|hg| Large Files Extension

Large files, such as image or zip files can cause a lot of bandwidth overhead during clone, push, and pull operations. To remove this inefficiency, |hg| has a large files extension which tracks their revisions by checksums. This means that the large files are only downloaded when they are needed as part of the current revision. This saves both disk space and bandwidth.

To find out more, see the |hg| Large Files Extensions Documentation.

To configure the large files extension, you need to set up your :file:`~/.hgrc` file.

1. Open your :file:`~/.hgrc` file.
2. Add largefiles = to the [extensions] section.
3. Configure the [largefiles] section with the patterns and file size you wish |hg| to handle as large. The minsize option is specified in megabytes.
4. Save your changes.
