I have two folders, each of which contains many other folders. Let's call FOLDER 1 the first and FOLDER 2 the second... FOLDER 2 could also be one Hard Disk... I would copy the folders that are in FOLDER 1 in the FOLDER 2 folder (or HARD dISK...) If there is a folder that has the same name, it should not be copied and must be left in FOLDER 1... If does not exist, must be copied to FOLDER 2 and deleted from FOLDER 1......... You think it's possible with you program CopyWhiz? The problem is that with Windows, the folder with the same name is not copied (superimposed) but the files it contains, if they have different names from those contained in the folder to be copied, are copied too!
