Version control: from zip to git

Question

I have three zipped folders named [1,2,3] each contains the same project 1 being the earliest and 3 being the most current. I am looking for a way to merge all of these into 3 git commits and the 3 most commit be the folders contents.

I suppose I can do the following:

1. Unzip 1.
2. Take the contents from 1 place it into a new folder.
3. git init
4. git add -A
5. git commit -m "first commit
6. Unzip 2
7. replace the contents from the new folder with contents from 2
8. git add -A
9. git commit -m "second commit
10. Unzip 2
11. replace the contents from the new folder with contents from 3
12. git add -A
13. git commit -m "third commit

Could anyone tell me if this is the best way to do this?

Answer 1

Unzip your three zip file in three different directories.

Initialize a git repo in a fourth directory.

Then take advantage of the --work-tree option, which allows you to execute a git command from a git repo, but with a content located outside of said git repo:

cd /your/git/repo
git add --work-tree=/path/to/zip1 -A .
git commit -m "Add v1"
git add --work-tree=/path/to/zip2 -A .
git commit -m "Add v1"
git add --work-tree=/path/to/zip3 -A .
git commit -m "Add v3"

In other words, you can add different contents without moving from your git directory!

Answer 2

Here's how I would approach this

Get Version 1 commited

mkdir MyProj
cd MyProj
git init
# unzip version1 into MyProj
git add -A
git commit -m "Version 1"

Get Version 2 committed

# delete everything but the .git directory in MyProject
# unzip version2 into MyProj
git add -A 
git commit -m "Version 2"

Get Version 3 committed

Repeat the above for version3 of the zip file.
