How can I change my pictures' and videos' date on my phone by their filenames?

Yesterday, I moved a bunch of old pictures and videos to my phone, using a FTP server I installed on my phone. Everything went fine, but today I discovered that the date of all the copied photos and videos was set to yesterday. As a result, my photos and videos are now showing up in the wrong order in the Gallery app. (Click image to enlarge) " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Luckily, the date and time is still preserved in the filenames. Right now, I want to restore the photos' and videos' date using their filenames. I'm interested in a way to do so. I don't really care whether it's by using an app or script or something else. I'm aware of the fact that I can copy the files from my computer to the phone again using a different protocol, but that is not what I'm looking for.
