How to decompress MPW 3.x images

I have tried to install MPW 3.2 on my Mac SE/30, but cannot decompress the disk images (example: MPW2.image) even though I have Stuffit Deluxe Ver 4.o on my Mac SE/30. I have downloaded the MPW disk images from Macintosh Garden and Macintosh Repository sites, but all the MPW 3.x archives include disk images with .sea files that do not open with Stuffit Deluxe 4.0. I get an error message that states that these .sea files are segmented archives that cannot be opened. I am using FloppyEmu as an external drive on my Mac SE/30 to mount/open the MPWx.image disk file. The MPWx.image file appear as MPWx disks on my Mac SE/30 System 7.1 desktop. I double-click on the MPWx disk and see the .sea file as the only file on the disk. Is there a web-site that has the MPW 3.x disk images that are not compressed .sea files?

If you are talking about MPW

If you are talking about MPW 3.2.3 downloaded from here: https://www.macintoshrepository.org/download.php?id=2186

 

Here is the content of MPW 3.2.3 DISK IMAGES: Package iconMPW 3.2.3 DISK IMAGES.zip

 

You can use https://extract.me/ to extract the individual .hqx files into .image files that you can simply mount or drop into Mini vMac. There are no .sea files:

Please see MPW2 disk image

Thanks for the reply. I am able to extract/decompress the large .bin or .sit files that contain the disk images. It is the individual disk image files that have the .sea archive file (please try the MPW 3.2.3 MPW2.image disk image in Mini vMac). I get a MPW.sea.#2 file when I open the MPW2 disk in Mini vMac. When I mount/open the MPW 3.2 - C SARez.image and open the disk image in Mini vMac, then I see the same two files C 3.2 and SARez (no problematic .sea file with this disk image) that you show in your Mini vMac screenshot. I am trying to decompress the MPW.sea.#2 file. I've tried Stuffit Deluxe 4.0 on my Mac SE/30, but Stuffit gives an error that it cannot open the MPW.sea.#2 archive because it is segmented archive.

Looks like you need to

Looks like you need to install Compact Pro on your Mac. Here is what happens when I drop MPW2.image:

The .sea name indicates a

The .sea name indicates a Self-Extracting Archive—which should be a runnable application. Classic MacOS does not assign any meaning to file extensions so this may simply be a red herring: using File Buddy or BunchTyper (or ResEdit!) you can check to see what the type and creator of the files actually is. The type and creator are the only bits of information used by MacOS to decide how to open a file when you click it.

A real self-extracting archive will have type APPL.

You can, of course, also open self-extracting archives in the program that created them, whether that is Compact Pro or StuffIt.

StuffIt Deluxe or Lite can open CompactPro archives by way of a translator.

 

The file "MPW (Archive 2)" on the volume "MPW Disk 2" has type PACT and creator CPCT. This is not a self-extracting archive, it is a Compact Pro archive.

Aaaaand by reading the "Read Me - MPW Installation" file on the volume "MPW Disk 1" we learn:

By following these instructions (although you don't need to eject and insert, MinivMac can load all 5 disk images at once) I was able to successfully install MPW 3.3 (although it requires at least System 7.0 to run it). It does not require any other archive tool.

Just completed MPW 3.3 install

Thanks for all the information. Followed the Disk 1 installation instructions and the installation went smoothly. Now, on to installing Language Systems Fortran compiler.
