Win32DiskImager working with compressed files

Question

Win32DiskImager is a cool tool on Windows except:

we have to manually extract the ZIP file and then flash it, and then delete the ZIP
it doesn't seem to work in command-line

Is there a way to make it work with compressed files? like:

win32diskimager image.img.zip e:\

@CoderMike Looks cool, this seems to be a solution (feel free to post as answer)! — Basj, Jul 27, 2018 at 16:08

I use Etcher - i've found it more reliable than Win32DiskImager and it will write an image direct from a compressed image.

What is the correct way to compress an image for Etcher? (Compressing to a zip file with Windows 10 causes Etcher to complain and fail. Um, or I did something wrong.)

@BobBrown Take an .iso or .img, compress it with ZIP (it will be a zipped IMG) e.g. myimage.img.zip. Then Etcher seems to accept it. Pros: you don't need to uncompress 400 MB zipped images to 3 GB file before flashing.

@Basj Thank you. Based on your comment, I've used gzip to reduce a 15 GB image to 3 GB and then flash to SD card. (I'm now going to have to look into making smaller images because even the compressed file takes 40 minutes to flash.)
