Shortening Binary Files

[lord_dude]

How do you chop the end off a binary file (eg make a 100 bytes file 90 bytes)? The only way i can think of is to write the file out again - the part you want to get rid of but this would be very slow and i am sure there must be an easier way i hav't thought of?

Sorry, thats the only way it can be done

it doesn't have to be slow.
if it is a small file, and you have it stored in a string buffer, then "open filename as #1 for output"
print #1, left$(buffer$, 90)
