3/26/2014

The following table shows the file system I/O functions implemented by file system drivers (FSDs) with a description of the purpose of each.

Function	Description
MyFSD_CloseFile	Called when an application closes an open handle for a file that is open on an installable file system.
MyFSD_CloseVolume	Closes a volume on a device that has an installable file system.
MyFSD_CreateDirectoryW	Called by FSD Manager to create a new directory in an installable file system.
MyFSD_CreateFileW	Creates, opens, or truncates a file, pipe, communications resource, disk device, or console in an installable file system.
MyFSD_DeleteAndRenameFileW	Deletes a file after it copies its contents to a destination file in an installable file system.
MyFSD_DeleteFileW	Deletes a file from an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop platform function DeleteFile. FSD Manager determines the file system type and calls the MyFSD_DeleteFileW implementation of the function.
MyFSD_DeviceIoControl	Sends an I/O control directly to a specified device driver, causing the corresponding device to perform the specified operation. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop platform function DeviceIoControl. FSD Manager determines the file system type and calls the MyFSD_DeviceIoControl implementation of the function.
MyFSD_FindClose	Closes the specified search handle. The MyFSD_FindFirstFileW and the MyFSD_FindNextFileW functions use the search handle to locate files with names that match a specified name. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop platform function FindClose. FSD Manager determines the file system type and calls the MyFSD_FindClose implementation of the function.
MyFSD_FindFirstFileW	Searches a directory a specified file. This function also examines subdirectory names. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function FindFirstFile. FSD Manager determines the file system type and calls the MyFSD_FindFirstFileW implementation of the function.
MyFSD_FindNextFileW	Continues a file search from a previous call to the MyFSD_FindFirstFileW function. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function FindNextFile. FSD Manager determines the file system type and calls the MyFSD_FindNextFileW implementation of the function.
MyFSD_FlushFileBuffers	Clears the buffers for the specified file in an installable file system and causes all buffered data to be written to the file. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function FlushFileBuffers. FSD Manager determines the file system type and calls the MyFSD_FlushFileBuffers implementation of the function.
MyFSD_FsIoControl	Can be exported by an FSD and processes I/O controls for a file system volume. The application does not call this function directly. Instead, use the corresponding standard function CeFsIoControl. FSD Manager determines the file system type and calls the MyFSD_FsIoControl implementation of the function.
MyFSD_GetDiskFreeSpaceW	Obtains information about the amount of space available on a disk volume in an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function GetDiskFreeSpaceEx. FSD Manager determines the file system type and calls the MyFSD_GetDiskFreeSpaceW implementation of the function.
MyFSD_GetFileAttributesW	Obtains attributes for a specified file or directory in an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function GetFileAttributes. FSD Manager determines the file system type and calls the MyFSD_GetFileAttributesW version of the function.
MyFSD_GetFileInformationByHandle	Obtains information about the specified file in an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function GetFileInformationByHandle. FSD Manager determines the file system type and calls the MyFSD_GetFileInformationByHandle implementation of the function.
MyFSD_GetFileSize	Obtains the size, in bytes, of the specified file in an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function GetFileSize. FSD Manager determines the file system type and calls the MyFSD_GetFileSize implementation of the function.
MyFSD_GetFileTime	Otains the date and time at which a file in an installable file system was created, last accessed, and last modified. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function GetFileTime. FSD Manager determines the file system type and calls the MyFSD_GetFileTime implementation of the function.
MyFSD_LockFileEx	Locks a region of the specified file for exclusive access by the calling process.
MyFSD_MountDisk	Mounts the specified disk containing a file system of the type defined by an FSD. This function is exported by an implementation of an FSD and is called indirectly by FSD Manager.
MyFSD_MoveFileW	Renames a file or directory, including all its children, that resides in an installable file system. The application does not call this function directly. Instead, use the corresponding standard Windows-based desktop function MoveFile. FSD Manager determines the file system type and calls the MyFSD_MoveFileW implementation of the function.
MyFSD_ReadFile	Reads data from a file, starting at the position indicated by the file pointer.
MyFSD_ReadFileWithSeek	Reads data from a file, starting at the position indicated by the caller.
MyFSD_RemoveDirectoryW	Deletes an empty directory from an installable file system.
MyFSD_SetEndOfFile	Moves the end-of-file (EOF) position for the specified file in an installable file system to the current position of the file pointer.
MyFSD_SetFileAttributesW	Sets the attributes of a file that resides in an installable file system.
MyFSD_SetFilePointer	Moves the file position of an open file in an installable file system.
MyFSD_SetFileTime	Sets the date and time at which a file in an installable file system was created, last accessed, or last modified.
MyFSD_UnLockFileEx	Unlocks a region in an open file. Unlocking a region enables other processes to access the region.
MyFSD_UnmountDisk	Unmounts the specified disk containing a file system of the type defined by an FSD.
MyFSD_WriteFile	Writes data to a file in an installable file system at the position indicated by the file pointer.
MyFSD_WriteFileGather	Gathers data from a set of buffers and writes it to a file.
MyFSD_WriteFileWithSeek	Writes data to a file in an installable file system, starting at the position indicated by the caller.
