Add folder size on disk as a icon info

[KingSupernova31]

In Nemo, I can choose to have it display information beneath an icon, like its date created, date modified, etc. Oddly, folder size is not one of the options. I can display file size, or the number of items in a folder, but not its actual size. To see that I have to right click and go into properties.

This is not an objection to your proposal, merely a thought to focus more thought: Do you want the folder size to include only the sizes of the files in the folder or do you want it to include the sizes of all sub-folders and sub-sub-folders recursively? Also, are you more interested in the size of the blocks occupied on disk, or only the actual bite sizes of the files? Windows hides a lot of these complications from the user, but Linux provides an embarrassment of riches in this area.

Should certainly be recursive; the primary use-case is stuff like "how much space do I need to put this folder on a different drive", or "how much space will I free up by deleting this", or similar.

For exactly how that's counted, I think it probably doesn't matter too much? The average user won't care about the difference, and someone who does care probably knows how to use command-line tools to find out. If it does matter, then there could be an option in the preferences to let the user pick.

Ideally counted exactly as du does.

Imo, you're quicker to create a Nemo action.

As Secret-chest said, use a bash script like du -M $1 (M=mb, G=Gb, etc).

Connect that script to a Nemo script and with zenity as dialog box you'll be able to display folder sizes.

Well, that's usefully clear, thank you. As you mentioned, there are people more likely to be using the command line for this sort of thing, but there's no reason it can't also be in the GUI.

I also like @Jopp-gh 's suggestion of creating a Nemo action. It should be fun to try and not too challenging. I haven't experimented with Nemo actions, but I suspect there's a way of putting an action on the context-sensitive menu, yes?
