[SalesForce] File Upload of size more than 50 MB to Chatter Feeds through Visual Force

There are several mechanisms that allow you to upload files into SFDC. Rich Text Area is not the proper place where you should store these (I don't think its even possible either).

1. Attachments
   • Attachments are linked directly to a SOBject via the ID of the record. (Attachment.ParentId) and show as a related list at the bottom of the Detail Record.
   • Attachments are limited to 5MB of data per file.

2. Documents
   • Documents show up in Documents tab. They have a limit of 10MB. They are not directly linked to Records but can be filed in folders. -http://www.salesforce.com/us/developer/docs/api/Content/sforce_api_objects_document.htm
3. CRM Content
   • Allows large file sizes (up to 2GB). Allows for Versioning, Libraries, Metadata, etc.
   • Does not show up directly on a record layout, but you can use Visualforce to display this on a detail record with custom code to query metadata.

4. Chatter Documents
   • Allows large file sizes, versioning. Shows up in a Chatter Feed for the related record.

you can redirect like this:

<flow:interview name="CrossSell" interview="{!theInterview}" finishLocation="{!finishLocation}">
public PageReference getfinishLocation() {
    return new PageReference('/apex/some-fileuploadpage');
}

after upload, as a work around, you can start another flow instead.
