Hi All, I'm looking for a very simple utility. I'm certain someone somewhere has created one but can't seem to locate anything through Google. Basically I need a utility (preferably web/browser based) that will display a GUI of the customers file structure (much like explorer) and allow the user to click on empty boxes next to the files/folders to select them. Once the user selected files and folder are selected, I'd like the utility to add or sum the total storage size for all files/folders selected and produce the total size. Basically the utility will be used for customers who want to do an online backup but don't know how much their storage will be (specific files/folders selected for backup vs. entire drive). If there isn't a utility available can anyone suggest the best method/language to write on in or can you provide any links or tutorials that might help me create it if necessary? Any help is very much appreciated. Thanks in advance.
