This is a total hack but if it's a huge file that you want to just examine the format, header, etc. and you're looking for a solution you can always just redirect the 'more' output to a new file and CTRL-C quickly. The output rows can't be controlled precisely and you will most likely kill it in the middle of a line of output but it's a cheap way of grabbing a small bit of an otherwise unusable file.
Ex.
C:\more test.csv > test.txt
^C C:\more test.txt
line 1
line 2
etc...... C:\
