Appendix F — Files and folders

Where iDM3 keeps everything, and what is safe to touch.

---

Install location

By default, inside your user profile — no administrator rights needed:

%USERPROFILE%\ELKO EP\iNELS BUS System\iNELS3 03.05.03 Designer & Manager for CU3-07M

The folder name still says "for CU3-07M". Historical naming — this version supports CU3-08M, CU3-09M and CU3-10M as well, and CU3-07M is obsolete. See Chapter 3.

Inside a project file

An .elp is a ZIP archive of XML files. You never need to open it this way, but it explains why .elp files compress well and why a damaged archive loses everything rather than part.

File inside	Holds
project.xml	Floors, users, gallery, version, encryption flag
projectInfo.xml	Version and structure version
config.xml	Project configuration
cuSettings.xml	Central unit settings
functions.xml	User functions — 61 of them in the default project
wires.xml	Wires
groups.xml	Groups
macros.xml	Macros
programs.xml	Time programs
system-devices.xml	Timers, counters, system bits and integers
persons.xml	People
contacts.xml	Phone numbers
DT_Notices.xml	Notices
DT_funcBlocks	Function blocks used
RT_Relations	Relations

---

Windows registry

HKCU\Software\ELKO EP\iDM3

Value	Contents
InstallDir	Install location
Version	Version and revision

Plus an uninstall entry under HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\iDM3.

---

What survives an uninstall

The uninstaller deliberately leaves:

• Projects\ — your projects

• funcBloks\ — your function block templates

• gallery\, web\, _updater\

• UserSett.hdb — your settings

Copy your projects out before deleting the folder by hand.

---

What to back up

Priority	What	Why
1	Projects\*.elp	Irreplaceable
2	funcBloks\*.fncb	Not stored in the project file
3	userDefault.elp	Your company standard
4	UserSett.hdb	Convenience

Priority 2 catches people out. A project using custom function blocks is incomplete without the templates, and they live outside the .elp. Either back the folder up, or turn on Settings → Save function blocks templates to project file.
