There are the following limitations:

  • You can have at most eight 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 can have a maximum of 260 characters: The file part can have at most 12 characters: eight for the file name, one for the period, and at most three for the file extension. A file name longer than eight characters is truncated to six characters followed by '~1'.

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