Metadata
These options define what happens when Opus saves certain metadata to files
(via the Metadata Pane or
the Edit Metadata
command).
- Write APE tags: When writing metadata to MP3 files, Opus
will save tags in APE format as well as ID3v2.
- Write ID3v1 tags: When writing metadata to MP3 files,
Opus will save an ID3v1 tag as well as ID3v2.
- Apply changes automatically in the metadata panel: When
this is turned on, any changes you make to the metadata of a file via the
panel will be saved automatically when a new file is selected or the panel is
closed.
- Update last modified file dates when setting metadata inside
files: Normally the modification date of a file is unchanged
when Opus saves metadata - if this option is on, the timestamp will
be set to the current time. This option deals with metadata changes which
are written into the files themselves, where the file format has inherent
support for it, such as ID3 tags in MP3 files and EXIF tags in JPG files.
- Update last modified file dates when setting metadata in NTFS
ADS: If this option is on, file timestamps will be set to the current
time when metadata changes are saved into NTFS ADS (alternate data streams).
With this option on, a file's date will change if you place or modify a label
on it (if labels are stored in the filesystem rather than a central
configuration file). Changes to file descriptions, ratings, and the general
"tags" field will also bump a file's date, for file formats where Opus does
not have a way to store them in the main file itself (e.g. text files). You
would normally want this option off unless you are using a backup tool which
preserves NTFS ADS and uses the modified timestamp to decide what to back-up.
