It is considered good practice to use a prefix when creating git archives, so that extraction will place all files inside a directory. To create an archive of HEAD with a directory prefix: git archive --output=archive-HEAD.zip --prefix=src-directory-name HEAD When extracted all the files will be...

It is also possible to create archives of other items than HEAD, such as branches, commits, tags, and directories. To create an archive of a local branch dev: git archive --output=archive-dev.zip --prefix=src-directory-name dev To create an archive of a remote branch origin/dev: git archive --...
