Lost folders –

Here is the text of a chat I had with "Milan" at tech support.  The solution he proposed did not work. His response to my question is in parentheses and bolded.  ( Milan:  Okay, on the bottom right of that pop-up window, please make sure that "all files" is selected.) I am having two problems:  I cannot upload certain files to outlook emials when using explorer. When I open "documents" I used to have a folder called "my documents" available. When I opened it there were a number of sub-folders I could access to input as file attachments.  I can no longer do that.  I could always do it with hotmail.  Also, outlook is not putting emails into an established subfolder that is on my list.  Here's the wierd part 1. on Mozilla firefox it loads the mail into the subfolder it should, but on firefox I cannot download the attahcments.  So - I cannot find files I should be able to find on Outlook when using IE. I can upload files to outlook email when using Firebox.  Also, IE is not sending files to a specirfied folder, but it does send them to that folder in firefox.  What is going on?
