Understanding Disk Files File Names Each file within a subdirectory must have a unique name. The eV+ system uses this name to keep track of the file and to allow you to access the file. There are also several file extensions that are used for different types of files in the eV+ system. File Name Requirements eV+ file name requirements are similar to MS-DOS file name requirements. File names must: l Have a maximum of eight characters plus a zero- to three-character extension. l Use only letters (a - z), digits (0 - 9), and the underscore (_) character. (eV+ ignores the case of letters used in file names.) l Not contain any spaces.
l Use only one period, which marks the beginning of the file name extension. File Name Extensions You may use any valid file name for your files. However, you might want to be aware that Omron Adept uses several common naming schemes, including the following file name extensions: l V+ program/module disk files use the extension v2 . l Various calibration programs use the extension cal . l Robot specification files use the extension xml . l Omron Adept's optional AIM software uses the extensions ovr , ov2 , db , mnu , and rfd . Contents of eV+ Disk File Disk files may contain three different types of information, as illustrated in the following figure:
