Hello, after I've created an Illustrator file, I'll "save as" with a name such as "9927-450C.ai". Then when I view the files in the folder, I see that Illustrator placed a file named "9927-4~1.ai" (383 KB size)and also another one "9927-450C.ai" (0 kb in size). I just upgraded from Illustrator 10, which allowed me to save file names such as listed above. I'm using Windows XP. Is there a setting to correct this problem? Thanks in advance.
