How to change a default reading app on pocketbook inkpad 4?

mhthero · 01-05-2026, 08:12 AM

Hello! I've downloaded Edit Book Info - PocketBook script from here to be able to edit book info. It worked fine, but now I have a problem with opening books. It was set as a default reading app after the last update and because of that every time I'm trying to open a book it just opens the edit info window. I can open books using "open with" function, but it's not really convinient. How can I change the default reading app back to pb reader?

Probably you have to edit or copy to ereader's memory file called extensions.cfg. It shoul contain line like „epub:@EPUB_file:1:eink-reader.app:ICON_EPUB”. Such file will allow to use only default reader. If you want to have a choice under "open with" pop-up menu, there should be a link to this script as well. But I don't know what kind.
Anyway probably there is extensions.cfg in your „system/config” directory. Maybe you have to edit it and put "eink-reader.app" at the beginning of „epub:" line instead of this new script.
