Quick Answer
Your .mcaddon or .mcpack file imported but doesn’t appear in Minecraft because the file extension was likely renamed during download (Safari/iOS and Chrome/Android often rename .mcaddon to .zip or .mcaddon.zip), or the pack’s min_engine_version exceeds your Minecraft version. Rename the file back to .mcaddon, clear Minecraft’s import cache folders, and verify the manifest.json version matches your game.
Common Root Causes
- Extension renamed by browser: Safari on iOS and Chrome on Android silently rename
.mcaddon→.mcaddon.zipor.zip. Minecraft won’t recognize these. - Corrupted/incomplete download: Files under ~50 KB for large packs are likely truncated.
- Version mismatch:
manifest.jsonspecifiesmin_engine_versionhigher than your installed Minecraft version (e.g., pack requires 1.21.20 but you’re on 1.21.10). - Stale import cache: Old folders in
com.mojang/behavior_packsandresource_packsconflict with new imports. - Double-import bug: Behavior and resource packs split but only one activates in the UI.
Step-by-Step Fixes
1. Fix the File Extension (Most Common Fix)
Android: Use a file manager (Files by Google, MiXplorer) → locate the downloaded .mcaddon.zip or .zip → rename to .mcaddon → tap to open in Minecraft.
iOS (iPhone/iPad): Safari renames to .zip. In Files app → On My iPhone → Downloads → long-press file → Rename → change extension to .mcaddon → tap → “Open in Minecraft.”
Windows 10/11: Show file extensions (View → File name extensions) → rename pack.mcaddon.zip to pack.mcaddon → double-click.
2. Clear Minecraft’s Import Cache
Delete these folders (they regenerate on next launch):
# Android
Android/data/com.mojang.minecraftpe/files/games/com.mojang/behavior_packs/
Android/data/com.mojang.minecraftpe/files/games/com.mojang/resource_packs/
# iOS (via Files app → On My iPhone → Minecraft → games → com.mojang)
com.mojang/behavior_packs/
com.mojang/resource_packs/
# Windows 10/11 (Microsoft Store version)

esource_packs\3. Verify manifest.json Version
Rename .mcaddon → .zip → extract → open manifest.json in the header object. Check min_engine_version matches or is below your Minecraft version:
// Example: pack requires 1.21.20 (v26.0+)
"min_engine_version": [1, 21, 20]
// Your game version: Settings → Profile → Version4. Check Both Pack Tabs
After import, go to Settings → Global Resources AND Behavior Packs in world settings. Some packs split into separate behavior + resource packs — both must be activated.
Still Not Working?
Read the content_log.txt in the same com.mojang folder for error details. Search for [Error] or your pack’s UUID.
