Quotas and converted NTFS volumes

Disk quotas work with all NTFS volumes on computers running the Windows 2000, the Windows XP, or the Windows Server 2003 family of operating systems. However, files on volumes that have been converted from FAT or FAT32 to NTFS automatically belong to the administrator, and so quota on these files are charged against the administrator account. This is seldom a problem because administrators have unlimited volume use. This issue only applies to files that existed before conversion to NTFS; files created after conversion belong to the appropriate user.

Because disk quotas are based on file ownership, any changes to a volume that affect ownership status of the files on it, including file system conversion, might affect disk quotas for the volume. Therefore, you should understand the changes to ownership that the conversion might cause before converting existing volumes from one file system to another. For more information about file ownership issues, see Deleting disk quota entries.

For more information about file system compatibility and limitations, see Choosing a file system: NTFS, FAT, or FAT32.
