Choosing an archiver: 7-Zip, Bandizip, WinRAR and the rest

All of them open ZIP, 7Z and RAR. The differences are in licensing at work, garbled file names from other countries, what the installer tries to add, and whether you need anything beyond what Windows already does.

First: is the Windows built-in enough?

Windows 11 creates and extracts ZIP in Explorer, and since the late-2023 update it also extracts 7Z, RAR and TAR. If you only occasionally open an archive someone sent you, install nothing. It stops short at password-protected archives, split archives, regional formats such as ALZ and EGG, and archives whose non-English file names come out garbled. If any of those four turns up regularly, pick one of the programs below.

How they differ

7-Zip — open source, the safest on a work PC

Free, no adverts, and no licensing question at a company or public body. Its 7Z format compresses smallest, and it does AES-256 password protection and split archives. In exchange the interface is plain, there is no preview, and it handles archives with garbled non-English file names poorly. It cannot open ALZ or EGG.

Bandizip — the default for a home PC

One of the few archivers whose free edition may also be used at a company (the free edition carries adverts; the paid one drops them and adds repair tools). It detects the code page of archives with garbled file names automatically, opens ALZ and EGG, and lets you preview inside an archive and extract only part of it. Multi-core compression is fast enough to notice on large folders.

WinRAR — the only one that makes RAR

Everyone can extract RAR; only WinRAR can create it. It is paid, with a trial that never quite expires, and it is what turns up in software audits when people assume it is free. Unless you must produce RAR files, there is no reason to buy it.

PeaZip and NanaZip — 7-Zip with a better face

PeaZip is open source with a friendlier interface and many formats. NanaZip is 7-Zip repackaged for the Microsoft Store with Windows 11 context-menu integration. Both are sound choices if 7-Zip’s look puts you off.

Compared where it matters

Garbled file names

ZIPs made on a Mac or by older software in Korea, Japan or China arrive with file names turned into "ã…" and similar. Bandizip detects the code page and usually extracts them intact, and lets you pick one if not. 7-Zip is weak here, so if you receive such files often, keep Bandizip alongside.

ALZ and EGG files

These Korean formats extract with Bandizip; you do not need ALZip for that. Creating them needs ALZip, but since the recipient may not have it, make ZIP or 7Z instead.

Password-protected archives

All of them do it. For an archive anyone can open regardless of program, use ZIP with AES or 7Z. 7-Zip and Bandizip can also encrypt the file names, hiding what is inside.

Packing a large folder quickly

Bandizip and 7-Zip both use every core. At maximum compression 7-Zip’s 7Z comes out smallest; to save time, Bandizip’s fast mode is convenient. In either, the "Store (no compression)" option saves time when bundling already-compressed video and photos.

Work PC

7-Zip or Bandizip. WinRAR only with a purchased licence, and Korean ALZip only with one too. This site’s "Work PC" template includes 7-Zip.

So which one

1. 1

   Home PC, just one → Bandizip or 7-Zip

   Bandizip if you receive files from many sources and want preview and code-page handling; 7-Zip if you want nothing but the essentials and no adverts.

2. 2

   Work PC → 7-Zip (or Bandizip)

   Nothing to check on licensing. If garbled file names are a daily thing, Bandizip is fine too — its free edition is permitted at a company.

3. 3

   You must produce RAR → WinRAR

   The only program that creates it. Buy the licence if it is for work.

4. 4

   If you installed two

   They fight over file associations. Decide which is primary and set the associations in that program’s settings; use the other from the right-click menu when needed.
