title: Disk space for windows subsystem for linux (in case I have installed 2 WSL distribution)
body: <p>I have accidentally installed two distribution of WSL (Ubuntu and Debian apps), with both built some software. </p>
  
  <p>I then realize that the <code>/home/usr</code> of the two are independent of each other, eg. I could not use Ubuntu to access the files that I placed in <code>/home/usr</code> using Debian. Is it there are different <code>/home/usr</code>?</p>
  
  <p>Are there any limitations of disk space allocated to the subsystem? Or we can install programs or data as long as we have disk space in our pc? 
  (As previously I used virtual machine and there was a place to let us allocate limited disk storage to them)</p>
  
  <p>And are there any bad consequences if I continue to keep these two WSL distribution on my pc? Or I should delete either one?</p>
  
  <p>Any advice are highly appreciated! Thank you :)</p>
