You can do it easily in Opus as well. There are several threads with different methods on the forum.
If you have trouble following instructions on how to do something, please link to them so which know which thread you're looking at, and also tell us which part you're having trouble understanding. We can provide mode detail if we know where you're stuck.
Folder sizes are only calculated when you ask for them, by default. (Since it can involve a lot of disk access.) Push Ctrl-K (or Ctrl-L in older configs) or use Edit > Calculate Folder Sizes.
You can also make calculation automatic (see the FAQs for details) for some or all folders, but I wouldn't advise doing that outside of things like a downloads folder where you know there won't be a lot of sub-folders to dig through every time the sizes are calculated.
Thanks, I already use RED, but I thought this would be perfect suitable for integration in DO. But you have done already. Could you tell me how to place a button to RED on the toolbar? (I am new to DO)
I would prefer the easiest method. Since I am new to DO and need to become familiair with it. Easiest approach for me would be to implement a function under Tools (which is already on the menubar), but I guess it isn't that simple
Since I am new to DO I cant write any script or filters etc.
If you use Ctrl-K in the results to calculate the sizes (which should be very quick), you may see some folders are "empty" (literally nothing is inside them) and others are "0 bytes" (may have 0 byte files or other folders with nothing or 0 byte files below them). You may only want to delete the ones which are 0 bytes.
Empty folders don't cause any harm, though, so I don't know why so many people obsess over finding and deleting them all, or what is creating them for that matter.
More automated solutions are also possible, but require setting up a toolbar button. Creating toolbar buttons is easy, though:
For me, the need to delete empty folders usually relates to the project that I'm working on and the need to reduce the number of folders that need to be processed. Once I've processed the files in a folder, I want to get rid of that folder so that I'm not continuously clicking into that folder only to find it's empty. But I often process dozens (or more) of folders at a time, thus leaving behind a bunch of empties.
Hi everyone! The method im using is with label filters. I have a button, if i toggle it, it will enable a created label filter which colores the folder name or background of empty folders. This is not a solution where you would want to see ONLY empty folders.
Settings - Preferences - Fav and Recent - Labels
Here you create a label with coloring (i call it EMPTYLABEL)
Settings - Preferences - Fav and Recent - Label Assignments
Here you create a label filter: (i call it EMPTYFOLDER)
Type match folders
Size match is equal to zero
Assign the already created EMPTYLABEL
Toolbar rightclick - Customize - New Button
Set ENABLELABELFILTER EMPTYFOLDER,toggle
So every time i need to highlight empty folders i click on this button and DOpus colors the background of the folders.
