What are HFS files and how to open them

Are you having problems opening a HFS file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a HFS file?

A .HFS file is a Hierarchical File System disk image file.

Files with file extension HFS contain files and folders in Hierarchical File System format, a file system used by Macintosh floppy disks, disk drives, and CD/DVDs.

The first version is also referred to as Mac OS Standard, while the newer version, HFS+, is referred to as Mac OS Extended.

If you need to access the files inside an HFS file, you either need to mount it as a drive on a Macintosh computer or extract the data with a data extraction tool. If you extract the data, you likely cannot run the programs contained in the HFS file, but you can inspect the data files.
