To find details about a files size, you can right click and select "Get Info":

Get Info Window

When I select a large number of files, and want to get information about all if them together as a single selection, such as the combined total size, I get the same window for every individual selection, and not a single view for the selection as a whole.

How can I get total file sizes for file/folder selections?

  • YEAhhh, Good to see that not only me is getting annoyed by such a stupid design.

Instead of +I use ++I to see the info:

Cmd+Ctrl+I does something similar, but gives you a static Summary Info window which doesn't update as your selection changes, and you can open multiple windows for different selections, which is handy for comparing groups of synced folders for example.

  • Yup, that's it!!

  • @daviesgeek I actually didn't know this before. But I always try the option key when looking for new features.

  • Select the files
  • right click
  • hold alt (notice the menu options change)
  • select 'Show Inspector'

    your solution stops halfway: select 'Show Inspector' from the menu then

  • @schellmax Then a dialog window showing information of multiple files is being opened, i.e. exactly what OP is asking, there're no other steps. What's the other half of the way supposed to be? Jan 28, 2021 at 20:51
  • @DavidFerenczyRogožan trying to remember what i meant here 3 years ago :) - but it seems i was referring to an older version of the answer (see edit history)
