Frequently asked questions
What is a .gz file?
A single-file compression format common on Unix/Linux systems, frequently used to compress a .tar archive (see .tar.gz) or a single log/data file.
Can I edit a .gz file?
Not directly as text — .gz is a runnable or packaged format, not one meant for manual editing.
Does having a .gz 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.
