Created attachment 104107 [details] screenshot Hello! Baloo does not shows the summary file size when the user searched for files and the results have been returned - at the bottom right corner it states "Unknown file size" instead something like "4 files, <sum-of-their-sizes> MB" (See the screenshot).
If you want to see the sizes of the individual files, you need to add the Size column. Right-click on a column header("Name" in your screenshot) > check "Size". However I do see the issue: the typical volume size widget in the bottom-right corner displays "Unknown size" instead of something useful. We should probably just hide it in the search view, since search results could span multiple volumes.
