File & Folder Sizes

This may be a bit of a review for some of you. On occasion you may need to know the size of a file or folder. This is not difficult to determine in the macOS, but there are a few settings that may be helpful.

 

The Finder

When it comes to the Finder, I am a Column View man. I have been for many years. However, there are some reasons for using List View. Determining file and folder sizes is one of those reasons. If you want to do a one-off to find the size of a file you can use the Get Info command in the File Menu or Command ⌘ + Letter “i” keyboard command. The Finder will show you a window like this:

FilesFoldersSizes

You can see the file size, Permissions on the file and a few other attributes. However, if you want to get an overview of a bunch of files and folders, then the best way to do that is to switch your Finder to List View:

FilesFoldersListView

Click on the little icon to the left of Column View and you are in List View:

FileFolderSizesList

As you can see, List View shows you the File Size. If you wish to see Folder Size you have to open the Finder “Show View Options” window:

FinderShowViewOptions

Once you are in that window look for “Calculate all sizes” and check it:

FileFolderCalculateAllSizes

When “Calculate all sizes” is checked, you can see the Folder Sizes as well:

FileFoldersFolderSizes

When I am finished using this method to find File & Folder Sizes I always revert to Column View. That is just the way I roll.

Conclusion

So, this is no big deal. If you need to determine the size of one file, use Get Info. If you need to determine the size of multiple files and/or folders, go into List View.
