There are some files and folders that have a red X on them. What are those? What does that red X represent?

enter image description here

  • @Zanna I mentioned the root folder as an example...My question is general about files and folders with the same icon.

  • I think you are using a modified icon theme; the X is not red, it's grey (at least in 16.04).

The red x means that you have no access (Permissions) to these files and folders as the user currently running nautilus (the file manager nowadays called stupidly Files).
