Diana, files are, by default, placed in Directory[]. To export to a two
column text file, create a n x 2 table first.
In[1]:= lst = {4, 5, 10, 11, 3, 79};
In[3]:= Export["file.txt", Partition[lst, 2], "Table"];
In[4]:= Directory[]
Out[4]= "D:\\Documents"
Note that Parition will drop nonpairs, in this case. See documentation
for Partition for more complex cases.
