A friend recently handed me an old disc which should contain digitized old family photographs. The problem is, the disc was created by a photographer who scanned the photos back in 2003, and has since disappeared.

I now have the disc, and upon looking at the files, I can't work out how to open them. The CD contains a series of 100 files, no file extension aside from the 2nd file which has the extension .HIG. All files are named from 01-100. They are all mostly under 10mb, aside from a few.

I've already tried unpacking them with WinRAR, assuming they were an archive. I have also tried adding a common image type extension.

Can anyone help me work out how to read these? It's a bit of a mystery.

What OS do you have available? – Dennis Williamson Oct 12 '10 at 16:30
I'm using Windows 7. – Thunder Hips Oct 12 '10 at 16:30
Open a picture with Notepad. You should see the metadata information about which program to use to open the file. – r0ca Oct 12 '10 at 16:32
The metadata may be difficult to interpret if you're not familiar with image formats. – Velociraptors Oct 12 '10 at 16:45

You could try installing ImageMagick and see if its identify command can tell you what they are.

Excellent, thanks guys. I checked the files using notepad, as per r0ca's suggestion and from the sequence in the header (8BPS, 8BPM...) they appeared to be PSD files. ImageMagick confirmed this. I don't have photoshop but I found a free PSD viewer that works fine! – Thunder Hips Oct 12 '10 at 17:06

There are ways to do it. Follow this guide on how to open unknown file format.
