noob question... is this the right procedure to copy a whole file folder to phone e.g. acoustic file to acoustic FS in phone >> left window of jdflasher >> browse/select the folder >> press F5 >> type to "Copy to" /ifs/setting/acoustic >> press copy.

e.g. acoustic file folder to copy - 45 files and phone acoustic folder existing 50 files. Thus procedure above will delete/replace phone acoustic folder or it will just overwrite old file and will not delete the other data(s) in my phone. Is there any other way to multiple select?
