We’ve been using Microsoft Sharepoint here at Plaxo to organize our projects and files. For those who have used Sharepoint, you know it’s a love/hate relationship 
Anyways, we needed to get a copy of all the files in our Sharepoint site recently. Looking around on the web, we found a few solutions, but couldn’t really find one that did exactly what we wanted. So, I wrote up a quick little app to grab all the files we needed out of Sharepoint, while preserving Sharepoint’s directory structure. It’s a command line tool and it doesn’t have any options.
It’s really not that hard; here’s the source in case you’re interested:
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using System.IO;
// replace this string with your Sharepoint content DB connection string
string DBConnString = “Server=YOURSHAREPOINTSERVER;Database=CONTENTDATABASE;Trusted_Connection=True;”;
// create a DB connection
SqlConnection con = new SqlConnection(DBConnString);
con.Open();
// the query to grab all the files.
// Note: Feel free to alter the LeafName like ‘%.extension’ arguments to suit your purpose
SqlCommand com = con.CreateCommand();
com.CommandText = “select DirName, LeafName, Content from Docs where (LeafName like ‘%.doc’ or LeafName like ‘%.xls’ or LeafName like ‘%.pdf’ or LeafName like ‘%.ppt’) and Content is not NULL”;
// execute query
SqlDataReader reader = com.ExecuteReader();
while (reader.Read())
{
// grab the file’s directory and name
string DirName = (string)reader[“DirName”];
string LeafName = (string)reader[“LeafName”];
// create directory for the file if it doesn’t yet exist
if (!Directory.Exists(DirName))
{
Directory.CreateDirectory(DirName);
Console.WriteLine(“Creating directory: “ + DirName);
}
// create a filestream to spit out the file
FileStream fs = new FileStream(DirName + “/” + LeafName, FileMode.Create, FileAccess.Write);
BinaryWriter writer = new BinaryWriter(fs);
// depending on the speed of your network, you may want to change the buffer size (it’s in bytes)
int bufferSize = 1000000;
long startIndex = 0;
long retval = 0;
byte[] outByte = new byte[bufferSize];
// grab the file out of the db one chunk (of size bufferSize) at a time
do
{
retval = reader.GetBytes(2, startIndex, outByte, 0, bufferSize);
startIndex += bufferSize;
writer.Write(outByte, 0, (int)retval);
writer.Flush();
} while (retval == bufferSize);
// finish writing the file
writer.Close();
fs.Close();
Console.WriteLine(“Finished writing file: “ + LeafName);
}
// close the DB connection and whatnots
reader.Close();
con.Close();
Here’s my VS.NET 2005 project file. If you need help with the code, please let me know.
