Comparision of two huge unix files - Reconcilation

Hi,

I have two huge file; each one has approximately 150000 lines. I need to compare both of them and store the unmatched lines into a different file.

I have searched for everything in google but did not get solution.

Files are:
File1
Code:
NRALBAMINDB20003726
NRALBAMINDB20003727
NRALBAMINDB20003728

File2
Code:
NRALBAMINDB20003726
NRALBAMINDB20003727
NRALBAMINDB20003733

Output:
Code:
NRALBAMINDB20003728

I have tried the below query -
Code:
awk 'FILENAME=="File2" {arr[$0]++}
FILENAME=="File1" {If ($0 in arr) {continue}
else {print $0}}' File2 File1 >File3.txt

But its not working, output I am getting is - complete file1 gets pasted in File3 that is 'if part' is not getting executed.

One more thing, If i try the code with pretty less no of entries in File1 and File2 say 20 entries each, it works.

Thanks,
Suman.
