Frequently Asked Questions
What file formats can the viewer detect?
Detects common formats including PNG, JPEG, GIF, PDF, ZIP, EXE, ELF, Java class files, and many archive formats based on magic numbers and file signatures.
How does file structure analysis work?
The tool parses known file formats (like PNG chunks or JPEG markers) to show the internal structure, helping understand how the file is organized.
What is entropy analysis and why is it useful?
Entropy measures randomness in data (0-8 bits). High entropy suggests encrypted/compressed data, while low entropy indicates structured or repetitive content.
Can I view large files without performance issues?
Yes, the tool limits display to a configurable number of bytes (default 64KB) and supports offset viewing to inspect specific file sections efficiently.
How do I interpret the different display modes?
Hex shows bytes as hexadecimal, binary shows bits, ASCII shows printable characters. Combined mode shows all three for comprehensive analysis.
