Dear Bandrush,
I think your file does not exist as you wrote it... You need to specify also the extension. For example you should try:
IDL> print, file_test('D:/temperature.dat')
or
IDL> print, file_test('D:/temperature.txt')
or whatever extension you have.
Then if IDL writes a 1, it means that IDL found the file and it does exist. If you get a 0 it means that the file does not exist. You probably misspelled the file name or directory.
Cheers,
Helder
