Version History:

Superceeds MS-DOS® 3.30 through 6.00 as an in-place upgrade of an existing operating system. Like the base release of 6.20, this upgrade included the new data protection features Microsoft® Corporation integrated into DBLSPACE after problems with data loss in the early release of the compression utility. Parallels the base release in function and file set.
