title: Folders randomly dissapear in Eclipse's workspace
body: <p>I'm currently working in a Java project using Eclipse. One day my complete sprites folder saved in .../workspace/[project name]/bin/ randomly disappeared. I searched in my recycle bin, other folders, and even used a program to restored deleted files from my PC and there was no trace of the folder or missing files. I lost a lot of work and hours and got really really mad, so I learned that I had to save backups everywhere.
  Some minutes ago I was working in my project again, I rebooted my computer and it happened again. I have backups, yes, but it's getting very annoying.</p>
  
  <p>I don't know if it is right to ask this here but do you have any idea what's going on? </p>
