Thank you for your help!

Once I read your comments I tried both corrections in my code, but none of
them we're sucessful.
Tim's idea kept the quotes at the moment I open the csv in Excel, quotues
appeared at the beggining and the end of the row for Excel.
Joel's idea wrote just tha variable name 'filepath' and ''filename'.
The corrections I made were:
import os, csv, time, socket
from osgeo import ogr,gdal,osr
from dbf import *

file_list = []
folders = None
for root, folders, files in os.walk( "C:\\" ):
     file_list.extend(os.path.join(root,fi) for fi in files if

ofile  = open('csv1.csv', "wb")
writer = csv.writer(open('csv2.csv', "wb"))
ruta = 'Ruta'
archivo = 'archivo'
prj = '.prj'
campos = [ruta,archivo,prj]
for row, filepath in enumerate(file_list, start=1):
    (ruta, filename) = os.path.split(filepath)
    n = os.path.splitext(filepath)
    p = n[0]+'.prj'
    filepath = ''+filepath+''
    filename = ''+filename+''
    if os.path.exists(p):
        prj_text = open(p, 'r').read()
        prjtext = ''+prj_text+''
        aRow= [ filepath, filename, 1, ]
        no_prj = 'Sin prj, no se puede determinar la proyeccion'
        aRow1= [ filepath, filename,0]
print "El archivo esta listo"
