One of the Windows Explorer’s many small and niggling annoyances is the way it displays the size of a file, but not the size of a folder, which is handy to know if you are looking for the programs and files that are gobbling up your hard disc space.
This little utility found by Propellerhead, called appropriately enough Foldersize, sets things straight, in Windows Explorer’s Details view just right-click on the column title bar, select Folder Size from the drop-down menu and the new column will appear, with the amount of disc space both folders and files occupy clearly displayed. This makes the standard File Size column redundant so if you want to get rid of it right-click on the title bar again and uncheck ‘Size’.
If you want to reposition the File Size column simply drag it to the spot on the bar where you want it to be. Don’t forget there are hundreds more great tips and links to free software on the PCTopTips website
