I am moving batches of folders/files onto a new EX2 Ultra and will get this message when moving some of the folders. “You can’t copy the item “.wdmc” because its name is too long or includes characters that are invalid on the destination volume.”
I have to check each folder to see if anything is missing and then find the missing file and make the transfer.
Is there a way to prevent this from happening??
Using MacOS.

I think 256 character limit for file path/file name. (or is that infor from 10 years ago?)
Regardless. . . .after a major copy operation, I will run a folder comparision program to verify everything copied. I will rerun the copy if necessary.
I have occasionally seen problems in this area. . . .I have since been a bit more careful to trim Folder names to avoid this problem. There are probably some media file names I have also trimmed to avoid the problem going forward.
That’s not the problem.
I am having the exact same situation trying to transfer all my old music files from an older My Cloud to a new My Cloud EX2 Ultra via a Mac and I am getting the exact same result. Even if I try to drop down to individual artist folders instead of the master folder, EVERY artist fold has files that produce the “You can’t copy the item “.wdmc” because its name is too long or includes characters that are invalid on the destination volume.” error. I assume it is some character (perhaps the “space character”?) or that the Mac rewrites the file name with a character that is unsupported? I am really frustrated by the situation and my inability to find any help from WD. And I am starting to regret sticking with WD.
Joel, I ended up using a Windows PC on my network and was able to move the files with no issues. Not quite sure why it does it on my Mac, which is my primary unit, but all the files moved over and I’m back to seeing them on the Mac… Can’t say that it’s acceptable not to have WD a response, but hoping things work well from here on.
Thanks. That’s good to know. (But frustrating to realize the fix requires me to drag my 100-year old Dell out of some uncertain closet and hope I still have a power supply, in order to make this work). But thank you.
might not be the only solution but worked for me. disappointed that WD doesn’t respond with a better solution or reason this happens. -my older NAS has worked without issues which is why I kept with their product. good luck.
