How to restore a whole directory from history of git repository?

try adding '--' between revisions and paths:

git checkout 348ce0aa02d3738e55ac9085080028b548e3d8d3 -- path/to/the/folder/ 

And if you want to recover a directory from the previous commit, you can replace the commit hash by HEAD~1, for example:

git checkout HEAD~1 -- path/to/the/folder/ 

There are two easy ways to do this:

If the commit that included the errors only included the errors, use git revert to invert the effects of it.

If not, the easy path is this:

1. git checkout 348…
2. cp -a path/to/the/folder ../tmp-restore-folder
3. git checkout HEAD # or whatever
4. rm -rf path/to/the/folder
5. mv ../tmp-restore-folder path/to/the/folder
6. git add path/to/the/folder
7. git commit -m "revert …"

For modern git (-s or --source):

git restore -s commit-sha-that-contains-dir relative/path/to/folder

man reference:

-s <tree>, --source=<tree>
   Restore the working tree files with the content from the given tree. It is common to specify
   the source tree by naming a commit, branch or tag associated with it.

   If not specified, the contents are restored from HEAD if --staged is given, otherwise from the index.

   As a special case, you may use "A...B" as a shortcut for the merge base of A and B if there
   is exactly one merge base. You can leave out at most one of A and B, in which case it
   defaults to HEAD.

git checkout -- path/to/folder/
