Transferring files PC to Xbox.

[Sausage]

If I create a modded .DAT File on my PC can I move it to an Xbox game that is stored on an external USB drive?

I have a character file on my PC from minecraft dungeons. Im wondering if the xbox game file can be accessed via PC and if it uses .DAT files for the character like the PC does. I would try it but I don't have an external drive yet so thought I'd ask first.

Was going to try this. I feel like it's inaccessible cause someone surely would have tried but I heard Minecraft worlds were importable at one point. Apparently the native file explorer app was removed from the Store but you can still access it using a third-party app I heard.
Will try soon.

Unfortunately they do not give you access to games files, only some app files, probably for this reason.

Your only option is Microsoft Store PC Games.
