Name and ext of uploaded files reference to random name made by phpbb upload system

[Bymemor]

When you upload files via phpbb to aws s3 bucket, it turns out that files are stored with randoms name which are created by phpbb upload system.

When you disable this extension and upload files to phpbb forum although they are stored with random names when users download these files they see real names of them.

But when files that stored in amazon s3 bucket are downloaded users see only random names and I think it is confusing problem.

And one more issue related to this problem. When me and users download files as docx, pptx from PC, it can identify and open it . When it comes to smart phones they can't identify and so can't find proper program to open them. This problem really confused me and I don't understand how pc can, smart phones can't identify. But I think the main reason of problem is the name of files. Because in their random names they don't have extension such as .docx, .pptx or . xlsx, so I believe that's why smart phones can't open.

I hope these problems will be solved.
