[How to do instruction] reduce img file size of backup

[Man in a van]

I've been trying to trim the size of a backed up img file (from an 8 gig micro sd card).  After win32diskimager has done its thing, i'm still stuck with an 8 gig image.

Tried : installing linux on a virtual machine using pishrink only to have a questionably sized, non bootable img.

Found a much easy way (and tested it).
1.  Install a hex editor (i used hex editor neo).
2.  Remove the zeros from the end of the file to the end of the code.  I left a few 0's behind just incase.
3.  Save file. 

That's it.

Would you have time to pop a couple of screen shots up please.

win32diskimager v1.0 has a procedure to reduce the size of the file. I have found that sometimes it works and at other times it doesn't

These days I use

to make a copy onto a usb stick and run pishrink on a raspberyypi3B or 3B+. Works very well.
