The value of this operator adds the extension .data to all filenames referenced when 
using PostScript emulation file operators. To prevent the .data extension from being 
added, issue the following PostScript emulation command:

statusdict begin

false setfilenameextend

end

To add the .data extension automatically again, issue:

statusdict begin

true setfilenameextend

end

The following example shows how to remove a file for the font myfont from the disk. 
The PostScript emulation resource collection filename is

. The 

PostScript emulation command to remove the file is:

statusdict begin

false setfilenameextend

(%disk%myfont.type1) deletefile

true setfilenameextend

end

For other file types, see page 6-6.

We recommend that you enable setfilenameextend as soon as possible 
after you disable it. For example, the following PostScript emulation 
commands generate an undefinedfilename error:

(%disk%iconimage) (w) file dup

(0f0606060686c6ff) writestring closefile

statusdict begin

false setfilenameextend

end

(%disk%iconimage) (r) file

%%[ Error: undefinedfilename; OffendingCommand: file ]%%

This occurs because the filename actually written to disk is iconimage.data. When 
setfilenameextend is enabled (the default), all PostScript emulation file operators 
treat filename operands as filename.data; when disabled, they treat filename 
operands literally.

If you receive unexpected undefinedfilename or similar errors, try toggling           
setfilenameextend and sending your print job again.
