A simple method is to put all your files in a tar archive on your Win10 machine.
Winzip, WinRAR, 7-Zip etc...  are some programs that can do that : https://dailydoseoftech.com/how-to-open-...on-windows
Use a short (max 8 characters) name for your tar file and  put it in your ISO file.
Your can then untar it in the emulated IRIX from the mounted ISO file and install your software.

cool, that'll be great for getting Blender installed.

But I'm running LinuxMint 19.3 and the newest Mame I can get for it is something like 1.93 (I'd have to check again, I forgot). I can't get .223 installed without upgrading to mint 20 (I need libc6?), and it doesn't appear 1.93 would run the emulation at all. To upgrade to 20, I'd have to downgrade a lot of packages (according to the directions I can find), and I don't know if I could upgrade them all again. I may eventually give it a try if I can't find another way around it.
