A Macintosh archival compression program, similar to StuffIt but using its own compression algorithm (.cpt). It could also create self-extracting archives (.sea) and read/write .hqx and .bin files for distributing over networks. Compact Pro for several years in the early 1990's was a serious and popular competitor to StuffIt. However it has now been discontinued and is unsupported. For further reading about this unique and historic Macintosh program, see this Wikipedia entry.

For versions of Compact Pro 1.52 available in the English, French, German & Japanese languages: visit the official Compact Pro web site

Others DL actually submitted here: Compact Pro 1.51 (French), Compact Pro 1.33 (French), Compactor 1.21 (Extractor 1.12 and 1.21 included), Compact Pro Expand (a drag and drop utility from the same author).

Compactor was the previous name of Compact Pro...

Architecture: 68k PPC

Compact Pro works with all (Classic native) Macintosh models except the 128K and 512K.
Requires a Mac OS version 4.2 to 9.2.2.
It's a FAT binary program that runs fine on 68k & PPC Mac and the 3 main Macintosh emulators.
Also: StuffIt Expander can be used to extract Compact Pro (.cpt) archives, if the StuffIt Engine is present in the System Folder (Classic Mac OS).

I always preferred Compact Pro over Stuffit

I used to think that Compact Pro was an excellent Macintosh archival tool, up there with the likes of StuffIt.

But nowadays, my needs for an accurate archival tool has become more particular, and I find that Compact Pro is not up for that task at hand. Especially for folder date and times preservation. For example:

Not the result I had hoped to see.

While it is fine at preserving date and time stamps of the actual files, when it comes to extracting the folder hierarchy of an archive, it recreates all folders giving them date and time stamps from the time of extraction.

Compact Pro is safe enough to use if archiving individual files, disk images, etc, but it is not good enough should you wish to preserve the original time and modification dates of the original files including their enclosing folder structures.

When Compact Pro creates an archive from loose files in a hierarchical folder structure, the date and time info is handled correctly, including folders. If I extract a ".cpt" file using StuffIt instead to perform the extraction, all date and time stamps including those for folders are recreated correctly. So I know they are included in the archive. It's only Compact Pro's handling of the extraction that is poor.

Me too. StuffIt has also become more and more cumbersome with each new release.

After having thoroughly poked at every single version of StuffIt available here in the Garden just now, I wholeheartedly agree.

I always preferred Compact Pro over Stuffit, honestly.
