Version tracking is extremely useful if you work with files that change very often. This is mostly interesting for coders and website owners but also for users who write large text files and artists that work with graphics or music for instance. In short; File Hamster keeps backups of all old versions of files that you specify making it incredibly easy to revert back to a previous version or take a look at the changes between different versions.

Krunch is a nice little service that offers you the option to upload and compress files in three different formats (zip, rar and gzip). After compressing the file you have the option to download it for yourself and mail it to other recipients either with a download link to the file or directly as an attachment. The service offers the option to upload and decompress a compressed file in the formats zip, rar and tar.gz. It seems to have problems with my rar files though.
