ParseRaider:
Hello,
I was advised to change the name of my store to something other than zen-cart... I used /zen-cart6/
By whom? and Why?
Also, it is a little unclear from the above as to exactly what it is you are needing/wanting to change. The folder name and the store name are totally different and unrelated.
ParseRaider:
Then I will hopefully rename the zencart folder to new name /Pickle_Jar_101/
Ahah, so it is the folder name you wish to rename - again, why? If your configurations have been performed correctly no one will ever see the name of your zencart folder - and it really wouldn't matter if they did, because lets face it - you are running a store designed for public access - so this folder, and most folders underneath it actually need to be publically accessible. There is no point or purpose in trying to hide it.
The /admin/ folder is a different story of course - you don't want the public to access this folder, and ZenCart forces it to be remained and the guise of 'security' (although almost everyone with a clue knows that 'security by obscurity' isn't too much of a hinderance). It does stop many 'script kiddies' from hogging server resources though, so its not a bad thing.
Again, this doesn't apply to the store folder itself though, that needs to be publically accessible - and therefore easy for people to find/identify no matter what you decide to call it.
ParseRaider:
What else would I have to change to make this a smooth transition?
Seriously, if the store is currently working and is residing in a folder called /zencart/ just leave it.
Hmmm... just had a thought though, if the URL for your store is something like https://www.mydomain.com/zencart/ and your plan is to change it to https://www.mydomain.com/zen-cart6/ or ultimately https://www.mydomain.com/Pickle_Jar_101/ I again have to ask/wonder why? Isn't this just going to make user UNfriendly URL's (I've never heard of anyone wanting that before) ;-)
If this IS the format of your store URL then your best option would be to change the 'document root' (as well as the two zencart config file) so that it is accessible @ https://www.mydomain.com/ (no folder path name needed).
You can also achieve the same thing by moving all your files out of /public_html/zen-cart/ and placing them directly into the /public_html/ folder (which is probably your current 'document root'. Again, you'll need to edit the 2 zencart config files to reflect this change.
As I stated at the outset though, with the little information you have given it is a little unclear as to what it is you are wanting to do, and why.
Cheers
