How to download some file from visual force page

I have the following task 

I have several links on page from which some files must be downloaded
 Presently I don't know  what exactly format it will be. So let's assume it can be anything(.img, .exe, .txt. etc)

So I need to know approaches how to provide downloading all the formats
Can someone please provide me with such  API references or documentation to accomplish that aim

    <apex:pageBlock >
        <apex:pageblockTable value="{!TestObject__c}" var="v" border="1"
                                     columnsWidth="100px,200px,150px" cellspacing="0" cellpadding="8">
