That does not mean I am skilled at using 'ditto'. I know ditto exists, and I can read the man page to see it says it support hardlinks and hfs compression. It also says it can provide HFS compression.Īnd, no I do not know what command you should use. Some of that is because the standard Unix file system API's does not make that information available to utilities such as 'cp'. NOTE: This is less likely to happen, as most consumer files do not take advantage of sparse files.īasically the 'cp' command is rather simplistic with regards to how files are actually stored in a file system. the 'cp' command does not know this, and allocates storage for those holes. So there may be files with islands of data with nothing allocated in-between. MacOS has the ability to compress stored files, but the 'cp' command is not going to trigger that compression, so a file may expand to use more space.ĭepending on which version of macOS, there may be 'sparse' files, where large ranges of zeros in the file, do not even have allocated storage. The 'cp' command does not know, and does not care if you have hardlinks.

There can be other hardlinks situations on macOS.

If you have an iPhotos and a Photos library, there are hardlinks (multiple directory entries that point to the same storage).
