Cut Contours
I am trying to cut a small region of a lidar contour string because the lidar covers a huge area and when I try to create a DTM Surface it takes forever to create and freeze up my laptop.

The easiest way is to filter it. You should be able to simply apply a filter with North greater than 888888 AND North less than 9999999 AND East greater than 88888 AND East Less than 99999 which will filter the strings to a small area. Eg
Make sure the filter covers the area you want and then right click on the name and select Edit -
when the file opens up select File -> Save As and the file will be saved as the filtered subset that you can use to create the DTM.
Hope this Helps

I did try both options and Ron you are right the Clipping took up much memory and PC frozed.
I take both suggestions and will use depending on which PC I use.
Much appreciated, I managed to cut my strings.

Then limit the creation of the contour lines to a bounding box.
You assistance is greatly appreciated.
