xPCFileSystem Class

File system drives and folders

Syntax

public class xPCFileSystem

Description

Namespace: MathWorks.xPCTarget.FrameWork

Syntax Language: C#

public class xPCFileSystem initializes file system drive and folder objects.

There are the following limitations:

  • You can have at most 128 files open on the target computer at the same time.

  • The largest single file that you can create on the target computer is 4 GB.

  • A fully qualified folder name can have a maximum of 248 characters, including the drive letter, colon, and backslash.

  • A fully qualified file name in the operating system on the target computer can have a maximum of 260 characters. If the file name is longer than eight-dot-three format (eight character file name, period, three character extension), the operating system represents the file name in truncated form (for example, six characters followed by '~1'). MATLAB commands can access the file using the fully qualified file name or the truncated representation of the name. Some block parameters, such as the Scope block filename parameter, require 8.3 format for the file name.

  • Do not write data to the private folder on your target computer. It is reserved for Simulink® Real-Time™ internal use.
