Compact logging Data

Hello All

I have an application that logs pressure data for later graphing and manipulating. All this is working fine but i have one question.

At present i have the logged data writing to a text file, which when logging 8 channels upto 10,000 times a second the log file gets quite large if you log for a while.

Is there another file type you would suggest for easy writing and reading but reducing the file size and therefore reading/writing time? as at the high speeds a 200 MB file is not unheard of.

Thanks for any thoughts.

Hojo :)

If you even have it working at that speed, I don't think I'd try to compress it. It won't be as fast. What you might be able to do is to find a method to compress it after the file is written. Maybe you could create another file every so often? Like one or two minutes?

Can you show what kind of data is being logged? (just a few lines not the whole 200MB :D)
