Issue Details

I was running and recording a DAQExpress Task. Midway through the recording my computer crashed or DAQExpress crashed. Is there any way to recover the data that I have been recording?


When Record or Record (Timed) is selected for a DAQExpress Task as shown in Figure 1, data is periodically written to a temporary TDMS file located in C:\Users\[User-account]\AppData\Local\Temp\NI Project Data\[project-instance-unique-identifier-name]**.

Not all data is likely to be recovered, but the data since the last write to the temporary file may be recoverable. 

AppData folder is hidden by default.  You can access the hidden directory by showing hidden folders on your computer or by navigating to it using the method below:
  1. Open Windows Run by navigating to Start Menu » Run or by using the keyboard shortcut Windows Key + R.
  2. Type in %TEMP% and hit the Enter button.
