Hi,

you should increase the number of backslashes -- only
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
will be a single valid backslash ;-)

or may
Do[infile="U:/data/file"<>ToString[i]<>".nb";
outfile="U:/datao/file"<>ToString[i]<>".tex"; 
x=Import[infile];Export[outfile,x];,{i,0,10,1}]

Regards
   Jens
