System.IO.FileAttributes Enumeration

Description

The attributes here are mutually exclusive (except for Normal) and may be applied in any combination (it has the [FlagsAtribute], and so, in Delphi terms, is really a Set).

Some are not applicable to directories.

Values

ReadOnly	1	The file is read-only.
Hidden	2	The file is hidden, and thus is not included in an ordinary directory listing.
System	4	The file is a system file. The file is part of the operating system or is used exclusively by the operating system.
Directory	16	The file is a directory.
Archive	32	The files archive status. Applications use this attribute to mark files for backup or removal.
Device	64	Reserved for future use.
Normal	128	The file is normal and has no other attributes set. This attribute is valid only if used alone.
Temporary	256	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.
SparseFile	512	The file is a sparse file. Sparse files are typically large files whose data are mostly zeros.
ReparsePoint	1024	The file contains a reparse point, which is a block of user-defined data associated with a file or a directory.
Compressed	2048	The file is compressed.
Offline	4096	The file is offline. The data of the file is not immediately available.
NotContentIndexed	8192	The file will not be indexed by the operating systems content indexing service.
Encrypted	16384	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.
