Preserve file name

## 💬 Questions and Help

How can I preserve the file name of the cached object?

I'm storing the file to share it posteriorly using the putFile method to save and the getFileFromCache to retrieve it but I'm losing the file name in this process. Is there any way of preserving the file name or shall I implement my putFile method?

Start by reading the putFile and getFileFromCache entry points to trace how the cached object is stored and returned. Determine whether the existing cache metadata can preserve the original file name; done means retrieving the object retains that name, with the behavior verified by an appropriate test.
