public with sharing class Fileattachment1 {

    public boolean abool{set;get;}
    public boolean bbool{set;get;}
    
    public Attachment attachment {

    if (attachment == null)
    attachment = new Attachment();
    return attachment;
    }

    }
    
    
    public void check()

    public pagereference save()
    {   
    attachment.OwnerId = UserInfo.getUserId();
    attachment.ParentId = '0012800000JAVhi';
    try {
    insert attachment;
    } catch (DMLException e) {
    ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error uploading attachment'));  
    } finally {

Are you wanting the user to set the file name?

Exactly user to set the file name Brian Cherry here i need whatever the file have been attachment that name should replicate after clicking on save button Further is any feasibility is there at a time can we upload multiple files ???
Brian Cherry FWIBrian Cherry FWI
Aha, so you can simply to do this by 

    <apex:inputFile value="{!attachment.body}"  id="file" rendered="{!abool}"/> \\remove (file://\\remove) filename
<apex:inputText value="f!attachment.name}" id="whateveryouwant" rendered="{!abool}"/>

This will rename the attachment filename on your visualforce page, no extra controller required.

For multiple attachments I use this code: You'll need to adjust it for the filename input using the logic above.

Brain you have mistaken little tricky after clicking on save button one file is inserted that file name should come under choose file and also keeping a delete button then that file should be deleted
