Previously uploaded file on bolt is still showing despite uploading new file on bolt

I had previously uploaded a file on bolt . I am now trying to upload a new file on the bolt. It shows file uploaded successfully but when I open that page it shows the same output of the previous file which I uploaded.What should I do

Hi @sciencehead05 ,
Your file name should be index.htm .
Let me know in case you need further assistance.

Thanks it worked:)
Can you tell me how to connect an infrared sensor to bolt using a bread board?
