tdms-files: Is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files?

[Baui]

Hello,

is it possible to prevent LabVIEW and DIAdem from creating .tdms_index files when opening/creating/editing a .tdms file?

I think I have no benefit from the .tdms_index files because our applications create a lot of little .tdms-files (repeat measurements). With the additional .tdms_index files we have unnecessary memory consumption and it takes longer for Windows to open the containing folder. Also it´s confusing when searching for a certain file.

Best Regards

Daniel

Hi Baui,

I'm afraid there's a direct way to disable creating .tdms_index file now from LabVIEW and DIAdem. You can use TDMS Advacend API in LabVIEW, which doesn't create any index file, or you can just make some simple programming and delete the .tdms_index file after closing the TDMS file. 

This is a request for a long time, we'll consider to add this feature for TDMS in future releases.
