I just found in another topic that the filenames of downloaded files were some random array of characters. (topic with uploaded files here)
Is that a bug?
Testing below to see if it happens here as well|:
indeed the above file is stored on the server as : /uploads/default/original/3X/d/a/da39a3ee5e6b4b0d3255bfef95601890afd80709.TXT
