In computer operating systems that have their main memory divided into pages, paging (sometimes called swapping) is a transfer of pages between main memory and an auxiliary store, such as hard disk drive. Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to easily use disk storage for data that does not fit into physical RAM. Paging is usually implemented as a task built into the kernel of the operating system.

WebObjects was Apple's development and runtime environment for building web applications on Mac OS X and earlier macOS systems. A .woa file belongs to that environment and stores script content used by the application.
The file is a source-code or script resource rather than a general-purpose document. Its contents are intended to work with the other files and resources that make up a WebObjects application.
WebObjects is legacy software and is no longer actively developed by Apple, so new systems may not provide native tools for working with this format.
On a Mac with WebObjects development tools installed, open the file through the relevant WebObjects project or application. Because it contains script text, a plain-text editor can also display its contents, although it may not interpret WebObjects-specific syntax.
There is no standard standalone conversion format for a WebObjects script file. To reuse it elsewhere, open the script as text and adapt its code manually to the target language or web framework.
