Actually, if you go look at the web page https://www.solvusoft.com/en/file-extensions/file-extension-qic/ and also https://www.solvusoft.com/en/file-extensions/software/microsoft-corporation/microsoft-windows-backup-utility/ you will find out much more about the .QIC file format which was created NOT ONLY by Roxio's backup program but ALSO the MICROSOFT WINDOWS BACKUP UTILITY.
Furhermore, you can see/learn more about THE PURPOSE of USING WINDOWS BACKUP if you go to Microsoft's OWN WEBPAGES at https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms851494(v=winembedded.11)?redirectedfrom=MSDN and https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms851487(v=winembedded.11) .
So, NOW Microsoft NO LONGER SUPPORTS accessing/RESTORING the DATA BACKUP FILES that its OWN PROGRAM created and that it PUSHED for YEARS as being THE WAY TO ENSURE DATA PRESERVATION? What the hell kind of DATA SECURITY IS THAT???
Microsoft wants users to TRUST THEM with their data, but then it DOESN'T SUPPORT RESTORING the data??? There is NO PLAUSIBLE EXCUSE for that! THAT IS UNACCEPTABLE!! I am TOTALLY PISSED OFF at Microsoft, both AS A USER and, even moreso, AS A SHAREHOLDER! It TELLS THE USERS THAT MICROSOFT CAN **NOT** BE RELIED UPON TO ASSIST THE USERS WITH THEIR DATA INTEGRITY!
