When you copy or move NTFS files, the permissions that have been set for those files might change. The following points should be remebered while moving or copying a file.
• If you move a file from one folder to another folder on the same NTFS volume, the file will retain the original NTFS permissions.
• If you move a file from one folder to another folder between different NTFS volumes, the file is treated as a copy and will have the same permissions as the destination folder.
• If you copy a file from one folder to another folder (on the same volume or on a different volume), the file will have the same permissions as the destination folder.
• FAT partitions cannot hold permission details and if you copy or move a folder or file to a FAT partition, it will not retain any NTFS permissions.
