Everything you are trying to do is incorrect.
1. Where did you learn that jpg corrupts files? Nonsense.
2. Your camera is sRGB, your video display is sRGB. All printers are CMYK. There is no sense in saving a picture in CMYK. XP (or any photo software) sends your sRGB file to your printer, it is translated automatically to what your printer can understand.
If you converted to .tif you will see that these files will be about 10 times the size of .jpg.
The only time you want to save in .tif is when you want to edit the file many times and "save as" many times.
We used .tif in the old days because resolution was poor and "save as" jpg many times would degrade the image. These days are gone with cameras of 2 MP and above.
If you want to convert the .tif files back to jpg you can use this free batch converter:

This used to be correct, in the days of poor resolution digital cameras and scanners. Things have changed dramatically and unless you want to print very large (by large I mean more than 12 x 18) from a pro shop there is absolutely no advantage to save tif files over jpg.
The first point is, every time you "Save as" a jpg there is a little loss and artifacts introduced, so if you edit a picture and you Save as many time, there is some degradation with each Save as, but not with Save if you use Save to save your changes as you are editing(even if you don’t do anything to the picture and you Save as just to change the name of the file, it is the Save as that is the problem). So if you plan to edit the file many times, keep it in tif until done and then save it as jpg. Since you can always saved it back as tif for further editing, no problem. The second point is, can you see the difference? Only you can tell, no amount of info will convince you. So you do the experiment yourself. It has been done many times. Here is how to do it.
Take one of your jpg file, right click on it and click on Copy. Hold the Ctrl key down and press the letter V. This will make a new file in your folder "Copy of filename.jpg (note there is no degradation when you do this, since you don’t open the file and Save as, you only copied it). Now.
1. Open this file in your photo editor and Save as. Give it the name Copy of
filename 1.jpg
2. Open Copy of filename 1.jpg, Save as and change 1 to 2.
3. Continue doing this until you Save as this file 15 times.
The first point is, every time you "Save as" a jpg there is a little loss and artifacts introduced, so if you edit a picture and you Save as many time, there is some degradation with each Save as, but not with Save if you use Save to save your changes as you are editing(even if you don’t do anything to the picture and you Save as just to change the name of the file, it is the Save as that is the problem).

1. Open this file in your photo editor and Save as. Give it the name Copy of
filename 1.jpg
2. Open Copy of filename 1.jpg, Save as and change 1 to 2.
3. Continue doing this until you Save as this file 15 times.
Then you can start opening them and look at them on your screen, when do you begin to see degradation? Can’t see it yet, keep going to 25. But the real test is not seeing on your screen, you screen magnifies everything and we don’t trust you since you know the number you are looking at.
Now, print number 1, 3, 9, 15 and 25. Print as large as your printer can print.
Don’t look at the print too closely, just place a little number in pencil on the back of them. Then, give them to somebody and ask them to place them on a table in a different order. Can you pick No.1? If you do, try again the next day. Did you get it again? If you can pick No 1 consistently, then it does make a difference. If not, no more to argue about.
Then you can ask your tif friends to pick the print they think is the best. You may be surprised!
Give us the results a few weeks from now.

Hello,
I have recently learned that jpgs corrupt files. So i opened psp6 and
went
to convert all the files that i have in to Tiffs however it had an option for RGB format or CMYK format. My questions is which one do i use, my printer (Epson Stylus Cx5400)uses cmyk color cartridges so i was thinking that is what i should use and that i could convert them to rgb if i need
to
use them for the web or anything.
Please tell me if this is the right assumption and if not what to do.
Thanks & Happy Holidays
