The media part of a project tends to have a different lifecycle than the text or code part of a project. In practice, many multimedia projects don't need or want to track the media's history. So Git just takes all the data and makes a new copy of it, even if only one pixel changes from one photo to the next. Raster images and music files make as much sense to Git as they would to you if you looked at the binary data contained in a. The reason static content causes Git to grow in size is that formats based on text allow Git to pull out just the parts that have changed. The time to perform pulls and pushes goes from being how long it takes to take a sip of coffee to how long it takes to wonder if your computer got kicked off the network. When a Git repository becomes very large, the major cost is usually speed. The cost of committing files that aren't text-based is minimal at first, but the longer a project stays active, the more changes people make to static content, and the more those fractions start to add up. You can perform tests to get a better average, but this simple demonstration is consistent with my experience. You can see the problem here: Removing a large file after it's been committed increases a repository's size roughly eight times its original, barren state (from 108K to 828K). So, let's try removing the file: $ git rm dandelion.tif Nothing unusual so far adding a 1.8MB photo to a directory results in a directory 1.8MB in size. two photosġ file changed, 0 insertions(+), 0 deletions(-) Here's an example of copying a photo file using Git: $ du -hs It seems to be common knowledge that Git doesn't work well with non-text files, but it never hurts to challenge assumptions.
The problem with managing multimedia files with Git

In this final article, we'll look at software that brings the advantages of Git to managing multimedia files. In this series leading up to Git's 14th anniversary, we've shared six little-known ways to use Git. However, the advantages of an asynchronous workflow are appealing, especially in the ever-growing number of industries that combine serious computing with seriously artistic ventures, including web design, visual effects, video games, publishing, currency design (yes, that's a real industry), education… the list goes on and on. Git is very specifically designed for source code version control, so it's rarely embraced by projects and industries that don't primarily work in plaintext.
