ADrive: 50GB online file storage for Free  

I've come to this website, which offers 50GB online file storage for free. The capacity is even larger than my computer harddisk.
This free plan is intended for personal use.
You can store, backup, share and edit your documents online.

The features for free account include:
- File sharing
- Folder/Directory upload (I like this feature, so that I don't need to upload the files one by one)
- File download
- Easy search tool
- Remote file transfer
- International characters support
- Zoho editor (a tool to view and edit documents)
- ADrive backup client
