Open ZIP, RAR, 7Z, ZST and More on Mac

Someone sends you a ZIP file.

A software download arrives as 7Z. A backup ends in .tar.zst. An older project is stored in several RAR parts. The next archive requires a password.

You did not choose any of these formats.

You just need the files inside.

The format should not become your problem

Different archive formats serve different purposes.

ZIP offers broad compatibility. RAR and 7Z are commonly used for compact multi-file archives. TAR preserves complete directory structures, while GZ, XZ, ZST, and LZ4 provide different combinations of compression ratio and speed.

Those differences matter when creating an archive.

When opening one, the goal is always the same:

Extract the archive and get the files.

You should not have to research every unfamiliar extension, install another command-line utility, or keep a collection of format-specific extractors on your Mac.

One consistent way to extract archives

unpackALL handles the major archive and compression formats through one simple interface.

It supports:

• ZIP
• RAR
• 7Z
• TAR
• GZ and TAR.GZ
• BZ2 and TAR.BZ2
• XZ and TAR.XZ
• ZST and TAR.ZST
• LZ4 and TAR.LZ4

Drop one or more archives onto the app. unpackALL detects the format, extracts the contents, and places the resulting files beside the original archive.

There are no extraction profiles to configure and no format-specific tools to select.

When an archive contains another archive

Some filenames contain two extensions:

backup.tar.gz
dataset.tar.xz
package.tar.zst

These files have two layers.

TAR bundles the original files and folders into one archive. GZ, XZ, or ZST then compresses that TAR file.

Extracting only the outer layer leaves an intermediate .tar archive:

package.tar.zst
        ↓
package.tar
        ↓
package folder

unpackALL can recognize that inner TAR archive and continue automatically. Instead of stopping halfway, it extracts the final files and can remove the intermediate archive afterward.

Multipart archives behave like one archive

Large RAR and 7Z archives are sometimes divided into several files:

backup.part1.rar
backup.part2.rar
backup.part3.rar

These are not independent archives. Each file contains part of the same data.

unpackALL recognizes multipart archives and combines the segments during extraction. Open the first part and the app locates the remaining pieces.

Password-protected files

Password protection is common for private documents, customer files, backups, and restricted downloads.

When an archive requires a password, unpackALL asks for it during extraction.

The archive remains on your Mac. Nothing is sent to an online extraction service, and confidential files do not need to be uploaded simply because macOS cannot open their format.

Open archives directly from Finder

Drag and drop makes it easy to process several archives at once, but unpackALL can also become the default application for supported archive formats.

After the Finder association is configured, opening an archive becomes the familiar Mac workflow:

Double-click. Extract. Done.

It does not matter whether the next file is a familiar ZIP or one of the other major compressed archive formats.

You need the contents, not another utility

The developer, backup service, download site, or colleague creating an archive decides which format you receive.

You should not need a different workflow for every decision they make.

unpackALL opens ZIP, RAR, 7Z, ZST and other major archive formats on macOS.

No Terminal commands. No cloud upload. No format hunting.
