Unlocker application was designed to be very useful for Windows Explorer extension allowing users with a simple right-click the file or folder to easily get rid of error message such as error deleting file or folder, do not delete folder: it is currently used. Helps delete locked files with error messages like: Can not delete file: Access is denied There sharing injury. The source or destination file may be in use. This file is in use by another program or user. Make sure the disk is not full or write-protected and that the file is not currently in use. Note: Some antivirus and anti-spyware program Unlocker is flagged as infected / malware, although the application is perfectly safe and does not pose a threat to your system. This is called a false positive. The term false positive is used when antivirus software wrongly classifies a simple (inoffensive) file as a virus. The incorrect detection may be due to heuristics or incorrect virus signature database. [Similar problems can occur in antitrojan or anti-spyware software.]
