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.



SYMPTOMS
When using MS-DOS DoubleSpace with Windows NT configured for Dual Boot, you cannot see your compressed files or run your MS-DOS-based programs when running MS-DOS Prompt under Windows NT.



CAUSE
To accomplish disk compression, DoubleSpace uses a device driver (loaded at system startup) to intercept disk reads and writes from the command line and MS-DOS-based applications. When you run MS-DOS Prompt under Windows NT, the DoubleSpace device driver is not loaded.

Additional query words: 6.0 6.20 dblspace double space
