I'm wrote the Diff All Files Visual Studio extension, which pulls files down from TFS source control in order to bulk compare your changes more quickly.I'm now adding Git functionality to it, but cannot seem to locate the class that I should use in order to pull files from the Git repository.

You cannot. With git, you clone the entire repository, and the full history of the repository.
There are some workaround solutions to be able to get a single file out of a git archive, listed on a Stack Exchange answer for the same question, but you will still have to download the entire repository to get that single file or directory you want.

dobey's answer is no longer the case since git v1.7. You can now checkout certain folders from a repository. The full instructions are found here.
This tells git which directories you want to checkout. Then you can pull just those directories

First, do:
Then:
...And lastly:
It's that easy. Git will rewrite the repo so that only the desired sub-dir is included. This works even if the sub-dir is several layers deep. Just name the destination directory the name of the sub-dir. Then in the 'git filter-branch' command put the relative path to the sub-dir. Oh, the
--depth 1
tells git
to only download the top of the head (essentially removing the history).CelticParserCelticParser
git clone --filter
from Git 2.19This option will actually skip fetching most unneeded objects from the server:
The server should be configured with:
There is no server support as of v2.19.0, but it can already be locally tested.
TODO:
--filter=blob:none
skips all blobs, but still fetches all tree objects. But on a normal repo, this should be tiny compared to the files themselves, so this is already good enough. Asked at: https://www.spinics.net/lists/git/msg342006.html Devs replied a --filter=tree:0
is in the works to do that.Remember that
--depth 1
already implies --single-branch

Test it out
GitHub upstream.
Output in Git v2.19.0:
Conclusions: all blobs except
d1/a
are missing. E.g. f70a17f51b7b30fec48a32e4f19ac15e261fd1a4
, which is d1/b
, is not there after checking out d1/
.Note that
root/root
and mybranch/mybranch
are also missing, but --depth 1
hides that from the list of missing files. If you remove --depth 1
, then they show on the list of missing files.Git Download File From Repository Windows 10
