You could output over it with blank spaces, if that''d suit your program..not sure about deleting.

I guess, but it''d be good to be able to delete the line too.

There are no spoon... and there are no lines in files, there are only characters. You must interpret a bunch of characters as a line yourself.

Pseudocode:
for each line in original file that shouldn't be deleted:
output line to another file
delete original file
rename other file to the original file

i ended up just reading each line into an array and then deleted the thing i wanted from the array and then rewrote all the contents... but will this mess up other things trying to access the file or will it be too quick to ever notice?

It depends on the size of the file and it depends on the sharing enabled for the file. The way you deleted the line is one way to delete part of a file.
