives to make the internet a safer place. That’s why we developed our encrypted email solution. But in our opinion just offering secure and private email is not sufficient. Otherwise our users would need to use insecure solutions to manage their appointments, create and store their files or chat online. That is why Mailfence is much more than secure email. Mailfence allows you to organize your life through powerful productivity tools such as Mailfence Calendar, Mailfence Documents, Mailfence Contacts, Mailfence Groups, Mailfence Chat and Mailfence Polls. Therefore in this post you will discover how to store, share and collaborate on files with Mailfence Documents, our secure file sharing solution.

How can I use Mailfence secure file sharing application to collaborate with colleagues, friends and family?

You can use Mailfence Documents secure file sharing both to share files with other Mailfence users, but also with contacts that do not use Mailfence.  To collaborate with other Mailfence users you need to be member of the same Mailfence Group.  Learn here how to create Mailfence groups.

1.  How to access Mailfence group files

In order to access group files, use the pulldown menu under the logo at the left top of the screen and select the group.  The default value of the selector is ‘Private’ (which is your personal documents).

2.  How to manage access rights for group documents

To manage rights do a right click on the document or folder and choose ‘Access rights’.

  • All group members may always view group folders and documents. In other words, they always have the Read right.
  • Group administrator and co-administrators may always add and delete content (i.e. folders and documents).
  • Group administrators and co-administrators can give the Add content and Add and delete content right to some or all members. Note: The Add content right also allows to rename folders.
  • Also, a document creator may always edit it.
  • Creators of documents can also give additional rights to some or all members.  The document Edit right allows to change its contents but also its meta-information (name, etc.)
  • Note: Each folder has its own access rights. Furthermore you can easily apply the same rights to the subfolders by clicking on Apply to subfolders. Please note that if you change the folder rights, they won’t be applied to subfolders automatically. You’ll have to click on Apply to subfolders if applicable.

3.  How to add data to group documents

Click on ‘+ New’ in the top menu of the Documents tool.

  • Content can only be added in the current folder only if the group administrator has allowed you to.
  • You can also create a subfolder and upload documents within.

An alternative approach is to share private data (i.e. a document) with a group. The item will be visible in the group while remaining also in your private environment:

  • There is only one item: all edits made in your private environment will be visible in the group and conversely.  This avoids creating duplicates (which can end up with different contents).
  • To share an item with a group, you must have been granted the right to Add content in it.
  • Also, a single item may be shared with several groups.
  • Select a private item and choose Share with groups in its Actions. Click on the Share button. Then, choose a group and a destination folder within this group. If the item is a Document, create the destination folder if necessary.
  • If you don’t want to share this item anymore, go to the same screen and click on the icon (Remove) next to the group name.

4.  How to notify group members

When creating or editing a group document, you can send an email notification to all group members (except yourself) to let them know that a new document (or a new version of a document) is available. However, this standard notification can be personalized with your own comments.
Note: Only the document creator may send a notification.
  • To send a notification, select Notify by e-mail in the Actions menu of the document.

Online edition

With Mailfence Documents secure file sharing you don’t need Office software (Microsoft Office, OpenOffice) installed on your computer anymore to be able to edit word processing, spreadsheets and presentations documents. In addition, Mailfence Documents integrates an online editor which offers the main features.

This editor is available if you have the right to edit a specific Document.

Select Edit online from the contextual menu of an “Office” Document. To save your changes, click on the “Save” button in the online editor.

Documents in a group can be edited by several people at the same time, each user editing a paragraph at a time. Edits made by others are displayed in real time. A chat is also available.

Note: The online editor is presently provided by a third-party application, which will access your edited Documents contents.  We therefore cannot guarantee the privacy of online edited documents.  We do plan to release a new online editing tool hosted on our own secure servers soon.

Virtual drive: access via Webdav

1.  What is a virtual drive

The virtual drive allows you to access your documents directly (without a Web browser): documents are in a special folder on your computer, protected with a login and a password.

This folder acts as a standard folder: you can add, delete and/or rename files and subfolders. You can also open a file from the folder or from an application on your computer. The virtual drive is also an easy way to back-up the files stored on your personal computer.

2.  How to create a virtual drive

The procedure depends on your operating system. For instance, our online help gives a detailed step-by-step guide for every operating system.

You will notice that the virtual drive consists of different folders:

  • A ‘private’ folder: it contains your private folders and documents
  • A folder for each group: each folder contains group folders and documents

Note: All documents must be stored in one of these folders: you may not place documents or create new folders on the top level.
