Did you install an additional Source Plugin?

Comic CBR, CBZ Viewer - Chrome App.
I'm in the same boat. Currently I have them loaded on an external hard drive connected to my router. I can then access the SMB share through Perfect Viewer and read the comics. This is a bit faster than my previous solution of loading them all on Google Drive and connecting Perfect Viewer to that.
Edit - here's the link for the Perfect Viewer source plugin (needed for Drive or SMB) - https://play.google.com/store/apps/details?id=com.rookiestudio.perfectviewer.plugin.source&hl=en
