Mac: Desktop clutter builds up when we don't bother to clean up and organise files we've downloaded or created. While there are ways to automate this process, it doesn't provide full control over where your stuff goes. Factura is a drag-and-drop app that makes file archiving on your Mac easy.
To use Factura, you drop any files you want to archive, give it a category name and hit return. It will automatically create a folder in the archive directory of your choice and move (or copy) the file you want to archive. It will also prepend the date to the file name so everything is sorted in the order it was archived. This will make your archives easier to browse. It still takes a little effort on your part, but cleaning up should be easier.
