I have 4 files that I want to include them in a .zip file.

As you can see in total their size is 16K.



After



I am creating the zip using the command bellow:



zip -r myfiles.zip *


The file was created successfully but now its size is 20M, as you can see bellow!

ps: Same thing (same size) happened when I try to create a .tar using tar cvf myfiles.tar *.

    A individual directory always shows the 4k size when viewed with ls - what you want to use to check before is du - ie, du -sh *

    FYI, 4K * 4 = 16K, not 32K. Also, in this case this is due to a misunderstanding of the size that ls reports for directories (that each directory was the exactly the same size should have been a hint that maybe ls isn't reporting what you think), but in general you should not necessarily be surprised if compression sometimes produces a larger file. Compression can't compress everything; otherwise you could repeatedly run zip on a .zip file to get increasingly smaller files.

    @Themelis I stand corrected. They are "files", they are just not "regular files", which is important here.

An individual directory always shows its own size when viewed with ls - no matter the size of its contents. What you really want to use to check before is du - ie, du -sh *.



A good explanation of what the size of a directory means is on this Q&A - What does size of a directory mean in output of 'ls -l' command?

    The size show by ls for a directory is not false, it is the size of the directory. However the size of a directory is related to the number of entries in it (possibly the largest number it every had), not the size of those entries.

    @Themelis - or more. It is meta-data about the directory and contents, so if your directory has lots of files or subdirectories, etc it will get larger. Key is to remember the size shown for the directory is about the meta data, not the sum of the sizes of the contents of the directory.
