Hi,

Invalid for what? Whether this can be accepted by a program as a 
filename depends on the OS and filesystem you are using. In most cases 
you are asking for trouble using all these special characters in 
filenames (especially / is a bad choice on most Unix systems, among them 
OSX and * is also a nice candidate for funny side effects on almost 
every OS I have worked with). Even if you find an OS/FS/program 
combination that accepts what you want you might get problems whenever 
there is the need to handle these files with something else, and 
something else could be the backup software of your choice, the anti 
virus program your boss wants you to install, a file archiver program or 
your email client...

> Is there any type of utility I can use to name files this way?  The ideal solution would be to name like the above and then have the  File/Open menu display all the file names and directories in Standard Form.  I'm not familiar with WorkBench.  Would that help?

I doubt that there is a utility which would achieve this. I'm not sure 
because I haven't tried it, but I think this is so out of scope of 
workbenchs purpose that I don't even bother to try...

I have no idea what you want to achieve, but for the above reasons I 
would strongly suggest to find other ways to do what you want. If you 
would tell us what that is, you might get tips on how to achieve it...

hth,

albert
