How can I edit files like frontend/…/category/view.phtml?

Question

I have been trying to edit some files from the frontend folder.
On this folder I have the following folders: base, default, rwd and typologancee.

I have to create a specific filter which is going to be used on specific categories. I have thought in developing this one to append the code on category/view.phtml and products/list.phtml even though I also have thought in doing it by developing a module.

I do not know which one is the correct way but my real doubt is how to edit these files, because I have done it and the page continues showing the old code. I edited every category/view.phtml files from every frontend subfolder but there are no results.

I deleted the cache folder, reindex some data, deleted cache and cookies from chrome, as well as giving permissions to these files but nothing is happening. I would like some urgent support because I can not do any test.

**EDIT 1: I have achieved modify the file with results, but I am using visual studio code, and I did not modifying the correct file because when I find by word, some folders are being hidden when search and these folders have a diffent colour and I have not idea about why is happening this. I only have results if I modify the file under base folder, but I have read that this is a bad practice, so, what should I do? The template typologancee is active, but when I modify their files nothing happens. Thanks.

Yes you have to do modification in above files for product detail page and product detail page.and yes its a bad practices to modify base folder file what you can do is place those file with same folder structure in you current theme directory.Make sure you place file on correct location else any modification won't be visible on front-end.

You are able to see changes on frontend when u change in base file because that's how magento work it work on fallback concept which means if you already overrides the files in your custom theme with proper directory structure then magento first read that file if magento won't find file there then it goes to base folder and execute that file.

Hope this information helps.
