Citrix Virtual Computer Lab (VCL)
Note: The VPN is required to access the VCL from Off Campus
For more information, please visit this ask article.
The maintenance window for the VCL is Tuesday mornings from 5-7 am. Expect disruptions and outages during this time frame as we do our best to keep our technology up to date.
The VCL leverages software provided by Citrix to perform its tasks, so that the required resources are handled by our servers and not your computer. This allows more widespread access to resource-intensive programs on a wider variety of computer hardware than would otherwise be possible.
Getting Started
We recommend updating your installation of the Citrix Workspace App before every semester for the latest performance enhancements, security updates and bug fixes. If you are still running Citrix Receiver (replaced by Workspace App), please upgrade now!

VCL Software List
Saving Files to Your Personal Computer
- Save in \\\\Client\\C$(location will vary depending on the application you’re using). You cannot save to the C: drive on the VCL application host servers. On Windows, \\\\Client\\C$ is the root directory of your client computer. On a Mac, \\\\Client\\C$ is your Mac Home folder. In some applications, we map a V: to \\\\Client\\C$ since they do not handle the UNC mapping well. You may also be able to save to a USB, if your USB is the E: drive, then \\\\Client\\E$

- The Documents folder on the VCL is redirected to your personal space on our files server, the U drive
Saving Files to VCL Server User Folder (U)
An option to save to a user folder on a VCL server share. Your folder will be mapped as the (U:) drive.
- 2 GB storage per user, saved files available to you in future sessions (automatic increases up to 10GB in 2 GB increments, updated daily based on usage)
- Available via Secure FTP, such as WinSCP on Windows or Cyberduck on a Mac (click the link under "Download" for the free version of Cyberduck), hostname: vclfs.eng.umd.edu Use SFTP setting or specify port 22
- Significantly better performance with applications that use a lot of disk I/O
- Alternative if you are having an issue saving locally, or some applications which have issues saving locally such as Cadence

Saving Files to TERPDrives/Kumo Cloud Storage
This service will map a Windows drive in your VCL or computer lab session to any cloud storage spaces you authorize (Box, Google Drive, DropBox, OneDrive). You control what cloud storage services to connect to, if any. To do so, go to kumo.umd.edu and authorize which cloud services you would like to use when using the VCL and computer labs. Then, when launching applications in the VCL, those drives will be mapped as in the image below.

Thanks to DivIT for offering this service.
Saving File to USB, External Hard Drives, and Your iPad
On many applications, you will be able to save to other drives on your client machine, such as a USB device or additional hard drive.
Saving locally to your iPad from the Citrix Workspace for iPad app
- Save locally just as you would do from a typical VCL session from a PC or Mac. The local iPad storage may show up as \\\\Client\\C$(V:) or Local Disk (C: on <iPad name>), depending on the app.
- When you first attempt to access this location, you will be prompted to grant access to Citrix Workspace. Select "Read and write access".
Logging Out
Windows
In most cases, exiting an application will close your session; however, closing some applications (such as Creo Parametric and Cadence) doesn’t always fully end your session properly. If you are having trouble running an application you recently closed, your session may not have fully terminated.

- Right-click on the Citrix icon in the icon tray (^ Up arrow) in lower right-hand corner of the screen.
- Choose Connection Center.
