[Corpora-List] language sort

[Maria Esteva]

Dear all,

I am wondering if somebody knows of a program that will recognize and 
sort large sets of files according to language. For my text mining 
project, I need to sort sets of files that contain electronic texts 
mostly in Spanish and English (although there is some French and some 
Portuguese as well).There are many free language recognition 
programmes out there but they work on a file by file bases. Let me 
know if you have some advice.

Thanks,
