1.3 Repository Files

The repository files are generally arranged in a single directory hierarchy. The highest-level directory contains one file artbase.roo that contains the names and paths of all the repositories, and a subdirectory containing each of these repositories. Initially there is probably only one repository, but later you may make backup or checkpoint repositories, copies of your main repository made at a certain time.

In a repository directory there are two files, manager.ab and trid. The manager.ab file contains the names and paths of all the areas in that repository, the names and encoded passwords of all the users in that repository and any disk name mappings needed to access the repository. The repository directory also contains several subdirectories:

areas	Contains a directory for each physical area in the repository
users	Contains a directory for each user in this repository
backup	Contains a copy of the repository from the last successfully committed transaction
comm	Only created when a multi-user repository is used. Contains information about multi-user access using file communication.
counters	Only created when a multi-user repository is used. Normally empty.

Please note that the repository directory is an undividable whole and must be treated as such. This means that the repository folder and its content must be kept intact through the possible file system level operations. So make sure to always copy the whole directory and never edit, remove or replace subdirectories or files within.
