title: Significance of file wc.db in SVN
body: <p>I am moving some websites from TFS to SVN control. The svn repositories are just on my local machine for now. I may have accidentally put one website into an already existing local repository but I am not sure.</p>
  
  <p>To find out, I checked out the particular website again into a new svn repo via tfs2svn and did a winmerge between it's working directory and the working directory of the repo I may have messed up. The win merge told me that they are exactly the same except for the wc.db binary file in the .svn folder. Since much google searching has not yielded what this file does I have 3 questions:</p>
  
  <p>1) What is the purpose of wc.db? 
  2) What information does it store?
  3) Most importantly: based on the above answers, if all files in 2 repositories are the same except for this wc.db file, can I or can I not consider the 2 repositories to be identical?</p>
