I post this Addon Maker for people with less of knowledge how to make a addon and for those with more

Currently supports:
File updating in CD/DVD - be aware if the file you specified doesn't exist you will be wasting precious space.
File adding to Windows dir - files with longer names than 8.3 will be renamed so if the new file name exists in CD/DVD it will be replaced.
Catalog files files - adding catalog files (.cat) svcpack method.
Other- this is more about creating inf and cab file
It might have some bugs but as far as i tested i didn't find. A lot of work was making inf file. After making addon the cab wont be made (it must be made manuallly), please check [sysoc] section and rename the key name because i don't know what to write to it so the name is the Addon Name. In the inf file you must rename in Optional Components too because the name there is the Addon Name without spaces.
Requires Microsoft .Net Framework 3.5!!! (not sure but might work with older versions too)
