Tds Error: TdsErrNotTdsFile(-2503)

Go to solution



I have a cRio that records data in the tdms file format. After testing last night, I tried to open one of the files but got the error described in the subject line. After searching around it looks like NI might be able to recover some of the data file. Is this possible?

How big is the file.

Can you upload it to ftp?

Hi NeedDIAdemHelp,


I'm fairly certain that the person who recovered the TDMS file before referenced this White Paper. I'd try using that to recover the file yourself if possible.


If you have trouble with that, feel free to post again, and we'll see what we can do!


By the way, I like your username!

Hi Andy,


I was able to use that white paper to fix the file. Thanks!


I'm glad you like the username....I thought it was fitting.
