DAT to TXT

hello
i want to use the ecg file which is in DAT format but i want it to be in txt format
can anybody plz tell me how to convert it
thanks

try notepad++ editor, it can open most files.Remove the necessary the format script in your .dat file. Then force change the file type to .txt by renaming the file.I did this to data generated by Rsoft.
Hope this works.
