Workflow Automation

FileCloud's Workflow Automation functionality, available in the user portal, enables end users to automate the steps in business processes. For example, the creation of a marketing document could trigger a process that moves it through a series of departments for approval, or a value in a form could determine which users it is shared with.

All of this is completed in a simple drag and drop interface where variables such as email addresses and folder names are easily filled in for each action. After workflows are created, users can track them in a dashboard that shows when they are running and when runs are complete.

Automated Workflow 

See Workflow Automation and Automated Workflow Management.

MS Teams Integration 

FileCloud now integrates with MS Team.

Users are able to log into FileCloud to access and share their content while working in the messaging component of MS Teams. Each share link is automatically inserted into an MS Team message that can be sent to share recipients. 

In addition, users can log into a full view of the FileCloud user portal while in MS Teams, and use its full features as they would outside of Teams.

See Integration with MS Teams and Microsoft Teams.

Compliance Center for ITAR

You can use the new Compliance Center to measure how ITAR compliant you are and to get help fixing your compliance issues. The tool examines your settings for DLP rules, metadata sets and encryption and uses them to determine whether or not you meet specific regulations. If you do not meet a regulation, you can follow instructions for to make your system compliant, or, in some cases, you can change settings directly from the Compliance Center.

See Compliance Center

Desktop Edit

FileCloud's Desktop Edit client enables users to edit files from the user portal in their native applications, and automatically uploads the edited versions of the documents so updates are immediately reflected in the user portal file. Users must open the Desktop Editor by logging in to it, and are then able to click the Edit in [native application] link for any files of types that can be opened in the editor.

Online Onboarding

The trial installation of FileCloud Online includes new sample files in My Folders, Team Folders, and Shared with Me to help you get started. With the welcome email, users are given a username and password of an Admin user that they can use to log in to the end user and Admin portals.

Sample components for online onboarding

See FileCloud Online Quick Start Guide

Group Management

Now, Admins can enable users to create their own user groups and share content with them. When an Admin enables the feature, users can choose Manage User Groups in the User drop-down list. This opens a dialog box that enables them to add, edit, and manage user groups.
For a user to perform a User Group action, an Admin must enable the action in the user's policy. Admins have the ability to edit and delete user groups, and to assign users as administrators to them.

See User Groups and Group Settings.

OnlyOffice Integration

FileCloud's Web Edit feature now supports OnlyOffice for editing docx, pptx and xlsx files. After a FileCloud Admin configures the Web Edit settings, when users who have installed OnlyOffice edit documents, the files are automatically opened in OnlyOffice.

DLP Admin UI

The DLP Admin user interface has been updated with a new interface that simplifies the process of creating rule expressions with a wizard that enables you to choose from valid expressions instead of manually entering them.

See Creating Data Leak Prevention Rules.

Standalone File Browser

FileCloud's standalone file browser functions similarly to Windows Explorer and Mac OSX Finder. Users can use the this file browser as an alternative to the user portal to view, share, edit, and delete all files on the server. FileCloud features such as desktop edit, advanced search, and manual locking/unlocking of files are available.

See FileCloud File Browser.

File Action Approval

Users can now request approval of file actions by right-clicking on a file and choosing Send for Approval. They are prompted to enter a recipient and a message about the request, and the recipient is notified of the pending request.

When the recipient logs in to the user portal, they can see the notification and access their Actions screen, which lists file approval requests they have received and sent. When the recipient approves or rejects the request, the requestor can see the status change by going to their Actions screen and clicking the Sent tab.

If users are marked as approvers in Automated Workflows, they can also view and approve or reject file and share approval requests sent from workflows in their Actions screens.
