Hello,
Who know the where the partition names info saved on? in Registry or Disk? for example change the name from "Local Disk" to "My Disk", why sometimes the name cannot be changed in Explorer? thank you
Actually a partition doesn't have a name. A volume has a name. It is stored on the volume itself. Where .... depends on if volume has been formatted as NTFS or FAT32.
