View Full Version : weird file formats... help!

I'm looking for vintage botanical illustrations (yes, my job is a thrill) and stumbled across a great resource with tons of downloadable stuff. the problem is that all the illustrations are in .CAL format. none of my Adobe apps will open it. it's driving me nuts. does anyone know what the hell a .CAL file is? how should i go about opening them?
help me out please. i'll love you forever and ever!

Adobe Photoshop should be able to open it. Maybe they were created with a Photoshop newer than yours? I could try to open one of them to see what happens.

i have CS3, so i don't think so...

it'd be great if you could try opening one of them... here's the link:

click on the "illustrations of plants" folder... the files are all there.

http://filext.com/ is a site where you can see what file extetions are for.


And of course there's several options.

No I can't open it either, I've tried several programs.

I found a program that can open it though, but I'm not sure if it's a legit/safe program. It's called ThumbsPlus (http://www.cerious.com/download.shtml).

But there must be a pluging for Photoshop somewhere, right?

it's PC only... dammit!

i can't find a photoshop plugin... but apparently Paint Shop Pro can open it. except... it's a PC only program too!

I can try opening and converting them into another file format for you, once i have access to mah cousin's internet.

i'd like to point out that this is a prime example of why we should all support open file formats.

QFT - its ridiculous that .cal is supposed to be opened by photoshop but cs3 says it doesn't recognize it

I have it, but i never cared to install it.

Q: do you need the illustrations inside the pdf files, or the separate ones inside the folder?
I'm exporting the pdf files as JEPG just in case.
