Frequently Asked Questions

How much memory does 7z extraction need?

LZMA2 decompression memory depends on the dictionary size used during compression. Typical: 16–64MB RAM. High compression: up to 1.5GB. This file uses standard settings (~32MB RAM for extraction).

Can 7z archives be split into parts?

Yes. 7-Zip supports multi-volume archives (.7z.001, .7z.002, etc.). Use the 7z command-line tool with -v option to create split archives: 7z a -v10m archive.7z files/

Does 7z support encryption?

Yes. 7z uses AES-256 encryption and can encrypt both file content and file names (unlike ZIP which leaves filenames visible). This makes 7z one of the most secure open-source archive formats.
