SYMPTOMS
========
When you use the DIR /C or DIR /CH command on a volume that is compressed with
DriveSpace 3.0, a compression ratio may be returned for files that have not been
compressed. The ratio may be as high as 64:1.
CAUSE
=====
The DIR /C command displays the compression ratio of a file, assuming that the
file is located on a drive using 8K clusters. This command returns an estimated
compression ratio for all files, regardless of their compression status, as if
they were compressed on a drive with 8K clusters.
The DIR /CH command may return a more accurate value if the cluster size is not
8K, as it references the cluster size of the host partition for its estimates.
However, this command also returns an estimated compression ratio for all files
saved to the drive.
MORE INFORMATION
================
Microsoft Plus! for Windows 95 installs DriveSpace 3.0 and System Agent by
default unless you choose not to.
You can save uncompressed files to a compressed volume when the No Compression
option is selected for the drive.
You can configure the Compression Agent with System Agent to compress the files
at a later time. This configuration maximizes system performance by delaying the
compression of files written to the drive until the computer is idle.
STATUS
======
Microsoft has confirmed this to be a problem with Microsoft Plus! for Windows
95. We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
