Some entries in index 0 are extracted as files

[villermen]

Because right now a naive check is done that only looks for the amount of entries to determine whether it is a file or a collection of entries. Files with one entry are considered a single file.

• Try to find a common link between a indexes that contains entry files and indexes that don't.
• Base file type on index?

They can't be decoded as entry files, so maybe Jagex also uses the simple logic (for once) of multiple entries -> entryfile.
