When the image package is updated and merged for many times, the image files are becoming bigger and bigger. So what to do when it gets big.

1. The first method is to upload the image again.

In new version of CCBoot from 20160405, uploading image is much easier. Now, you dont have to tick the "Enable Upload image" in clients. Just open CCBoot client application and click upload, it's just that easy, now.
Follow the steps below to upload a new image from your older big image.

1) Diskless boot one of the PC, Example "PC101".

2) In PC101, run the CCBootClient.exe program.

3) It will pop up the "CCBoot Client" dialogue box, enter the CCBoot server IP address in the "Server IP Address" edition box, and enter a new image file name in the "Image File Name" edition box, and enter the new image size. For now 100GB, and then click the "Upload Image" button  (Figure 1).

4)  It will ask you to enter password, just enter the password you set in the CCBoot Server UI.

5) Once the upload is complete the new image file is a smaller than your previous image file.

2. The second method is to use GHOST software, to copy over the image again.

The following operations are needed in the Win2008 operating system. The specific steps are as follows:

1) Firstly you need to take the "Merge Image" operation for the image which needs slimming. For details, please refer to "How to Merge Image".

2) Assume the name of the image file which needs slimming as XP.VHD

3) Copy the XP.VHD, named OLD.VHD.

4) Open the "Server Manager" window, expand the "Storage" node, right-click the "Disk Manager", click the "Attach VHD" (Figure 1‑5).
