How to Open ASD File after Unsupported File Type Error?

“On my system, Word application stopped responding all of a sudden. So, I immediately saved the document, which I was working and then closed the Word application. But the file is saved with .asd extension, instead of .doc. Also, if I try to open the file I get an error that states, “Microsoft Word cannot open this file because it is an unsupported file type.” What is this ASD file? How can I recover contents of my Word document? Someone kindly help me.”

What is ASD or .asd file?

Before you know about ASD file, have knowledge of AutoRecover feature provided in Microsoft Word program.

Still, it is not an alternative for Save option. So, AutoRecover aspect aids in safeguarding a Word file during sudden disaster, only if the file is saved throughout the process as well at end.

If Word is terminated/interrupted in middle of process, then the current document will be saved in AutoRecover folder (if it was saved frequently, also at end); only when AutoRecover option is enabled. You can find AutoRecover folder under this path- C:\Users\AppData\Roaming\Microsoft\Word\ (Windows 7 and above) and C:\Users\Application Data\Microsoft\Word\ (Windows 7 and below).

And Auto-Recovered file will be named as

  • AutoRecovery save of X.asd (X is name of opened file) in Win 7 and below
