Expanding a drive to remove compression

If you later decide that you no longer want to compress a drive, you can remove compression from the drive. However, before you do this, you should ensure that the drive has adequate free space to accommodate the expanded files. Typically, you'll need at least 50 percent more free space on the disk to expand its contents successfully. If a compressed disk currently uses 40 GB of space, this means you'd probably need about 20 GB of free space to expand the disk successfully.

You can expand a disk by completing these steps:

1. In Windows Explorer or Disk Management, right-click the drive that contains the disk that you want to expand and then select Properties.

2. On the General tab, clear the "Compress drive to save disk space" checkbox and then click OK twice.

3. In the Confirm Attribute Changes dialog box, shown in Figure 19-18, specify whether you want to expand only the top-level folder of the drive or the entire drive:

• To expand only the drive's top-level folder, select "Apply changes to drive X:\ only."

• To expand the drive's top-level folder, subfolders, and files, select "Apply changes to drive X:\, subfolders and files."
