Dropbox is a sweet little application that syncs your files and folders across multiple computers and makes them all accessible from a web-based interface. In addition to that, the application also lets you restore deleted files in a jiffy.
So, what’s the tip?
There is a hidden folder inside your Dropbox folder that caches your deleted content. Deleted files from your Dropbox folder are stored locally in this folder. When you restore your deleted files, Dropbox quickly ‘recovers’ the documents from cache, instead of downloading it from Dropbox servers – saving you time and bandwidth.
