Actually, the latest version of the itch app does support rar (contrary to what this post suggest, I should edit it) — updating to the latest version of the itch app should fix that problem :) You can download it from https://itch.io/app or simply let the itch app self-update on Windows & Mac.
Thanks for the quick response, but I believe we've had a miscommunication. It's very clear that you will never support RAR and I think that makes sense. That's not at all what I'm asking about. The problem I'm experiencing is the Itch App is hounding me every few minutes if a game I have subscribed to is packaged up by its developer in RAR format. It's popping up the same error on my screen every five minutes or so, interrupting my work and my twitch stream.
In other words, this is a request for you to disable this error message within the Itch App. Please. I see no reason to punish all users. Why not just prevent the RAR packaged game from operating and mark it with an icon or a link to more info? This is simply a complaint about repetitive pop up errors in the Itch App.
Let me try this again:
- this post suggests .rar is not supported
- in some previous versions of the app, a bug existed where if the 'best upload' became a .rar file (which I suppose is what you're seeing), then it would show the "RAR is not supported" on every update check (30 minutes)
- .rar support was actually added in 18.5.0
- this fixes the above issue, since the "RAR is not supported" dialog doesn't exist anymore, and the itch app will now simply extract the .rar archive instead of complaining
- please update to the latest of https://itch.io/app
(Also, I'm curious why your itch app didn't auto-update — are you on Linux?)
