Corel makes a .BAK backup file that has the same name and is usually located in the same folder as the original file, but can also be located in the /Programs/Corel/Programs/Draw folder.

When a file is corrupted or otherwise damaged, find the .BAK file, open it, and copy it (save as) over the original corrupted file.

Good luck!
