There are hundred of application for the purpose of sharing files at android market. But the main problem they embrace is to upload files to other server. where is the problem? Your private files will be uploaded to a server that you don't know or you don't believe, and there is a possibility somebody could access to them. If the file is not so important and not valuable to be treated privately, this process hasn't got any problem. But imagine to share the file that must be secured and nor revealed to others. Anybody couldn't accept any possibility to be accessed. The best solution for this problem is to have web server on your phone. If you have web server running on your phone, you don't need to upload any files to unknown or unbelievable server. Only you check the files to be shared with selected members. That's all. The selected members will see the shared files by web browser using passcode. In this point, I think it is valuable to have web server running on my phone. Hope to know others' opinion. PS: The iFMW app for Android is to satisfy this users' need. It is based on mobile web server running on any android phone and valuable for those who care of privacy and want to control shared contents. Recommend to use it.
