tortoise git backup empty folders

[Sand Glass]

I use tortoise git in windows, how to backup a empty folder automally?

I know git only backup files, so it will ignore empty folders.

In linux you can run this command 'find . -type d -empty -exec touch {}/.my_git_keep \;' before you commit a folder. Thus can create a .my_git_keep file in each empty folder.

But in windows bat file, how can I write a script to get to the upper result?

Tortoise git is based on UI, when you backup a project, usually use the follow steps:

'into your project folder' -> 'git create a repository here' -> 'add' -> 'commit'.

So, can I create .my_git_keep file in each empty folder automatically in 'add' step?
