Public Enumeration FileAttributes
public enum FileAttributes


Member name Description
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.


You can get attributes for files and directories by calling the GetAttributes(String) method, and you can set them by calling the SetAttributes method.

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