ASP/VBScript File Upload
How can I upload files using JUST vbscript and asp?

I trawled the web for ages looking for a simple free pure asp / vbscript file upload.
I finally found one that I modified a little to check if a file already exists in the specified upload directory, and if so donÆt perform the upload.
The original upload was by Jacob Gilley and can be found at http://www.asp101.com/articles/jacob/scriptupload.asp
The file upload consists of 3 active server pages (asp):
1) The form-send asp to post the intended upload file.
2) The receiving asp to process and save the intended upload file.
3) The functions asp which is included in the 2nd asp and contains the functions used to aid the upload (This file does not need to be edited whatsoever).
Please note û You must have VBScript 5 or above installed on your server for this to work!
Finally, many thanks to Jon Hawkins for his help in pointing me in the right direction!!
