|---|---|
| File Extension | .wbk |
| Proprietary Format | The WBK extension is a proprietary backup format created by Microsoft for its Word application, specifically prevalent in Word versions up to 2003. |
| Dependency on Primary File | While it is a standalone file, its existence and purpose are intrinsically tied to an active parent Word document (.doc). |
| Loss Prevention Focus | Its sole, critical characteristic is to prevent data loss, acting as a simple but effective recovery solution. |
| Compatibility | WBK files are designed to be opened directly with Microsoft Word. Newer versions of Word (2007 and later with .docx) may still support opening older .wbk files but typically use different automatic backup systems. |
| Manual Recovery Process | Unlike cloud-based auto-save features in modern software, recovering from a WBK file requires the user to manually locate and open the backup copy. |
