About comparing versions of elements

As you modify source files, you may want to compare versions to answer questions such as these:

• What changes have I made in my checked-out version?
• How does my checked-out version differ from a particular historical version or from the version being used by one of my team members?

• To compare a version with its predecessor
  
• To compare with a version other than the predecessor
  
• To compare any two files (Windows)
