Frequently Asked Questions
What is a .wsc file?
A .wsc file is a Windows Script Component file. Windows Script Component (UTF-8)
What are the magic bytes for .wsc files?
The magic bytes for Windows Script Component files are 3C 3F at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .wsc file?
To validate a .wsc file, read the first bytes of the file and compare them against the known magic bytes (3C 3F) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .wsc files?
There is no officially registered MIME type for .wsc files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .wsc files?
Windows Script Component (.wsc) 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.
