Calculate .tdms file size

[ASTDan]

Hello,

I am trying to find a formula the aproximates the size of a .tdms file on disk.

I am mulling over a few ways to set up my files and having a way to estimate file sizes would be helpfull.

Does anyone know of a good method to do this?

Thanks

Dan

Hi Dan,

I don't have an answer for you, but you should look at:

Why Are My TDMS Files So Large?

I found that when dealling with files that are really large (GBs) TDMS format was not usable. It takes too long to degragment, HD space runs out (when defragging a second file is created to contain the output of the defrag, so you have the original file and the defrag output file while processing), opening the TDMS file takes alot of time when not defragmented.

Thanks Denis,

It looks like the best answer to my question is to generate some data in the file format I think would work and see how it performs. Thanks for letting me know about some of issues when large files are generated. I am almost sure I will run into those.
