in iOS 8, multiple entries of "Local Disk" spawned every time I use Windows 7 File Explorer to transfer files to my computer.
How to remove those? and when will iPhone / iOS re-index those random sub-folders in DCIM folder?
Settings > Safari > Advanced > Website Data > Remove All Website Data
Worked for me with iOS 8. Disconnect then reconnect the phone to the PC and all the "Local Disk" rubbish is gone.
If you don't want to remove all website data then do as follows: Settings > Safari > Advanced > Website Data > then Edit and proceed to erase each entry looking similar to this "a####.phobos.apple.com" . No more "Local Disk" and even erased the empty folders. It worked for me.
