Index Page
The Index page controls whether each directory's index file
is to be downloaded for a site listed in the FTP Address Book. The index file is an optional file
that FTP server administrators can place in each folder on a site to provide
descriptions for the files in that directory. If index downloading is enabled,
whenever you change directory on an FTP site Opus will look for the index file,
and download it in the background. Once the index file has been downloaded the
file display will be updated to show the file descriptions. The index is
downloaded on a background thread so you don't have to wait for it to finish
before you can access the site.
This page has two different forms. For the Default Settings entry you can configure global
settings that help Opus recognise and interpret index files. For each individual
site entry you can selectively enable index downloading.
The options that are common to both the Default Settings and
individual sites are:
- Enable index file downloading: This option causes Opus to
look for an index file whenever you change directories. Index files often have
names like INDEX, FILES.BBS and 00_INDEX.txt, but you can also configure
your own filenames to look for (see below).
- Download automatically if less than: If an index is
found, this option causes it to be downloaded automatically in the background.
You can specify an upper size limit in KB, above which the index won't be
downloaded automatically.
- If index not downloaded automatically: If an index is
found, but it wasn't automatically downloaded (because the Download
automatically option was off, or the index file was too large), this
lets you choose whether Opus should then ignore the index, or ask you (via a
dialog) if it should be downloaded.
The global options that are only available for the Default
Settings entry are:
- Match: This lets you add additional filenames that Opus
will recognise as index files. To add a filename to the list, enter it in the
field below this list and click the + button. To remove a
filename from the list, select it and click the - button. You
can use standard
wildcards for the filenames in this list.
- Ignore: This lets you configure filenames that are
exceptions to those in the Match list. You would use this if
you've specified a wildcard string but then wish to specifically except some
filenames from being identified as indexes.
- File start position: For each custom entry (i.e. not one
of the default items) in the Match list you can specify an
offset within the index file that Opus skips to before it begins parsing the
file. Normally this would be set to 0.
