The blk file extension is associated with Corel WordPerfect Office, an office suite for Microsoft Windows developed by Corel Corporation.
BLK files store temporary working data used by the suite. They are supporting files rather than user documents and are not intended for long-term storage or file exchange.
Corel WordPerfect Office creates and manages blk files automatically on Microsoft Windows. They are not intended to be opened directly by the user.
If a blk file remains after the suite has closed, it may be associated with a previous operation. Open the original document with WordPerfect Office instead of opening the temporary file.
A blk file cannot normally be converted meaningfully because it contains temporary data rather than a user document.
To create a convertible file, open the original document in Corel WordPerfect Office and use the suite's save or export function to choose an appropriate document format.
