How to post a file on the Internet?

Question

Computer networks

I wrote my program. I don't have my own server. But the program must have access to one file. It must be placed so that the program can download it at any time. But at the same time, I must have access to it and edit it at any time. The file format is json or txt. The size is less than 1 mb. The file cannot be edited by other people. In short - I need to place a file in the format somedomen.com/files/myfile.txt
The program should download it to the PC every time it starts. How to implement it?

Answer 3

Some programs, for example, password managers, have their databases in the clouds (Dropbox, GDrive). Those. you can place the file in a free cloud (you can even have two, for reliability), and access it. Yes, you have to figure out how to do it.
Of the pluses - the file can be synchronized on a PC, its changes will be immediately visible, and vice versa, changes on a PC will immediately fly to the cloud. It can be convenient for debugging and, depending on the tasks, operation.
