Nextcloud edit ignore list and refused files


I googled and looked for a solution but have not been able to find one.
The first thing is that, .mp3 files show up as ‘ignored’ on the nextcloud sync client (windows) but somehow do appear in the files when i look in the nextcloud web client. Can somebody explain?

The second thing is that .htaccess files that i use for my webdevelopment services get ignored by the nextcloud server. These files are important for me to be synced as well because it would be useless if not all my files i need to be backed up get backed up. How to fix this?

Thanks in advance!
