Re: Fileupload naming schemes

Hello,
I'm just starting to work with file uploads using WOFileUpload.  Are there any in-depth tutorials on this topic, especially concerning naming schemes and security?  If there isn't any material available, then I have a couple questions to ask.
First, are there any reasons, security or otherwise, that all user-uploaded files should be renamed to some sort of safe, unique filename?  If so (which I'm guessing), what's the best way to generate the filenames?  And if not, how do you handle files of the same name?

A good method is to use a NSTimestamp().

For example,  uploads to my groupware WO app use a generated name of [groupshortname]MMDDYYYY. For more resolute naming, add the time...

[groupshortname]MMDDYYYYMMSSNSNS , etc.
