Get the Size of Multiple Files – Mac Kung Fu, 2nd Edition

Tip 188Get the Size of Multiple Files

You probably already know about the File Info window, which you can open by selecting a file and hitting Command+I. This shows details about the file, such as its size, where it was downloaded from (if applicable), and so on.

Highlighting several files at once and hitting Command+I doesn’t do what you might expect. Instead of showing a combined info window, it opens individual Info dialog boxes for every single file you’ve selected.

The solution is to highlight the files in question and hit Option+Command+I instead. This will open the less-well-known Multiple Item Info dialog, showing the combined size of the files (useful if you’re planning to burn them to CD or DVD, for example).

The Multiple Item Info dialog is dynamic; that is, you can Command+click additional files while it’s open, and it will update to reflect the new total size.
