File System

    Last Modified: August 30, 2018

    LabVIEW mounts USB devices and microSD cards to the media/sdx1 directory and creates symbolic links /u, /v, /w, or /x to the media mount point, starting with /u if it is available. To prevent any file corruption to external storage devices, verify that any file IO operations with the specific drive finish before removing the device. Refer to the LabVIEW Help for more information.

    The file system of the cRIO-905x follows conventions established for UNIX-style operating systems. Other LabVIEW Real-Time targets follow Microsoft Windows-style conventions. In order to facilitate the porting of applications from those targets, this target supports the Windows-style /C home directory. This path is bound to the UNIX-style directory /home/lvuser.

    Various LabVIEW Real-Time system files which would be accessible from C: (or /C) on other LabVIEW Real-Time targets are found in different locations on this target.

    UNIX-style file systems support the concept of a symbolic link, which allows access to a file using an alternative file path. For example, it is possible to link /C/ni-rt/system, where dynamic libraries are deployed on other LabVIEW Real-Time targets, to /usr/local/lib, where they are stored on the cRIO-905x, if the application requires this.
