Portable can embed a script to restore key from encrypted file. | | Multiple USB drive letters | Use %CD% in batch script; detect drive via %~d0 . | | Save games & profiles | Redirect Save folder to local USB path via junction or custom War3Preferences.txt . | | Windows 10/11 Virtualization | USB drive must be NTFS or exFAT (FAT32 can’t store files >4GB — War3x.mpq is ~400MB safe, but custom maps may exceed). | warcraft 3 frozen throne portable
