Alphaleonis.Win32.Filesystem Namespace |
The Filesystem namespace contains classes to access and work with the local filesystem. Many of the classes in this namespace are replicas of the ones available in the System.IO namespace, but with added functionality. All methods in this namespace accept long windows unicode paths (i.e. paths starting with \\?\).
Additional classes and methods are provided to provide more advanced functionality than that of System.IO.

| NotSameDeviceException | [AlphaFS] The exception that is thrown when an attempt perform an operation across difference devices when this is not supported. |
| Path | Performs operations on String instances that contain file or directory path information. These operations are performed in a cross-platform manner. |
| SafeFindFileHandle | Represents a wrapper class for a handle used by the FindFirstFile/FindNextFile Win32 API functions. |
| SafeFindVolumeHandle | Represents a wrapper class for a handle used by the FindFirstVolume/FindNextVolume methods of the Win32 API. |

| TransactionalConflictException | [AlphaFS] The function attempted to use a name that is reserved for use by another transaction. |
| TransactionAlreadyAbortedException | [AlphaFS] It is too late to perform the requested operation, since the Transaction has already been aborted. |

| TransactionException | [AlphaFS] The exception that is thrown when an attempt to create a file or directory that already exists was made. |
| UnrecognizedReparsePointException | [AlphaFS] The function attempted to use a name that is reserved for use by another transaction. |

| VolumeInfo | Contains information about a filesystem Volume. |
Structures| Structure | Description | |
|---|---|---|
 | AlternateDataStreamInfo | Information about an alternate data stream. |
| FileIdInfo | Contains information that the GetFileInformationByHandle function retrieves. |
| Shell32FileInfo | SHFILEINFO structure, contains information about a file system object. |
Delegates| Delegate | Description | |
|---|---|---|
 | CopyMoveProgressRoutine | Callback used by CopyFileXxx and MoveFileXxx to report progress about the copy/move operation. |
| ErrorHandler | [AlphaFS] Represents the method that will handle an error raised during retrieving file system entries. |
Enumerations| Enumeration | Description | |
|---|---|---|
 | CopyMoveProgressCallbackReason | Used by CopyFileXxx and MoveFileXxx. The reason that CopyMoveProgressRoutine was called. |
| CopyMoveProgressResult | Used by CopyFileXxx and MoveFileXxx. The CopyMoveProgressRoutine function should return one of the following values. |
| CopyOptions | Flags that specify how a file or directory is to be copied. |
| DeviceGuid | System-Defined Device Interface Classes |
| DirectoryEnumerationOptions | [AlphaFS] Directory enumeration options, flags that specify how a directory is to be enumerated. |
| DosDeviceAttributes | Defines the controllable aspects of the Volume.DefineDosDevice() method. |
