ChatFS — Fast File & Folder Transfer in Minecraft

ChatFS allows players to instantly send files, schematics (.litematic), screenshots, and entire folders directly to each other inside Minecraft via in-game chat!

Key Features

  • Fast Zstd Compression: Uses high-performance native Zstd compression (up to 3 GB/s) for ultra-fast transfers.
  • In-Game Media Previews: Full-size image viewer with a built-in Paint editor (draw arrows, circle coordinates, erase, and undo before sending).
  • Embedded Video Player: Watch MP4 and MOV videos directly in-game with hardware-accelerated playback, timeline scrubbing, volume controls (mouse wheel / arrow keys / M to mute), OSD indicator, and auto-muting game music.
  • Smart Video Compression: Automatically compresses large videos (>100 MB) down to ~85 MB with high-speed H.264 using FFmpeg (with 1-click automatic FFmpeg installer in settings).
  • Clipboard Integration: Press Ctrl+V in chat to instantly attach screenshots (Win+Shift+S / PrintScreen), video clips, or copied files.
  • Folder Support: Send entire folders — ChatFS automatically archives them to ZIP on the fly and unpacks them on the recipient's PC.
  • Native Windows File Picker: Select files easily using the native OS file explorer or in-game GUI (/chatfs menu or clicking the paperclip button).
  • Server Protection: Built-in anti-spam, 50 MB limit (increased up to 100 MB for video files with automatic compression), and queued stream manager to prevent server lag.

How to Use

  1. Press T to open chat and click the paperclip button, or type /chatfs menu.
  2. Select a file or folder using the Browse button.
  3. Enter recipient nickname and optional comment, then click Send!
  4. Recipient clicks [ACCEPT] in chat to save the file into their Downloads folder.
  5. Click [View] or [Watch] in chat to open images and videos right in Minecraft.
