SD7 Text files with Registration?

I've tried most of the day to associate text files with Registrations. I'm not a dummy and I have read the manual several times. It doesn't tell you how. It tells how to save PDFs and Videos and I assume it works the same but it doesn't for me.
I can get it save one, but when I do another it seems overwrite the first one. Can anyone help? I'm sure I'm missing something.
Thanks!

Thanks to AJ, I now know how to do it. This operating system is SO different, I forgot what I knew before.

Let me share here for others to have access to:-

WHEN linking/associating an existing Registration to a file (text, pdf, wave, midifile, Mp3, Mp4 ... etc) on the SD7/SD40, please proceed as follows:-

* Select Registration.
* Load
* Turn off Reg
* Select Player
* TURN WHEEL TO HIGHLIGHT THE FILE YOU WANT TO LINK (do not TOUCH IT!!!)
* Press SAVE - REGIS
* File will be linked.

Thanks,

Great! I wondered if and how it could be done on my SD40.

Yes, this is much quicker than what I was going through. The step we were missing was NOT to touch the text file, just select it with the wheel. Thanks!

It already is ... same proceedure :-)

Thanks AJ

these are the quick tips we need thanx AJ
