Unzipping (very) large files

I’m trying to flash an SD card with CloverLeaf and so far failing miserably (already trashed one memory card on Windows!) :(

Before I email Stefan directly, I wondered if anyone here could help.

The CLDistro Zip files are substantial in size, the smallest distro being a 16GB image compressed to 360 MB. Trying to open it on RISC OS gives “undentified header type found”, I’ve increased the maximum memory in SparkFS’s choices. Same error using InfoZip. I’m on a Raspberry Pi 3B V1.2.

Any help appreciated.

Don’t unzip it under RISC OS – RISC OS has a maximum file size limit of 4GB.

Ditto FAT32, so don’t unpack it into a USB stick or anything like that.

For a file that big you’ll need NTFS (Windows), ext3/ext4 (Linux), HFS+/APFS (fruity iStuff), etc etc.

Thanks both.
That may explain why I was having problems flashing the unpacked SD image on Windows.
I suspect I’m going to find it easier to ask Stefan for a ready-flashed SD card!

A Raspberry Pi running Linux and a USB card reader will do it easily.
