Display folder sizes in file manager

In nautilus (or nemo) file manager, the "Size" column shows the filesize for files and the number of items contained in a folder for subdirectories:

Number of items is not that important for me, it would be more useful if I could make this column show the total size contained under the directory. I had an extension on windows called foldersize which shows what I mean:

I think it involved a service which ran in the background monitoring filesystem modifications in order to make sure the column was kept up to date.

I am interested to know if there is any similar extension to nautilus, I would also be open to switching to another file manager to get this functionality. I am aware of the Disk Usage Analyser in Ubuntu, but what I'm looking for is a solution with file manager integration.

Solution 1:

Not sure if this will help as it's not exactly what you're looking for, but you can display the file size under the icon:

1. Open the file explorer
2. Go to places
3. Select preferences
4. Select display tab

However, this is probably a more direct answer to your question: Show current folder size in Nautilus
