news:

The search file/word of XP works only with this extensions file (I try

this

but there are certainly other extensions):
.asa .asp .bat .cmd .css .dic .htm .inf .ini .js .log .txt .vbs .wri .xml
.xsl.

I want search a word in file with extension: .CTL and .SQL.
How can I do it with search of XP?
Thanks
