Hi again Karishma, Since Glenn Davis provided an answer that conflicted with the one I provided, this is just to confirm that Glenn is right. I had misread your question, and interpreted "although the size is a few meg" to refer to the expected size of the data rather than the size of the files. You can indeed recover all the data (or perhaps all but the last record's worth) by using a binary editor like emacs to change the bytes that store the number of records. Sorry about the misinformation ... --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu
