Hi,
You should add your OS and AC version in your signature so we know how to help. If you're doing a reformat, you're probably on Windows
😉
Note that you should avoid moving AC9 to Vista unless you want troubles...
This info is from the ArchicadWiki:
---------------------------------------
On a MAC
- * /Users/<user>/Library/Preferences/Graphisoft/AC xx.0.0 yyy v1
This folder contains the basic preferences files and all the Work Environment files
- * /Users/<username>/Library/Preferences/com.Graphisoft.AC xx.0.0 yyy v1.plist where xx stands for the version number of ArchiCAD, yyy is the localization of ArchiCAD
This file contains some basic settings of ArchiCAD. The Windows equivalent of this file are the Registry keys
- * /Users/<username>/Library/Caches/Graphisoft
This folder contains library cache files and the local cache copy of network libraries
- * /Users/<username>/Library/Application Support/Graphisoft
This folder contains the Archicad autosave folder, the ArchiCAD templates, the DXF-DWG translators, IFC preferences, Bug reporter log files, publisher log files.
Note: You will want to back up this folder in order to keep your Work Environment files and DXF-DWG translators
On a PC (Windows XP)
- * Documents and Settings\<Username>\Application Data\Graphisoft\
This folder contains the basic preferences files and all the Work Environment files
- * Documents and Settings\<Username>\Local Settings\Application Data\Graphisoft\
This folder contains library cache files and the local cache copy of network libraries, and IFC settings
- * Documents and Settings\<Username>\Graphisoft
This folder contains ArchiCAD templates, crash logs, publisher log files
---------------------------------------
Hope this helps.
