Issue Details

I receive Error 7 when I try to use a VI that is referencing a filepath.

Error 7 occurred at Open File+.vi:Open File

Solution

This error occurs when the specified path does not exist. This file will not create a path for you; for example, if the path specified is C:\Data\Today\Document1.xls and there is no Today folder in C:\Data , this error message will occur. To fix this, manually create the appropriate directory.


 

Additional Information

You could also programmatically create the folder if it is not found as shown below. This example is also posted as an example on the NI Developer Community and the link can be found in the related links section.



Note: This error can occur with any File I/O VI or other function that might require a file path input and is not specific to the Read Characters From File VI.
