This contains the name of the uploaded file translated into a format that can be used to save the file. The SafeFileName includes any file name extension but does not include any directory information. In general you should only use the SafeFileName for saving the file when the original name is essential to the upload. In other cases you should assign a new name to your file to allow you to maintain control over the names of files saved on your server.

Note that the fact that the file name is safe for saving does not mean that it is safe to use in a URL. For instance it may contain spaces or Unicode characters. If you need a URL safe name you should use the FileName property.

You should not use the SafeFileName property in virtual pathnames. Active Server Pages cannot resolve virtual paths containing Unicode characters into physical pathnames. If you wish to write a Unicode file into a virtual directory you should use code of the following form.

theForm.AbsolutePath = True
thePath = Server.MapPath("mydirectory\") & theForm(inName)(1).SafeFileName
theForm(inName)(1).Save thePath

The translation is done for two purposes. Firstly some platforms allow characters such as question marks and slashes to be used in the name of files. When these types of files are uploaded the file cannot be saved using these characters and they must be removed or translated into some other form.

If files containing illegal characters are uploaded from Macintosh browsers the names will be translated into the standard Services for Macintosh (SFM) Unicode format so that they can be saved intact. To a Windows user the file may appear to contain unusual characters but to a Macintosh user the name will appear as it was when uploaded.

In other cases when uploaded file names contain illegal characters these are deleted so that the file name can be used as part of a save name.
