 File Storage 

The module files and description files are stored in the file system of the OS.

The files required to create a program can be stored at different locations in a file system, in different file systems, and on different computers.

The potential paths are specified in the $VMAKE_PATH environment variable. This variable must be adapted accordingly to be able to access older file versions.

There is a separate directory for description files, and a separate directory for module files.

Each of these directories has at least one subdirectory that reflects the logical hierarchy of the files. Files are only stored at the lowest directory level.

The files can also be stored in a database. As a rule, however, databases do not provide adequate support for search operations, with the result that the files cannot be accessed efficiently.
