Frequently Asked Questions
What is a .lbm file?
A .lbm file is a LBM file. IFFInterleaved Bitmap Image
What are the magic bytes for .lbm files?
The magic bytes for LBM files are 46 4F 52 4D 49 4C 42 4D at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .lbm file?
To validate a .lbm file, read the first bytes of the file and compare them against the known magic bytes (46 4F 52 4D 49 4C 42 4D) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .lbm files?
There is no officially registered MIME type for .lbm files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .lbm files?
LBM (.lbm) 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.
