Where can I find the codes that have been added to my theme by previously downloaded apps?

[LSAccounting]

In order to improve the site speed, I have been advises to delete unwanted/unused apps. I have done that. Then I have read that previously downloaded apps do add some codes when being installed that do not get removed when we uninstall them. 

Where abouts in the code editor can I find these?

Hello

As you can see the code in the theme.liquid or in the cart.liquid. But you need to identify first which app you have unwanted app that you have deleted. Also you need to check which code is conflcit with the app that you are using it.

Hi,

Most of the apps added there code in theme.liquid file. You need to search related phrase and delete the code, also you need to delete the file that is added by the apps if any.

Thanks
