File Management (better than Json)

Since there is now a cap on the chat GPT 4.0 memory (today) and we have to delete all those files to just have a conversation that is saved and important to us.
I use ChatGPT 4.0 for a podcast and I need those conversations for future use. Can you please give us a better way to archive or manage our files? Deleting them one at a time may be safer, but please incorporate a select feature in the left tree so that we can delete multiple files when we need too.
Thanks for considering this as an option.

I cleaned up all the archive files and anything older than 3 months, ago. Why am I still seeing this memory error. ChatGPT memory is full you can forget exsisting memory to make space. I do beleive this is an error and should be addressed. Bugs memory-issues
