Frequently Asked Questions
What is a .lep file?
A .lep file is a LEP file. Leptoncompressed JPEG image[68]
What are the magic bytes for .lep files?
The magic bytes for LEP files are CF 84 01 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .lep file?
To validate a .lep file, read the first bytes of the file and compare them against the known magic bytes (CF 84 01) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .lep files?
There is no officially registered MIME type for .lep files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .lep files?
LEP (.lep) 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.
