How do I open/view Signal Express Data .tdms files? (Absolutely Brand New User!)

[efktechsupport]

Hi everyone,

I've inherited this data recording software from a previous engineer and tried it out for the first time the other week. Mind you I have no manuals or help really here, so bear with me that this is probably a very basic question.

I had a set-up using the Labview Signal Express ver.2.5 and NI-USB-6008 monitoring two voltages. I currently want to see the playback of the .tdms files which are located in my C:\Documents and Settings\TechSupport\My Documents\SignalExpress Data\08042009_015232_PM folder (3 files, voltage.tdms, voltage.tdms_index, and voltage_meta). I opened LabVIEW Signal Express and clicked "File", "Import", "Logged Signals From SignalExpress TDMS Files", and go to select the "voltage.tdms" file, but receive the error of "You cannot choose this folder name; a file of that name already exists".

Does anyone know what I'm doing wrong?

Thanks for any and all help (and let the sarcastic comments begin 🙂 )

Would you mind attaching what you have so far so we can take a look at it?

Is there a limit to what size file can be posted? The zipped version of the three files mentioned above is 82.1 MB.

Sometimes, selecting current folder instead of open is a valid workaround. 

Also, can you identify the program responsible for creating the log data? Are you able to view this data using another progarm like LabVIEW or DIAdem?

I believe the SW installed is NI-DAQmx and the program recording the data at the time was LabVIEW Signal Express. Since it was recording over extended periods of times, the log would be cleared (running out of disk space) and the recording restarting. Because of the this, the project was never saved, but the .tdms files do exist in the "SignalExpress Data" folder.

Have you tried selecting CURRENT FOLDER instead of open?
