Git: how to migrate all local repos to another machine?

I have code files from dozens of git repos in various subfolders under c:\code folder - 16Gb.

I want to migrate this folder to another computer. It's currently taking > 1 day to copy the entire folder to a USB drive, because it is around 650,000 small files.

Is there some script I can run to cleanup all of the repos in my c:\code folder?

Edit: all of the repos have a remote. I don't care about copying all branches. I only care about keeping the directory structure of the repos, i.e.

c:\code\github\NLog
c:\code\github\Swashbuckle.AspNetCore
c:\code\myclient\DevOpsProject1\solution1
c:\code\myclient\DevOpsProject1\solution2
c:\code\myclient\DevOpsProject2\solutionx
etc

What I was originally looking for:

find . -name .git -type d -execdir git clean -dxf \;

This cleaned up my 16Gb of files across all repositories down to 800Mb. And then @VonC's answer (N.B remove v option from the below to be quieter)

tar cpvf code.tar code

and then on the destination machine:

tar xpvf code.tar

Whenever I would use git in the copied folders, I then kept getting errors:

fatal: detected dubious ownership in repository

So to fix that I had to "Take ownership" of the folder. I'm on Windows, which meant Properties of the code folder -> Security -> Advanced -> Owner -> Change. Even though "Local administrators" owned the folder, and I am a member of that group, I had to make myself the owner.

An additional hurdle was because I'm on a corporate machine I couldn't see the Security tab. Here's the fix for that.

You can use git bundle to bundle each of the repositories full history into one file (per repository)

And you can zip the dozen of bundle into a giant tar file.

Result: only one (big) file to copy, and to untar.

You can then clone back your repositories from their respective bundle (cloning them from their bundle file).

I don't care about copying all branches. I only care about keeping the directory structure of the repos

The, an alternative approach is to simply tar cpvf code.tar code under C:\.
Copy the giant tar file to the target machine, and tar xpvf code.tar: the directory structure will be preserved.

A bit as in here:

find . -name "*.git" -type d -exec tar -czf {}.tar.z {} \; -exec rm {} \;

(Be careful with the -exec rm part: test it out first).

You clone only lasted commit from your remote repository like

git clone --depth 1 https://url-of-your-repo
