(All versions, all products)

To Whom It May Concern

Diskeeper for Windows, Diskeeper Lite for Windows, Undelete for Windows; and Diskeeper, I/O Express, Filemaster and Frag Guard for Open VMS Operating Systems operate now and will continue to operate as Year 2000 Compliant Products. There are no known date-related problems with any of these products. Each of these products is Year 2000 and leap year compliant on their past and current release versions and will remain so.

Specifically, our OpenVMS products operate on standard date and time conventions on the OpenVMS operating system. This has been tested in-house. The OpenVMS operating system handles standard date and time functions with a four (4) digit year field, as YYYY-MMM-DD.

There are no yearly date functions applicable with Diskeeper for Windows. Scheduling is set by the hour, day or week, and has been successfully tested for Year 2000 compliance. There are no yearly date functions applicable with Undelete for Windows.

Our products on the OpenVMS and the Windows Operating Systems:

• Can be used prior to, during and after the calendar year 2000 without error relating to date data;
• Will not abnormally end or provide invalid or incorrect results due to date data, especially between centuries;
• All calculations and logic of time-related data (dates, duration, days of week, etc.) will produce the expected results for all valid date values within the applications;
• Calculations and logic include sort algorithms, calendar generation, event recognition, and all processing actions that use or produce date values.
• For any date element represented without century, the correct century is unambiguous for all manipulations involving that element, and, the meaning of dates presented in reports and screens are unambiguous.

If you have further questions please feel free to contact our Tech Support staff at your earliest convenience.
