Moving one of the sounds in library manager failed

Hi, Not sure if this is a big deal. I have moved all my stuff on the library manager over to external hard rive and a named my folders after the sound content. I wrongly named the retrologue folder retrologue 2 . When I tried to change it and move it failed. I lost the file so reinstalled with the download manager but I still can’t move it off my internal hard drive. a bit OCD but would like some help or reassurance. thanks
