SHB (.shb)
.shb file signature | application/octet-stream
SHB is a legacy background file format created and maintained by Corel for Corel SHOW! 5.0 presentation software. It was used to store slide or screen background graphics for show documents and related presentations. The format is obsolete and generally safe, though files from old software may not open in modern applications without conversion because support has largely been discontinued.

Frequently Asked Questions
What is a .shb file?
A .shb file is identified by the magic bytes 52 49 46 46 73 68 62 35 at byte offset 0. SHB is a legacy background file format created and maintained by Corel for Corel SHOW! 5.0 presentation software. It was used to store slide or screen background graphics for show documents and related presentations. The format is obsolete and generally safe, though files from old software may not open in modern applications without conversion because support has largely been discontinued.
What are the magic bytes for .shb files?
The magic bytes for SHB files are 52 49 46 46 73 68 62 35 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .shb file?
To validate a .shb file, read the first bytes of the file and compare them against the known magic bytes (52 49 46 46 73 68 62 35) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .shb files?
There is no officially registered MIME type for .shb files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .shb files?
SHB (.shb) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
