Field help (ADSVOLUME) 

This "SAFE X3" volume number corresponds to the directory from where the physical files (not in the database) describing the folder objects are placed on the process server. The SAFE X3 volumes are defined in the "adxvolumes" file in the installation directory (contained in the ADXDIR environment variable). The default volume is A, but others can be defined on installing the software.

It is possible to select the volume using the key.

Please refer to the technical appendix on Volumes at the end of the Folder management documentation.
