Robocopy Log File Meaning of New File, New Dir

Example log:

*EXTRA Dir        -1    y:\Open Client Files\sample\
                   0    f:\server\blah\somefolder\
                   6    f:\server\blah\somefolder\

The numbers (-1, 0, 6, etc.) are the number of files in that folder. -1 is used for "Extra Dir" entries, and 0 is used for "New Dir" entries (and other folder without any files in them).

Note this number is a count of only the files in the folders, and does not include sub-folders that may be in the folder.

"New Dir" represents a folder that existed on the source but not in the target, and "Extra Dir" represents a folder that existed in the target that wasn't in the source.

"New File" and "Extra File" are the same thing, only for files. :)

"Extras" will be removed if you're using options like PURGE and MIR.
