File sizes and record dates are displayed in search results. The database can be categorized. The maximum file size allowed can be specified.
Autodir is a tool for creating directories transparently to the applications accessing them based on information available from sources like password and group databases. It currently supports the creation of home and group directories for LDAP, NIS, and SQL Unix accounts, and uses the autofs Linux kernel module to detect directory requests. It also supports calling backup programs when specific directories are not in use so that systems need not be taken offline for backup purposes.
I(2) Drive is an online storage solution that allows personal and corporate users to manage their important information from anywhere. It provides client and server software for accessing and sharing files through a Web interface and WebDAV clients either as a hosted service or an in-house install.
NBD-HTTP is a user-space tool that exposes a file read over HTTP as a local block device by using the network block device support in Linux kernels. Reading data from HTTP is done when needed, with read-ahead and connection reuse. One obvious use is to mount ISO images without having to download everything ahead of time.
