automatic calculate folder size

[alangeer]

Is there a way to have all folder/file sizes automatically calculated? Or can I perhaps create a shortcut key or something to calcualte the currently highlighted file/folder?

Thanks!

It would be cool if we could have ⌥⌘S for calculating size in all folders.
Moreover any operation in the pane kills all folder sizes, even the operation doesn't affect the calculated folders (why). This is serious problem, coz I need to recalculate everything all over again.

This is a pretty tricky issue.

First of all, autocalculating folder size would consume much system resource. It could be done for the local filesystem (we did plan on that at one time), but would put too much load on a remotely connected server, and simply seems too much radical.

Retaining the sizes of folders you have already calculated brings up a question: How should ForkLift know that you changed the contents of a folder on which you have calculated the size previously?
If you change the folder with an other application (say Finder) FL will have no way to know this, and the stored folder size will be wrong.
Now Leopard does have a series of new technologies that would possibly enable this, and we may take a look at this in the future, but not immediately.

Okay, but I just want to keep the calculated size for folders that weren't modified inside of FL until I do refresh (not forever). It is not the problem about Finder or any other application that does the modification in the background, but the simple thing -> example:

I want to clean-up some folder, I do Cmd+A and Shift+Cmd+S to calculate size of all subdirs [we miss a keyboard shortcut for doing this for all forders :(]. Then I sort per size.
Anytime I touch any file or delete one folder in the pane I need to recalculate all other folders again. This is very very annoying!
Total Commander on Windoze which is good sample of mature file manager does it well (don't touch size of folders that weren't modified), I don't see why FL shouldn't behave the same too.

Just for the record:
Automatic folder size calculation has been added in 1.6 beta. It also keeps track of changes in the local file system and recalculates when needed - thanks for FSEvents :)
