Hi,
Thanks, my problem isn't really with my batch script, I've found my 
error (%%F> listin.txt and not %%F > listin.txt) but if I put a space at 
the end of each line in the filelist, I have strange error with 
gdalbuildvrt ("gdalbuildvrt does not support positive NS resolution"). 
On linux, the same thing produce an error like "file don't exist".
