Compression Info

Use this dialog box to view the following information about the selected compressed drive. The graphic illustrates how much space is used on your compressed drive relative to how much disk space is free. The information at the top of the dialog box displays the name of the file that contains the compressed drive.

Caution: Do not delete the file that contains your compressed drive. Doing so might result in loss of data.

Choose one of the following buttons for information about the dialog box:

 Space Used

 Space Free

 Total Space

DoubleSpace Info
Space Used

The Space Used field shows the amount of data stored on the compressed drive. (This is the amount of space that the same data would use if it were stored on an uncompressed drive.)


DoubleSpace Info
Space Free

The Space Free field displays an estimate of the free space on the drive. The acutal amount of data you will be able to store in this space depends on how compressible your files are. The estimated compression ratio is used to estimate the free space.


DoubleSpace Info
Total Space

The Total Space field shows an estimate of the drive's total capacity. This number is the sum of the Space Used and Space Free.

Show Details Button

Choose the Show Details button to display the names, sizes, and compression ratios of the files on your compressed drive. The compression ratio is the relative size of the compressed file to the size of the same file when uncompressed. For example, if the compression ratio of a file is 1.8 to 1, the compressed file takes up 1 byte for every 1.8 bytes the file would use if it were uncompressed.
