Move media files to monthly and yearly folder

First of all, hello.

On my WordPress site, it used to upload media files into the /uploads folder until now. But it started to load slowly because there were too many files. Also, when I want to access a file in a folder, even the browser has difficulty opening it.

For this reason, I selected the option “Keep media files in monthly and annual folders” in the media settings section. But the files I have uploaded so far have not been automatically moved to the monthly and yearly folders. I think it is only valid for the files I uploaded after I made this setting.

So how can I move the files I’ve uploaded so far? I don’t want to lose title and alt text information. Also, so that the pictures in my articles can be opened in full screen, I add a link to open the media file when I click the picture. Do I have to manually correct the links of the chiefs in all my posts after the pictures are moved?

Please answer each of my questions. Thank you. Healthy and happy days.
