TDMS Defrag Status

[steveADI]

TDMS can be a really useful format for saving large amounts of data, the problem I have is that the defrag function can take a long time to execute with no feedback to the user.  This means that there's no way way of reporting back to the user an estimate for how long the defrag will take or even whether or not it is still alive.  I understand that an estimation of the defrag time remaining may be a tall order but having a status flag reporting back that it is still active (maybe with a time stamp so you can double check it's still going) would be a great help.

Hi steveADI,

Thank you for the idea and the request. Yes, it's a little bit difficult to supply a very accurate estimation of the remained time for TDMS Defragment. However, it's really a good idea to supply some way to indicate the application is still active.

I suppose this would be a good feature to have but as a workaround and matter of habit I defrag a TDMS file after I close it.

Thaks for the comments.

Paul, yes I do defrag only after the file has been closed and then only at the end of the data gathering exercise, it'd be far too risky to start a defrag during data gathering.
