Irfan view does not open .ai files, but Paint Shop Pro does, so, if you have it you're done. You do NOTHING to a file when you rename it. Just change the name. You DO NOT OPEN a file to rename it. You CHANGE NOTHING when you view a graphic file (in PSP when you change anything it asks you if you want to save the changes)unless you choose to save before or when you close it.
If you are afraid you might have changed something in a file, just choose "save as" with a different name and the original file is preserved.
So you can view and rename a file in PSP (browse the folder first, and you can have all the thumbnails on display) with no risk of altering it at all. But if you're still afraid of ruinning a "perfect" file, you have to do the following: Choose any JPG file you have around and open it with PSP. 2) go to the file menu and choose "save as" 3) save it with the same or any name you like, but BEFORE saving you go to the OPTIONS button and choose a compression factor of 5 (extremely good compromise between altering the file and a huge size).YOU WON'T BE ABLE TO TELL THE DIFFERENCE. From then on, PSP will save every JPG with those settings. You can choose an even lower compression factor, if you can tolerate the resulting size...
Just remember that a JPG file, as you received it, was already degraded by the
compression. You can also save a JPG as a losseles file, like TIF (HUGE) or
PNG (not so huge, perhaps the smallest loseless format).. Actually there are
dozens of loseless formats, but you will have to deal with a huge size, do not
think they are suitable for emailing.
Remember the SAVE AS is the key for flexibility, you can save the file to your hard drive
as a TIF for backup loseless purposes, and save the same file as a low compression JPG
for almost perfect quality emailable pic, even experiment a little with PNG and so on...
By the way, you can use the zoom feature in PSP to analize and compare the original
file and the same one saved as low loss JPG or whatever you choose ... side by side.
Of course, you should use a video resolution of 1024X768 or better.
Hope this helps a little

Thanks for info. I forgot that .jpg files lose quality every time they are manipulated by a graphics program and then resaved!!
How much quality does a jpg lose with ONE size manipulation? If you keep starting with the original file and resizing and saving, isn't it only like it was manipulated and saved only once?
I receive and send art files frequently to and from different people. Some have pc's some have macs. Some have sophisticated art programs, some do not. Sometimes I need to resize (about the only thing I know how to do)a file before I send it as an attachment to someone.
Most people I send art files to usually want to receive art files as jpgs.
If I need to e-mail an art file to someone who wants it to be a better quality than a jpg, I e-mail them the original art,(ai, or eps), but sometimes I wish I could LOOK at the ai first on my pc, and CHANGE THE NAME of the file without taking a chance on doing something to slightly change the original file before sending it as an attachment, but I am unable to open ai files.
Thanks,
Gail
PS Does Irfanview, or any other non-pricey art program allow a pc user to view an ai file?
So, for sure just changing the NAME of a file does not chang the file in any way, as long as I don't open it up first? Right???
Sorry this is so wordy, I am getting a little nutty with trying to explain my confusion.
-------------------------------------------- Just copying the file to your computer isn't going to change it in anyway. Don't save it while you are viewing it in a graphics program but just copy it from the diskette to your computer with explorer. Then you can right click on it and change the name to anything you want leaving the extension the same.
I guess you are thinking about the way .jpg files lose quality every time they are manipulated by a graphics program and then resaved. Copying them to you computer and renaming does nothing to effect the quality of the file.

Sometimes I am given a diskette that contains art - either a jpg, or ai, or eps., and I would like to change the name of the art file before I email it as an attachment.
I absolutely cannot take ANY chance of changing in any minute way the virginart.
I usually send it directly from the diskette, rather than saving it to my desktop and changing the name, even if it has a name I dont want to send.
Am I crazy?
