Please read this carefully, my problem is complex. I'm currently running 6 G5 Macs OSX with Photoshop CS2 on each. I deal with a ton of images (all jpegs) each day (in the 10,000 range or more). I handle mainly the color on these images, preparing them to be cropped and printed. Our network is cross platform which is creating a kink in our workflow. Photoshop is creating unknown files every time I save an image. On the Mac's you don't see them but on the PC's (WinXP Pro and Win2K boxes) hidden files appear with the normal jpegs I'm saving. They look like this...

._36430001.jpg (hidden file) size usually about 1kb to 5 kb's. 36430001.jpg (normal jpeg file) size usually about 500kb to 1MB.
These hidden files will not open in Windows AT ALL. Whether in Photoshop or any other image program. I've also tried removing the first "." just to see if it would open but no luck.

The problem with this is after I'm done with color someone else is cropping those images with an AutoCropping program in Windows. Since their are extra files with strange file names in the folders with the normal images the AutoCrop is not able to be performed. We can just delete these extra files... HOWEVER with the volume that we do it takes up alot of our time plus AutoCrop operators forget to do it. Is their anyway possible to make this file not appear. I've tried turning off ALL photoshop Image preview and thumbnails. Plus I made sure Bridge doesn't save it's cache in the folder that I'm saving too. My understanding of this is fairly advanced. But I'm somewhat new to using photoshop on the Mac's. If someone can at least tell me what these extra files are I can contact adobe about it. Thanks!

Those extra files are created because you're saving the files onto a Windows file server or perhaps you're mounting a Mac file server's share using its ability to serve it as SMB. In either case, the Mac doing the saving sees the server has having only Windows filesystem capabilities, and in that case, the Mac saves a file that has a resource fork -- which is where Photoshop creates the custom icon and/or previews -- with a file which is named the same except with a "._" on the front of the name.

If you can't get your autocropping program to ignore files with that naming pattern, just turn off custom icons and previews in Photoshops preferences and it should create that extra file.
