Attachments in subfolders


New member

I would like to ask how attachments are organised by XF.
I was recently contacted by my hosting provider that having of too many files(currently 15000 approx) in single folder phpBB/files/ is not a good programming practice and by time it may cause slowing down of server, backing up process, etc. ... better would be to have files in subfolders by 1000 files approx.

How does it work in XF ? Attachments in single forum or are they organised in subfolders ?

Thanks in advance.
