No you don't :
"Not Found
The requested URL /som99/Amiga manuals/ was not found on this server."
:-)
A torrent might be a better bet than a file share.
What browser are you using, I have had several downloads since I posted this from that link without problems, replace space with % and see if that helps.
You should not get that response at all but a 404 if page is not found so looks strange, ill remove the hidden tag on the folder from main page so you can see the "som99" folder from som99.se and navigate to amiga manuals.
I will check the Snort logs on my pfSense machine to see if some auto bans occured due to "(http_inspect) BARE BYTE UNICODE ENCODING" or something.
I have a dedicated machine for torrents uploading 24/7 on private retro trackers but the reason I put it on my file server (also has FTP access) is because I use the web server for more things so it's allready up and running and adding new content is quick when I want to share something for amiga.org users. I would share a lot more from my huge Amiga collection here on amiga.org if rules would allow it

Edit: Changed the sub dir to a more legacy friendly one:
Now try:
http://www.som99.se/AmigaManuals/ and report back please

Edit: Time to sleep
