Utility and Performance
When you take a look at the features of Google Desktop, you'll find almost everything useful right from the Quick Search Box. Smart Indexing is the way you get the most relevant search results, down to the provision to recover files with cached copies and regular updates.
Soon after the installation is over, Google Desktop starts indexing everything from the local files on your computer down to the web history and emails. When your PC is left idle for thirty seconds, the app indexes everything, ensuring that the process of indexing doesn’t slow down your PC. However, the process continues for several hours, though again without affecting the performance of your PC.
Don’t Miss a Thing!
The application keeps updating the index every time you modify a file, receive a new mail, or delete something.
Recovering Accidentally Deleted Files With Cached Copies
Furthermore, it also keeps cached version of deleted files, and hence you may use these cached version to retrieve info from accidentally deleted files.
Customizing Sidebar and Plug-ins
To keep your Google Gadgets organized in your sidebar, you also have a control panel, which allows you to drag-and-drop your favorite gadgets, and hide/show the sidebar along with other application screens. So, the choice is totally yours; customize things the way you like!
