Today I found an "empty" directory with a size of 4MB.
It had no visible contents, so I tried
ls -lah. This showed me some hidden files (not very large). Searching for the reason why the directory was so large I found that the dot file (
.) had a size of 3.9MB.
What gets stored in that file? Isn't that just a kind of link to the same directory?
Here is the shell output (anonymized):
