Just a Reminder to DLINK. Hopping it will not be forgotten in a futur release...
Here the bug : If you are using the Download manager to download from one disk to the other, larger are you're structure, more the error are...
I notice some folder not copied, some file not copied, and sometime, some folder name not copied correctly.
If you create a log for each "successfull or un-successfull" file/folder copied, it will help finding where the download manager stop working...
For now, we cannot rely on this manager because it's not safe for data.
