Upgrade and overide system question...

[joyjoy]

One more question...what about defaults that come with zen-cart. Shipping/payment options, music, genre, records, etc. These would be files that I would never have the use for.

In an effort to keep my files under control size wise, can I remove these files or will they impact my site?

Should my mods be placed in an override folder as well?

Yes and mos well constructed modules have folders named "my_template" that you must rename to your template name

Also, do I do the overrides system for any and all changes that I have made to core files? i.e. email, classes, defines, etc?

Remember the RULE??

/classes has no "classic" folder - - most do not touch those files but if you do I suggest you adopt placing some word or phrase in the commented head of the file
I enter *kobra

That way, when an upgrade is in order these files that can not be overridden can all be located using the dev tool kit and searching for "kobra" & now I have a list of the files I have touched in addition to those that are in overrides folders

These would be files that I would never have the use for.

In an effort to keep my files under control size wise, can I remove these files or will they impact my site?

I would not - - The complete default files set is only about 20K so there is little economy in this area

Okay, thank you for the clear explanation.
