Select Unused/Unreferenced Audio Files
Edit > Select Unused Audio Files and Select Unreferenced Audio Files are functions that can
be used to select particular audio files that are not currently in use. Most commonly,
this function will be used when you wish to delete them, or place them in a folder
where they can be stored for possible future use.
This function looks for all song and EXS instrument files, and then checks if these songs
or EXS instruments can/cannot find their related audio files. Select Unused Audio Files
selects all audio files that are not referenced by any song or EXS instrument. Put
another way: These are “orphaned” files that have no “used by:” info when you click on
the triangular arrow alongside their names.
Select Unreferenced Audio Files is a little smarter. This function also selects the unused
audio files, but goes one step further. It also checks for songs or EXS instruments that
attempt to point to audio files with identical names. Their path reference might be
wrong, but this could be re-established by performing Functions > Find unresolved files
for selected.
Edit > Select Unreferenced Audio Files will not select unreferenced files with “suspect”
names—files of a suitable (used) name that “could” be in a song/belong to an EXS
instrument, thus protecting them from being deleted accidentally.
This type of disorganization is typically created by copying folders manually from a
sampling CD-ROM to the hard disk, via the operating system’s drag and drop facilities.
From now on, you can avoid this from happening: Whenever you want to add folders
from sampling CD-ROMs or hard disks, use Functions > Install files from… (from within
the Project Manager). This will ensure that all references are up to date.
Find Duplicates for Selected
This is a smart function that finds and selects duplicated files. The files may even have a
totally different names or file types—but will be recognized as duplicates nonetheless,
as long their length and content (audio data, comments, and so on) is identical. The
slightest difference in content means that a file won’t be regarded as a duplicate.
Delete Duplicates for Selected
The function name explains its use. The algorithm used for the detection of duplicates
is as per that mentioned above.
