: Photoshop: "Save for Web -> Done -> Save" results in different file size than "Save for Web -> Save..." I have a large number of PNG images that are organized in some specific directories

I have a large number of PNG images that are organized in some specific directories and subdirectories, like this:


0


0


0.png


1


0


0.png
1.png

1


0.png
1.png




, etc.

The problem is, their filesize is too big. In order to reduce it, I've tried to create an Action for optimizing and saving the whole batch via Save for Web option.

First, I open the image which initial filesize is 256KB. Then I adjust the Save for Web window parameters, and the filesize it is indicating is 27.55KB.

From here, I've tried two different approaches:



1) Clicking Save... from the "Save for Web" window.

The final filesize here is 27.55KB, as promised, but the problem here is that saves the image to the directory I manually choose, there is no way to just overwrite the image. So when creating a batch action it outputs the images to the same directory and thus wrecks the whole folder organization.



2) Clicking Done in the "Save for Web" window, so it closes with the settings supposedly applied to the image.

Then I save the image the normal way (Ctrl +S), so it just overwrites the original image, and thus the file organization is kept the same, which is good.

The problem here is that the final filesize is 173KB instead of the "promised" 27.55KB. So I suppose that it's not the same clicking "Done" and then saving than directly saving from the "Save for Web" window.



How could I solve this?
I am using Photoshop CS6
