|Archive||The file's archive status. Applications use this attribute to mark files for backup or removal.|
|Compressed||The file is compressed.|
|Device||Reserved for future use.|
|Directory||The file is a directory.|
|Encrypted||The file or directory is encrypted. For a file, this means that all data in the file is encrypted. For a directory, this means that encryption is the default for newly created files and directories.|
|Hidden||The file is hidden, and thus is not included in an ordinary directory listing.|
|Normal||The file is normal and has no other attributes set. This attribute is valid only if used alone.|
|NotContentIndexed||The file will not be indexed by the operating system's content indexing service.|
|Offline||The file is offline. The data of the file is not immediately available.|
|ReadOnly||The file is read-only.|
|ReparsePoint||The file contains a reparse point, which is a block of user-defined data associated with a file or a directory.|
|SparseFile||The file is a sparse file. Sparse files are typically large files whose data are mostly zeros.|
|System||The file is a system file. The file is part of the operating system or is used exclusively by the operating system.|
|Temporary||The file is temporary. File systems attempt to keep all of the data in memory for quicker access rather than flushing the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.|
