If all file hosting sites (like filesonic) are close, will hosting industry be affected?
File hosting is not going to die anytime soon. All that's dying is the ability to profit from knowingly hosting copyrighted files, and/or sharing such files.
That may be true but that is also the main source of revenue for these file hosting sites.
Does this affect you?
It will affect almost every website that operates within the EU. This is not restricted to EU-only domains such as .fr, .uk and .de but any website that operates in the EU. Even if your website is based in the US, on a .com domain, but offers services to people in Europe your website must comply with this law.
I can think of a few other file hosting services.
* Google Drive
* DropBox
* BoxNet
Just to name a few.
Otherwise you can simply look for a webhost that wuits your file hosting needs.
