Thanks for the tip. I was able to copy all the music files from NAS drive Y:\ (music files in directory order by artist) to the new drive which is local D:\.
OK, so the files themselves have been copied successfully to the right place? If so, great.
When I try to do any sort of manipulation selecting files currently in the library and moving them from Y:\ to the local "D" drive, MC doesn't restore the original directory structure but, rather, places all 20k+ files in the root directory of that drive.
I assume you're just trying to update MC and not use MC to actually copy or move files. Because the files are already copied right? If so, we need to use RM&C in UPDATE mode. That's at the top of the RM&C tool.
Next, uncheck Directories and Filename. Do CHECK Find & Replace. Then, in the find and replace section:
Find What: Y:\
Replace with: D:\
That will replace the drive letter with the new one. If the leading path has changed, you can alter the find and replace values so the correct directory is used.
Notice that there's a preview window off to the right that shows what's going to happen. Look at the preview and make sure it looks correct before you press OK. If it's not correct, change values until it is.
Brian.
