Wings for your Windows Explorer!
Clover is an extension of the Windows Explorer, to add multi-tab functionality similar to Google Chrome browser. After Clover is installed, you will be able to open multiple folders in tabs within the same window, and you can also be able to add folder bookmarks.
Note: If you're starting Clover with a bunch of previously opened tabs, so don't be hurry for some first seconds 'cause it can freeze. Also be aware to delete some files if you use Ctrl-D hothey for bookmarking a folder 'coz the same hotkey you can set for deleting without prompt if you unchecked "Show recycle confirmation" in Explorer (or Shift-Del).
Malware Warning Information: Exercise due diligence, but understand that the required behaviour of this application will trigger some anti-malware engines which look for suspicious behavior, such as tampering with Windows Explorer. You may see warnings on this site or from your own software. Review them, but watch for 'trojan.generic' or 'gen.trojan.heuristic' types of identifiers from antivirus engines, which denote that the file does not necessarily contain identifiable harmful code, but exhibits a potentially unwanted behaviour, which is expected and desirable in most cases. Understand however, that this doesn't mean this download cannot become unsafe, infected with real malware, like other software, so read the warnings from your scanning engines to be sure.
