    how to recover .npsk file

  6. AvatarHugo

    Paso 1: panel de control, opciones de carpeta, ver, tilden mostrar archivos, carpetas, etc.
    Paso 2: en la carpeta infectada les va a aparecer: elarchivo.extension.npsk Ejemplo thebeatles.mp3.npsk

    Modificacion manual: borran la ultima parte de la extension, deberia quedar thebeatles.mp3

    Modificacion automatica: crean un archivo .bat

    Abre un bloc de notas y escriben lo siguiente (se necesita un .bat por cada tipo de archivo que quieran recuperar):

    Ren *.npsk *.mp3

    Guardar como…

    Le ponen el nombre que quieran.bat

    Y lo guardan en la carpeta que quieran cambiar la extensión.

    Entran a la carpeta, doble click en el nuevo archivo que crearon y listo.

    Eso lo tienen que hacer en cada carpeta que este infectada.
