The .buc file extension belongs to Adobe Photoshop Elements, Adobe's consumer-oriented photo-editing and photo-organizing software for Microsoft Windows.
A .buc file stores backup data used by Photoshop Elements. It is an application-specific backup file rather than a standalone image file, and Photoshop Elements uses it when restoring backed-up data.
Open or restore a .buc file in Adobe Photoshop Elements on Microsoft Windows. Use the program's backup and restore features rather than trying to open the file as an image.
A .buc file is not normally converted to another format. Restore the backup in Adobe Photoshop Elements, then export any recovered photos or other content to an appropriate standard format if needed.

The BUC image format was associated with ACDSee software from ACD Systems and contains image data that could be viewed by ACDSee Photo Manager.
BUC is a legacy format associated with older versions of ACDSee for Microsoft Windows. The format appears obsolete and is not supported by current versions of ACDSee.
Open the BUC file with a compatible version of ACDSee Photo Manager on Microsoft Windows. Current ACDSee releases may not recognize this legacy format, so an older installation may be required.
If a compatible version of ACDSee can open the file, use its image export or save function to create a common format such as JPEG or TIFF.
