Intersep or Finder Generating Empty Files

Since installing latest Quicktime and security updates on my Mac, finder has been generating empty files on a Win 2000 mac volume mounted using afp:/at/servername:*. These are not ._filename stuff. I copy hi-res photoshop files to folder watched by Intersep OPI software for low-res generation. During this process, after low-res is generated and copied to its proper folder and hi-res is moved to its destination folder, a 4k empty text file with same name as original hi-res file is sometimes generated--about 25% of the time. This only occurs on my Mac as I haven't updated rest of machines. Wave says this is a Mac OS problem and doesn't seem interested in seeking a solution.

Amiga,

These apparenly "empty" files are probably one half of the Apple-Double file system paradigm. Many Mac files contain a "resource fork" as part of the file, but some file systems cannot handle this resource fork. When these files are transferred to a file system that cannot handle the resource fork, and everything works correctly, the information contained in the resource fork is placed in a second, similarly-named, file.

This is probably what you are seeing. If you are working with images professionally, my guess would be that you will want all of the "extended attributes" that are normally contained in the resource fork to be left intact. In this case, using the HFS+ file system, and only the HFS + file system, is the way to go. Once an image has been converted to some compressed, lower resolution format such as JPG, this copy can be sent to some other file system. The originals, however, will be better off in HFS+.
