A JAR ("Java archive") file is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution. [4] JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar file extension. [5]
The practice of using manifests and checksums is fairly common practice as evidenced by their use in ZIP (file format), the Deb (file format), as well as on public FTP sites. In 2007, the California Digital Library needed to transfer several terabytes of content (largely Web archiving data) to the Library of Congress. The BagIt specification ...
VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox. Initially developed by VMware for its proprietary [ 1 ] virtual appliance products, VMDK became an open format [ 2 ] with revision 5.0 in 2011, and is one of the disk ...
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

ISO 13490 was created to allow adding more files to a writeable disc such as CD-R in multiple sessions. The ISO 13346/ECMA-167 standard was designed in conjunction to the ISO 13490 standard. This new format addresses most of the shortcomings of ISO 9660, and a subset of it evolved into the Universal Disk Format (UDF), which was adopted for DVDs ...
These files contain Enterprise JavaBeans (EJB) modules or utility classes. Each JAR file usually has its own META-INF directory with deployment descriptors specific to the JAR module. WAR Files: These files contain web modules, including servlets, JSP files, HTML files, and other web resources. Each WAR file typically has the following structure:
Increasing the size of the drive will proportionately increase the size of the bitmap, while multiplying the sector size will produce a proportionate reduction. When the operating system (OS) needs to write a file, it will scan the bitmap until it finds enough free locations to fit the file. If a 12 KiB file were stored on the example drive ...
A Maxell-branded 3-inch Compact Floppy Disk. The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. [1] Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and ...
