Temporary files like Spotfire.tsp********.txt.exe created in TIBCO Spotfire Web Player temp directories

On the TIBCO Spotfire Node Manager machine, in the Web Player services Temp folder, it may be noticed that there are .exe files getting generated, like the following example:

• \tibco\tsnm\10.10.0\nm\services\WebWorker-46.0.14925.5277-aa6341ea-56ab-4165-tb2e9-d9c5a3c81732\Temp\GAQHm6EzAk2-RhZT0C-1BA\Misc-7652\Spotfire.tspdlypg42w.txt.exe

This article explains the reason why they get generated and that these are expected. These are normal extensions and are expected when loading data out-of-process (which is the default) where Spotfire creates sub-processes internally. Generally it is seen when loading data from Microsoft Office files (xlsx, xls, mdb, and accdb) or other data sources where .tmp.exe files are used for some operations that Spotfire runs as separate processes. In this situation the data loading is handled in a separate process for increased isolation so if an error occurs it does not propagate to the main Spotfire process and risks the stability of the Web Player. 

The sub-process file in this example is Spotfire.tsp******.exe where ****** are random characters. The file name will also reflect the data source type ("txt" in the example above).
