Probably ancient to most, but still pertinent to me.
I used Photoshop (on the mac) WAY back in the day. Can't remember the version, but back then, Macs had resource forks, finder.dat and stuff like that. I have a file that was amazingly 8mb in size (gigantic back then) - it had layers! And yes, I still have the resource fork files and so on.
Still, I cannot figure out how to open it.
I have other files from that era - photoshop says it does not recognize them, but irfanview (god bless it) opens the simple ones. But it has a header error with this one.
Any idea on how to open ancient files like this? Any resources? I googled, of course, and the standard answer is "photoshop opens all psd files from any version" - well, this is before the mac put "psd" on these files.
P.S. I was able to open it only a few years ago. 5? 7? Time flies, doesn't it. Yes, should have resaved it in a newer format. I know.
Hmm, from what I read, back in the day, how ever long ago that was, Mac's opened files according to the header file for determining the file format. From what I gather new Mac's support file extensions and maybe file headers as well.
So, going by that and knowing that windows psd files have both a header and the file extension and uses only the file extension, my guess is mac can do the same. Try creating a copy of the file and add the .psd extension to the end of the filename. If it works, it works. If not, at least you tried something.
Good thought - I did try copying the resource fork folder and the file to a mac, but didn't rename the file to a .psd, thinking the resource fork file would handle that. I'll give it another try. I DID rename the file to .psd on a windows machine but that did no good. Were there other .xxx extensions back then it might have been?
I tried opening the files as text, but didn't see anything obvious to help in this search to open older files.
If the file is a layered file from photoshop, then it would have to be a psd (photoshop) file as versions before 6 wouldn't save layered files
in anything but the psd (photoshop) format.
On a windows machine if your adding the file extension or using File>OpenAs>PSD that should work on a good photoshop (psd) file, even one from photoshop 3 on an vintage mac, but
since infraview can't even open it, it may well be the file has been corrupted somehow.
On a later mac you should be able to use File>Open, highlight the file in the open dialog and then choose psd.
