RAR and ZIP files

How can I make YACreader read ZIP or RAR files?
Scanning my comics folder doesn't add them to the library or can't read them. Neither on the PC, nor on my Android tablet.
Do I have to activate any option?

Thank you in advance.

Hmmm,

there is nothing you need to do. YACReaderLibrary will detect the files on every scan.

What is there inside these files? If the apps don't find any image files the won't consider them valid comic files.

Hola,
Muchas gracias por contestar.
Problema solucionado. Lo que tenía dentro de los RAR eran otros archivos CBR o CBZ y claro, YAC reader sólo los lee en el caso de que contengan imágenes.

Un saludo y gracias de nuevo.
