How are audio files numbered?

Question

Video

The other day I requested and downloaded an archive of my data from Instagram (I wanted to look through old messages, but since the application, and even more so the browser, is not pulled out by the RAM and crashes after scrolling Direct for several weeks, this option disappeared immediately and there is nothing better than the data archive at the moment exist). The essence of my question is this: please tell me how the numbering of audio files occurs? The archive contains a ton of voice messages in the format "audioclip68736917873_27587169875.mp4". and initially I thought. that the chronology is determined by the quantitative value of the number in the title, but by searching for the json files of the text correspondence itself, I found that this is not the case, and the titles (the correspondence is chronological and links to audio files are ordered there) differ significantly (far from 19567328558_4789925795, but the following, for example, 19567328558_4789925796 ). find its path in the data archive -> open the audio file -> listen to the file -> repeat all the steps again. This is extremely energy-consuming, since there are more than 10,000 such voice messages. Help please, who knows how this can be done, maybe put on automation sorting based on the values ​​in the text json? Or is everything simpler and can be done manually without using code? Thank you in advance)) find its path in the data archive -> open the audio file -> listen to the file -> repeat all the steps again.
