where SharePoint documents are stored ?
Exactly where SharePoint stores documents? This is not going to be some thing new for the developlers/ admin’s who used SharePoint for a while, but if you are relatively new to SharePoint it might be somewhat dazzling.
Every time you hit "Save" on a Microsoft Office document and the path for the save is a SharePoint document library on a SharePoint site, the entire contents of the document is saved in binary format in a single image-type field in the SharePoint database. That's right, the entire document, up to 2 GB in size, is stuffed completely into a single field in the SQL Server database that SharePoint uses.
