Attached larger files. *.sav file = 4.6 MB in disk *.zsav file = 234.6 kb in disk
The compression ratio is not always proportional, but here a sample that can do a lot (I'm very surprised). I have not been able to make objective evidence, however, I have been working with files up to 1 GB of disk size (zsav), and really not noticeable performance down to use the same file (sav format almost 2 GB).
