Creating Larger Capture Disk For Use With App Volumes Command-Line-Capture Program


While administering End User Computing environments, it is sometimes necessary to have more than 10GB of space for creating packages for VMware App Volumes. This tutorial provides the required steps to create different sized capture disks when using the App Volumes Command-Line Capture program.

Purpose of This Tutorial

This tutorial takes you through the steps to change the capture disk size for the App Volumes Command-Line-Capture Program. Before you change the size of this disk, you must first set up an Install App Volumes Application Capture Command-Line Program. For more information, see the VMware App Volumes documentation.


This tutorial is intended for IT administrators and product evaluators who are familiar with VMware App Volumes. Familiarity with networking and storage in a virtual environment, Active Directory, directory services is assumed. Knowledge of other technologies, such as VMware Horizon is also helpful.

Create Your Capture Disk

When capturing App Packages, you may find that some applications require more disk space than can be provided with the default template. The App Volumes Command Line program gives you the ability to create new templates with the required space.

Note: The steps are sequential and build upon one another, so make sure that you complete each step before going to the next step.


Before you begin, make sure you have installed the App Volumes Command-Line Program.

Creating Capture Disks

  1.  Log in to the capture machine.
  2. Create new VHD of desired size in the C:\Program Files (x86)\VMware\AppCapture\templates\ with a name of wemcapture_[newsize].vhd.

    2. Click Show hidden files and folders to open the Folder Options window.
    3. Select Show hidden files, folders, and drives.
    4. Ensure that these options are not selected:
      • Hide empty drives in the Computer folder
      • Hide extensions for known file types
      • Hide protected operating system files (recommended)

  8. On the newly created VHD, do the following:
    1. Using diskmgmt.msc, unassign the drive letter and unmount the VHD.
    2. Set attribute NODEFAULTDRIVELETTER for the volume.

  9. Shut down the capture VM and create a new snapshot.
  10. Rename the original template and name the new one wemcapture:

You are now ready to use the new, larger template to capture applications!
