Minecraft Java Edition

Minecraft Java Edition writes rotating game logs, JVM and launcher diagnostics, saved crash reports, and a Chromium-based launcher webcache2 directory that stores HTTP cache files, cookies, GPU cache data, and local web assets for the news feed, account pages, and embedded storefront views. These files build up through normal play, mod loading, sign-in attempts, updates, and launcher browsing, but they are not required to keep worlds, resource packs, saves, accounts, or settings. Kudu removes old logs, crash-reports, and stale launcher web cache so the game and launcher can rebuild only what they still need.

Why clean Minecraft Java Edition?

  • Launcher webcache2 can retain stale account and storefront assets, causing a blank Home tab, missing news images, or sign-in pages that never finish loading until the cache is rebuilt.
  • Chromium GPU cache data inside webcache2 may be invalidated after a graphics driver update, which shows up as black panels, flickering launcher content, or sluggish scrolling in embedded pages.
  • Repeated mod crashes and failed launches leave behind many hs_err, latest.log, and crash-report files, making the .minecraft folder grow noticeably and harder to inspect when a new problem happens.
  • Very large logs from verbose mod loaders, shader packs, or repeated connection errors can consume hundreds of megabytes and cause text editors or log viewers to hang when opening the newest session output.
  • Old crash-reports preserve stack traces for problems that are already fixed, so users can end up chasing outdated errors instead of the current one when troubleshooting startup or world-load failures.
  • Corrupted cached web resources in the launcher can trap it in a loop where library pages partially load, buttons do nothing, or the Microsoft login view refreshes repeatedly.
  • Clearing these targets removes disposable diagnostics and browser cache only, so worlds, screenshots, saves, mods, resource packs, settings, and account credentials remain untouched.
