If File Exists in Destination

What should be done if a file being installed already exists on user's hard drive.
Skip - do not extract the file.
Overwrite - overwrite the existing file.
Overwrite if newer - overwrite the file only if the file is newer or has a later version than the already existing one.
Ask - prompt the user to select an appropriate action.
Ask if newer - request directions from user only if the file is newer or has a later version than the already existing one. Otherwise, the file will be skipped.
Notice! If a file must be updated but is locked by the system or by other applications, at the end of installation, the user will be asked to reboot the computer. Such files will be updated after the reboot.
