Corel Presentations slideshow (.shw)

.shw file signature | application/x-corelpresentations

Corel Presentations slideshow (SHW) is a presentation file format created by Corel for its Corel Presentations software, part of the WordPerfect Office suite. It is used to store slide decks for business presentations, training materials, and other on-screen presentations, and was opened and edited in Corel Presentations and related office suites. The format is now largely legacy and may not be supported by modern presentation applications, so files from untrusted sources should be handled with usual caution.

Validation Code

How to validate .shw files in Python

Python
def is_shw(file_path: str) -> bool:
    """Check if file is a valid SHW by magic bytes."""
    signature = bytes([0x52, 0x49, 0x46, 0x46])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .shw files in Node.js

Node.js
function isSHW(buffer: Buffer): boolean {
  const signature = Buffer.from([0x52, 0x49, 0x46, 0x46]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .shw files in Go

Go
func IsSHW(data []byte) bool {
    signature := []byte{0x52, 0x49, 0x46, 0x46}
    if len(data) < 4 {
        return false
