How long is file_id api telegram stored?

Question

API

How long will the id of the file I sent to the bot be stored on the telegram servers? For some reason I don't see this in the documentation.

Answer 1

Found the answer myself, sorry. Here is the answer itself, you never know who will need it:
the file_id of the files sent by your bot will be deleted after sending several thousand files.
For accepted files, file_id can be considered eternal and unchanging.
