Since you don't mention what functions you're using, I'm going to assume that they're Write Characters to File or Write to Spreadsheet file and their associated read functions. Inside these functions is the General Error Handler that pops up a dialog when an error occurs. The Open/Create/Replace functions defines a cancel as error code 43. To remove the pop-up, modify the functions you're using and remove the general error handler. Save the modified VIs with a different name and to a new location. You can then do your own trapping of error code 43.

You can also modify these VIs so that you can provide an input to the pattern input of Open/Create/Replace. If your files have a unique extension, then you would at least limit the files displayed to the user to those with that extension.
