How to crop unwated data

I have a lot of useless data at the end of a file captured when we forgot to stop recording after a test. We've captured what we wanted in the first 50% of of the data but the rest is just rubbish.

This is probably an easy task that I just cant find in the manual - How do I select a large portion of data and delete it?

Hi,

there's no direct way to delete data, but you can zoom into a region that you'd like to use, and then select the DEWESoft export option to export the data to a .dxd file. Then you can simply delete the old data if it's taking up too much space.
