How to change the creation date of .mp4 files in Android OS?

Question

Android

On the Bluestacks 4 android emulator, the folder contains a lot of video files (random number) with the following names: 1.mp4 2.mp4 3.mp4 ...

99999.mp4 metadata) and then change the creation date of these files so that the last file (99999.mp4) - becomes the oldest creation date, and the first file (1.mp4) - becomes the first creation date.

Or you need a tool\script (at least in android application Total Commander in manual renaming it works):
Rename these files in turn, that is, starting from the last one (999999a.mp4), then rename the penultimate one, and so on ... finish renaming on the first file (file 1.mp4)
To get the file names like this: 1a.mp4 2a.mp4 3a.mp4 ... 999999a.mp4

Using this renaming in the right order - the dates of the creation of the files will go in turn, 999999a.mp4 - will be the oldest, 1a.mp4 - will be the newest. But in this case exif- metadata I don't know how to remove.

Tell me how to implement it?

Answer 1

I do not know what tools are on the emulator. If there is no command line out of the box, then install the Termux application. Further, the question is reduced to a slightly simpler one: how to write a bash script that solves the specified task.
Hint: one loop, a touch command inside it , and no renaming needed.
