Issue Details

I have multiple TDMS files generated on my application that share the same channels and groups names and I want to concatenated each channel with your respective peers of the other files and create a single TDMS file with those. 
How can I do that?


There are some possible solutions for that issue depending on your needs. 

Using LabVIEW:

Using DIAdem

Additional Information

You can also merge DIAdem files by using the following syntax in a DOS shell:
copy /b "Path to the first TDMS file" + "Path to second TDMS file" + ... + "Path to n TDMS file" /b "Path to the resulting TDMS file"
for example:
copy /b "C:\Test merging tdms\File 0.tdms" + "C:\temp\Test merging tdms\File 1.tdms" + "C:\temp\Test merging tdms\File 2.tdms" /b "C:\temp\Test merging tdms\Resulting file.tdms"
