I have a 5GB folder with my research from last year. To save space, I compressed the folder, and all its contents. The compressed file
*.tar.xz, is 761MB, which seems really tiny. That made me wonder:
How can I verify the contents of the compressed file against the uncompressed directory? Is 761MB really correct? how can I know? Is there an easy way to figure that out? Or, is there something which will give me more details about the compression? ... As in something that might say: Your 5GB folder will 761MB using this compression type....
That information could be really handy to know. Right now, I am using options available for compression via the file manager, caja. I am using mate, Ubuntu 14.04.
command line options are fine too.
