I have edited the upload.tpl file with a line where the instruction of not uploading more than 100mb file is given below the tab of upload. I added the request to either avoid the use of space in the file name words or to add "_" underscore between the words. It has helped some members who have read the instructions. Others have difficulties.
I would be very much intersted in knowing the true html/php soultion for this problem which may put off the mambers and may not be good for website promotion.
Thanks
