title: Unique file ID in FAT32
body: <p>Development environment: mobile app in Android</p>
  
  <p>I'm looking for a way to uniquely identify files in a FAT32/VFAT file system (which has no inodes).
  I thought about hashing (SHA1?) the full path. The problem with this solution is that it doesn't support moving/renaming.</p>
  
  <p>Is there something better, that will hold even when moving/renaming the file?</p>
  
  <p>Thanks</p>
