Copying files in Copywhiz when a file with the same name already exists

Question

During a paste operation through the main form of the program (launched via a pre-loaded project.xml), sometimes an error message pops up :
"File X of source and Y of destination (same file name) are "equal" : Skip or replace ?"
Now, if the two are equal, does it make sense to replace ? And in what context are two files considered similar- By it's content, by date-size or what?

Answer 1

 Copywhiz  only checks the file modified date and file size. If both are same then it thinks that the files are equal/identical. So you may want to skip that operation instead of replacing the file.

Also, you can automatically rename duplicate files if such a message pops up.
