This follows on from a post in another thread.
Consider two different hard drives. The same files are saved on each HDD but with different names and there is a requirement to synchronise the file names on both drives without having to do it file by file. Where there are a large number of folders with a reasonable number of files in each folder, setting up a .csv or .txt file for each folder is labor intensive.
One possible approach is to select and copy file names from one drive and replace/paste file names on second drive, after shifting focus in BRU to the second drive.
Another is a split window showing both drives, files highlighted in each window accompanied by a copy file name only and transfer direction commands.
