What does “replacing” mean in Tortoise SVN changelog?

Question

Once in a while I see that a file is listed in a commit in Tortose SVN changelog and the "action" column reads "replacing".

What does that mean? How is that different from "modified"?

Answer 1

From the svnbook , replacing is different from modified in the following way.

Item has been replaced in your working copy. This means the file was scheduled 
for deletion, and then a new file with the same name was scheduled for addition 
in its place.
