 Member nameDescription
Supported by the .NET Compact FrameworkArchiveThe file's archive status. Applications use this attribute to mark files for backup or removal. 
Supported by the .NET Compact FrameworkCompressedThe file is compressed. 
Supported by the .NET Compact FrameworkDeviceReserved for future use. 
Supported by the .NET Compact FrameworkDirectoryThe file is a directory. 
Supported by the .NET Compact FrameworkEncryptedThe 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. 
Supported by the .NET Compact FrameworkHiddenThe file is hidden, and thus is not included in an ordinary directory listing. 
Supported by the .NET Compact FrameworkNormalThe file is normal and has no other attributes set. This attribute is valid only if used alone. 
Supported by the .NET Compact FrameworkNotContentIndexedThe file will not be indexed by the operating system's content indexing service. 
Supported by the .NET Compact FrameworkOfflineThe file is offline. The data of the file is not immediately available. 
Supported by the .NET Compact FrameworkReadOnlyThe file is read-only. 
Supported by the .NET Compact FrameworkReparsePointThe file contains a reparse point, which is a block of user-defined data associated with a file or a directory. 
Supported by the .NET Compact FrameworkSparseFileThe file is a sparse file. Sparse files are typically large files whose data are mostly zeros. 
Supported by the .NET Compact FrameworkSystemThe file is a system file. The file is part of the operating system or is used exclusively by the operating system. 
Supported by the .NET Compact FrameworkTemporaryThe 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. 

For an example of creating a file and writing text to a file, see Writing Text to a File. For an example of reading text from a file, see Reading Text from a File. For an example of reading from and writing to a binary file, see Reading and Writing to a Newly Created Data File.

All these attributes correspond to those in WinNT.h. Not all attributes are applicable to both files and directories.

It is not possible to change the compression status of a File object using the SetAttributes method.
