when uploading files to Orion Reloaded you need to make sure the file is suitably named
keep it short and simple, dont use spaces/punctuation etc
eg:
song name (remix) by john "remix" smith
this wont work
song_name_remix_by_johnsmith
will work fine
you can always give full details in the comments box, or you can name your .sfs file, zip it up, then rename the .zip
eg:
(.sfs) song 6 remix v8a by artist mr cool
zip this file, then rename it to song6remix.zip
