What's the difference between iZip and iZip classic?

iZip classic's code originates from 2010 and while we've been regularly updating it to maintain compatibility with newer versions of macOS, it is no longer feasible for us to do so.

The major maintenance issues with iZip classic are maintaining backwards compatibility with 10+ year old operating systems while constantly updating for modern versions of macOS, and iZip classic's reliance on kernel extensions (which are gradually being made harder to load and work with each new iteration of macOS) to emulate removable disks.

"iZip" (v4 and above) is the current, modern version of iZip that has been completely re-written in 2022 with a focus on speed, reliability, future-OS-compatibilty and support for the most common modern archive formats (e.g RARv5, 7ZIP, etc). This is the recommended variant you should install if your Mac can run macOS Monterey 12.4 or above. This version is also about half the size of iZip classic while natively supporting machines with either Intel 64bit or Apple Silicon processors (M1, M1 Pro, M1 Ultra, M2). This latest version of iZip no longer makes archive contents available system-wide by emulating removable storage. We're sad to see this feature go but unfortunately it was no longer tenable. The upside is that removing this allows us to focus on making iZip even better by having a quicker release and update schedule. We have a lot of interesting things planned for iZip that we can now concentrate on instead of low level OS compatibility.

Registration

If you've registered iZip, thank you!

Make sure you open the ZIPX registration archive we sent you *with* iZip and not the built-in OS unarchiver.

In case the file type associations to iZip are not yet set, you might need to save the ZIPX from your email program and then open the iZip app, click 'Open' and navigate to the file you saved.

You should also open the ZIPX registration file using the same Mac or PC you purchased on.

Other "iZip" products

You should only ever click a download link for iZip from www.izip.com or www.izip.com/windows

Any iZips you find on the Google Play Store are NOT developed by us, they are simply using our name. The software we provide here at iZip.com was the first to use this name. Please don't support others trading off our goodwill.

If you find iZip useful, please purchase a license by clicking Upgrade in the app. This helps us fund continued development.

Sharing iZip created archives

The iZip archive Wizard creates modern archives with full unicode support and optional AES-256 encryption.
Most modern operating systems support these types archives with their built-in bare-bones decompressors. When sharing encrypted ZIP files, please make sure to use a strong password. Recipients running an older OS may need to download iZip or another up-to-date alternative like WinZip/WinRAR/7Zip/iZip for Windows.
iZip is a free download so please tell your contacts to use it too! :)
Built-in file sharing is currently disabled because iZip is no longer associated in any way with files dot com.
