DIR /C Fails to Report File Compression Ratio (103544)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.0
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q103544
SUMMARY
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
and filenames.
The DIR /C command does not report a compression ratio for a file if
one of the following is true:
• The Microsoft DoubleSpace FAT (MDFAT) is damaged.
• The file is open in another Windows virtual machine (VM), and the
MDFAT has not been updated.
• The file was created by Microsoft Backup (or Microsoft Backup for
Windows).
To work around this problem, check the file compression ratio in File
Manager or run ScanDisk.
NOTE: The fact that a file does not have a compression ratio does not
affect the ability of DoubleSpace to calculate an actual compression
ratio (ACR) for the whole drive.
