Well its again about google chrome, its the in thing these days mayne..
So sparyk !! you wanna change the default download location of the new light-weight but seems to be powerful browser chrome. well here you go..
1. Open Google Chrome.(that sounded common, eh ?)
2. Click the wrench icon in the upper-right corner of the toolbar and select Options.
3. Go to the Minor Tweaks tab. In the Download location section, click the Browse button and locate the desired download directory. If you want to have more control over where each file is downloaded to, check the Ask where to save each file before downloading checkbox.
That should do the trick .
