This year we migrated from OS 9.2 to OSX 10.4.6 and have had substancial difficulty with our image files. Anything that had .eps, .tif, .jpg, (etc) hidden when the file was saved will not open in photoshop on OS X unless the extension is physically added to the file name.

I know everyone is going to say that they should open, but they don't. So let me tell what I think caused this problem.

Our file naming convention was part number (414-454) + image sequence (.01), (.02) so the image name when saved on OS 9.2 became 414-454.01 or 414-454.02 The new macs recognize the above files as UNIX EXECUTABLE FILES.

Unless the extension is actually added to the file name photoshop won't open them. Not a big deal we can type an extension on each individual image, but there's over 20k images and we don't know which are TIFs, JPGs, EPS, etc... unless we try and fail and try again. It's a pain.

Why do the new macs not understand what kind of files they were?

Also, the image previews were lost somehow, if you open up our old quark pages update the images and your images change to a grey box where the image was and file name. Poscript EPS picture ...

Baffled and Frustrated

canadahat,

welcome to webmasterworld!

I think the problem you are having here is that system X being unix based is looking at 414-454.01 and thinking "what the heck app is .01?"

This might work, single click on 414-454.01 and ask for its info (command-i), in the window that pops up, look for Open with: choose Photoshop and then click on the "Change All.." button. This will have the effect of making anything ending in .01 open in Photoshop.

Be careful using this, as anything on your computer that ends in .01 will now open in Photoshop.

Repeat as above with all others (.02, .03 etc)

Hi thanks for the response - we've tried that actually. Photoshop won't open the image unless we add the extension (whatever it was) and if the incorrect extension is chosen, then photoshop complains and won't open it. There lies our biggest problem is we don't know what they were anymore unless we make several attempts at changing the file name until we succeed

I think you're right about it being a unix based issue - I was hoping to dig around for perhaps some apple script or command line help in extracting the file type from the data fork (or where ever the information is now about the file type). It must be somewhere because if you change the extension to Tiff, and it's actually and EPS photoshop seems to know and gives us lip! so we want to somehow extract that info out of the file and programatically re-name everything.

Do you have GoLive? (this may work in Dreamweaver, not sure)

Create a site in GoLive, then click on each image, in the Inspector, you can see what type (jpg, gif etc) and what program created it...

You can flag all of the jpegs with one color and all of the gifs with a different one in the Inspector, then you can sort them out in the Finder by color...

I would say to give GraphicConverter from Lemkesoft a try. It will open almost anything...you will probably have to play around with it to maybe do a script for the specific files, but I think "you can get there from here" with GC.

Added: If you have files with a "/" in the filename, be careful. I am also dealing with a 9 to 10.4 system and Quark clobbers the file!

I'm not sure (don't have 10.4), but I think the Spotlight search utility should be able to identify file types correctly.

If you open the file(s) in a text editor there will be a file-type indication on or very near the first line of the gobbledygook:

JPEG = JFIF
GIF = GIF89
TIFF = TIF
PSD = 8BPS
Photoshop EPS = 8BIM
PNG = PNG

The previews are often in TIFF, however the application must be able to "dig into" the file to grab the preview.

Pre-OSX Macs didn't care about the file extension and just read the file header to determine its type. Now with the Unix base, file extensions are kind of important in that if they are present then most apps will default to using the extension to determine the file type, as you're noticing.

Maybe you could put together a little script that opens each file as text, looks for a little pattern as above within the first 100 characters and then closes the file and adds the appropriate extension? 20k are a lot of files to touch ... have fun! ;)

the go-live trick didn't work - again - most of the images we have are print-ready and moved to the website after conversion from a web droplet script... the photoshop can't open the files, so it's sort of a missing link in the process...

I will give the text editing idea a shot. Downloading BBEDIT right now.

When you say Photoshop "can't" open the files, do you mean Photoshop doesn't open the files when you double-click on them in the Finder, or do you mean they don't open even when you drag the file onto Photoshop's icon?

Often files will open in the app when you drag them onto the icon even if the file associations are messed up and you can't open them by double-clicking. I can't tell from your previous messages if you've tried the "drag onto icon" method.

FWIW, Apple Preview can open up JPEG's I've renamed with a .1 extension, and then choosing Tools...Get Info (or apple-I) displays the image file type.
