AHX files are very small and you can fit several on a floppy if your PC has a floppy drive (many newer ones don't)
The addvice
Dan gives I've echoed Many times
ALLWAYS Back UP YOUR AHX FILE!!2Geckos I have 40-50 modules installed but don’t have the House codes written down
Why not some sort of backup ?
Many times files can be recovered from a system crash Unless you've already formated!(system restore Is one method)
If you can find them don't use them to upload to the interface as they probably got corrupt, but use them as a guide to build a New AHX file
As
Dan stated AHX files are located in C:Program FilesActiveHome Pro Unless you installed to a different folder!
There are many ways you can lose a working good copy of your AHX files a system crash is just one. Installing AHP updates, Plug-ins are two other popular ones.
I wish I could be of more help but looks like your going to Have to do what you don't want to do!
do not want to check each module for its House code
I have several backups one on another drive as
Dan suggested(not the best), one on another PC, one on a floppy, and (the best) one on CD along with all the installs for AHP and the plug-ins!
