I have a lot of .img files here, probably between 100M-400M. Since these files were created long ago, probably around 2002. Because these files attribute contains the words 'Aladdin Systems, Inc',and there are also lots files with .sit extension created at the same time,I suspect these files are some kind of image file, but I can't find software that can open them. I have tried software such as StuffIt Expander.

Hello and welcome.

Because they state NDIF and Mac OS HFS in your screenshot, they look to me like old Mac OS 9 disk image files. NDIF stands for New Disk Image Format and were probably made with the Disk Copy 4.2 application. Because of the age, and that mcOS moved to Universal Disk Image Format which produces .dmg files, it may be tough to find a way to open them in more recent versions of OS X/macOS.

Do you happen to have access to an old Mac running OS 9, or an earlier version of OS X that supports OS 9 Classic mode - 10.4 or earlier with a PowerPC processor? Those would be able to open the .img files.

The .sit files are indeed Aladdin Stuffit archives. Not sure if Stuffit Expander 16 will open the legacy .sit files.

I will look around and see of there are other solutions.

Thank you very much for your reply.
Yes, I have tried mac os 9. It's hard to find a computer running os 9 now, so I used SheepShaver to run mac os9, but I still can't open these files.

I downloaded some very old disk utility software and would like to try to see if I can open these .img files. Then I found out that there are also files in .img format in these files, which can't be opened either.
