Frequently asked questions
What is a .bz2 file?
A single-file compression format offering higher compression than gzip at the cost of slower speed.
Can I edit a .bz2 file?
Not directly as text — .bz2 is a runnable or packaged format, not one meant for manual editing.
Does having a .bz2 extension mean the file is safe?
No single extension can guarantee that. Archives can contain any type of file, including executables or scripts, inside them. Check what's inside — ideally with an up-to-date antivirus scan — before opening extracted contents. Always consider where the file came from, not just its name.
