Virtual Drive and PADS4 Servers
Here’s a more professional and polished version of your text:
Upgrading to PADS4 Version 2021.3 and Higher
With the release of PADS4 version 2021.3, a new Advanced Content Library System has been introduced. This update enhances functionality and security by transitioning from an open folder structure to a controlled environment. As a result, existing installations may require minor adjustments to accommodate this change.
PADS4 Advanced Content Library
Starting from PADS4 version 2021.3, the content library is no longer stored within the traditional directory path:
Instead, it is now managed within a closed environment, enabling PADS4 to introduce advanced features and improved security while maintaining seamless content management.
PADS4 Virtual Drive on PADS4 (Sub/Backup) Servers
When using PADS4 Designer, Data Folder Data Providers, PADS4 CMS, or PADS4 Workspace, the system now utilizes a Virtual Drive as a gateway to the new closed content environment.
For existing installations that rely on the traditional Content Library folder, compatibility is maintained through this mechanism. The Virtual Drive is automatically installed during the upgrade process.
Performance Considerations
Users may experience a slight change in performance, as the Virtual Drive retrieves content dynamically from the closed environment instead of a direct file system structure.
How Does It Work?
When installing PADS4 Server version 2021.3 or higher, a Virtual Drive Service is automatically deployed. This service provides seamless integration with the new Advanced Content Library.
Navigating the Virtual Drive
After upgrading, you may notice that the previous content library folder:
is now represented as a Virtual Folder (indicated by an arrow on the folder icon). You can still open and interact with it as you would with a normal folder.
Functionality
Although the folder appears to contain files, no actual data is stored locally. Instead, the system dynamically retrieves and displays file information from the PADS4 Server. Users can:
- Add, edit, and delete files
- Open files for editing and save changes directly
- Synchronize changes automatically with the PADS4 Server
Additionally, any new files uploaded via the PADS4 Web Portal will appear in the Virtual Drive folder.
Log File Location
For troubleshooting and log analysis, the Virtual Drive Service maintains a dedicated log file. You can find it here:
API for Content Management
With PADS4 version 2021.3, a new Content Management API has been introduced, replacing the previous Agent SDK. This API provides improved functionality and flexibility for managing content programmatically.
For further details and implementation examples, refer to the PADS4 API Documentation on GitHub.
Content Library and Viewers
The mechanism for syncing Viewers remains unchanged in this update. Existing processes for content synchronization and playback will continue to function as before.
