I've just noticed a minor bug (presumably) in the handling of files of unregistered types. The value in the Type column for unregistered filetypes is usually the text after the final period in the filename, capitalised and with " File" appended. However, if there are several adjacent unregistered files, it seems that the Type for the first is used for the following files as illustrated in this screenshot. Also, files with no type/extension seem to use the Type of the first unregistered filetype in the lister.
When referring to 'adjacent' and 'first' above, I think that the sequence is alphabetical, not the current lister sort sequence, and applies to the (filtered if appropriate) contents of the lister rather than the contents of an underlying folder. Alphabetically non-adjacent files with unregistered extensions are displayed correctly.
Can anyone else reproduce this?
