改变git结构

Question

Currently I have the following folder structure:

root
  .git (folder)
  Folder A
     SubFolderA
     ...
  Folder B
  ...

And I want the following structure:

root
  Folder A
    .git (folder)
     SubFolderA
     ...
  Folder B
  ...

How can I do this without destroy my current repo?

Thanks in advance.

Answer 1

If you really want that, then go ahead and move it:

$ mv .git FolderA/
$ cd FolderA/
$ git add .

But notice how all files in FolderB will now be out of source control:

$ git commit -m "Remove all but FolderA from source control"
[master d044479] Remove all but FolderA from source control
 10 files changed, 5 deletions(-)
 rename FolderA/FileInA1 => FileInA1 (100%)
 rename FolderA/FileInA2 => FileInA2 (100%)
 rename FolderA/FileInA3 => FileInA3 (100%)
 rename FolderA/FileInA4 => FileInA4 (100%)
 rename FolderA/FileInA5 => FileInA5 (100%)
 delete mode 100644 FolderB/FileInB1
 delete mode 100644 FolderB/FileInB2
 delete mode 100644 FolderB/FileInB3
 delete mode 100644 FolderB/FileInB4
 delete mode 100644 FolderB/FileInB5

You don't have to worry about these other files if you want to read them later, their history is not lost.

For example, if you decide to roll back this commit you can always do that:

$ git reset --hard @^

Notice how this will recreate a second copy of FolderB under FolderA/FolderB :

..
