Dear frJericho ,
RTE8's file provider is changed for supporting the multiple storage .
And file url is joined at client side , by 3 parts :
1 - public override string GetUrlPrefix(Storage zone) of the custom EditorFileProvider
for example , "/uploads" , "/download.ashx?file="
2 - public override string GetUrlPath(FolderID folderid) of the custom EditorFileProvider
for example , "/" , "/subfolder/"
3 - PathItem.Name
for example "hello.jpg"
so the full url is /download.ashx?file=/subfolder/hello.jpg
If you implement something like download.ashx for it , it need to parse the /subfolder/hello.jpg , and find the real file data to download.
Regards,
Terry
