thanks for helping newbies like me with your competent answers: I have a question regarding redirects from URls with parameters to new URls without parameters, probably using the .htaccess file. 
I have tried answers on questions like this
[htacces to redirect without params](https://stackoverflow.com/questions/5589335/htacces-to-redirect-without-params)
[301 Redirect of old url with parameters to a path without parametes](https://stackoverflow.com/questions/7277154/301-redirect-of-old-url-with-parameters-to-a-path-without-parametes)

but I'm still unsure how to proceed correctly.

So here is my problem: the old URL structure
<http://www.mysite.com/my-files/query-qry?origen=1&destino=&aerolinea=DE&proveedor=barceloviajes&clase=F&escalas=>

should redirect to this one: 
<http://www.mysite.com/my-files/query-qry>

to put it short: I want to add a 301 redirection without all parameters. What is the best and fastest solution and is there a rule that can be applied?

Thank you very much for your help!
