I read about the byte vs cluster theory, but I don't think it can apply in my case;

Doesn't seem to have to do with "a bunch of small files";

The directory in question is an NTFS filesystem, with a symlink from an EXT4 filesystem.

I'm not sure why byte vs cluster doesn't apply here.

The total size of the files represents the size of the actual files in bytes. When files are stored on disk they often take up more space as they will use up complete clusters, even if the file is much smaller.

Based on the fact that this is an SVN directory, which typically has a large number of very small files, it would explain why the size on disk is much larger. I file with only 10 bytes in it could take 2KB on disk depending on your cluster size.

Cluster sizes vary depending on the file system and the size of the hard drive.
