File Preview

[RAFACN]

Good morning!
Do somone have a script for previewing doc/txt/ppt/xls/similar files? I am going to add to one of my programs a kind of file manager that using a specific variable(ID) is going to create a folder with its name by the first time i call an "add file" and remove that folder when removing the last file, but i would like to know if its possible to preview these kind of documents i'm going to add. Could someone help pointing on the right direction for me to search?

Thank you!

Sorry my english!
