Krun.ch is an online tool that allows you to compress, store and send files online. Krun.ch is unique in that it is only a temporary storage solution as files expire after 24 hours. Prior to expiration a user can send files around as they see fit not to mention users will be able to keep track of your krunched and unkrunched files and easily access.
Krun.ch is the latest creation of the young and talented developer Kailash Nadh who also created the popular ping engine Pingoat and splog search engine SplogSpot before selling them both in March 2006. I find that all of Kailash projects are simple to use which is a characteristic I thoroughly appreciate in his work. While I understand there are a number of similar services like DropSend (highlighted previously) and Whale Mail among others I would recommend giving Krun.ch a whirl.
