Review for Extra Folder Columns by Almidec
Rated 4 out of 5 stars
It works as it should EXCEPT that the Size column is not in the same units. It should be all MB or all KB (without the suffix) so that we can see at a glance the comparative sizes. 3MB is much more than 895KB but hard to see quickly. One common question is: where are my big folders. 3000MB and 895MB is easy to compare and see.
