... Copy old Chains files to Macros, once only per session, never overwriting. Leave old files in place in case the user downgrades their Audacity. When removing a Macro, remove also any like-named legacy chain.

\class FileNames

\brief Provides Static functions to yield filenames.
|
|
|
|
This class helps us with setting a base path, and makes it easier
|
|
for us to keep track of the different kinds of files we read and write
|
|
from.
|
|
|
|
JKC: In time I plan to add all file names and file extensions
|
|
used throughout Audacity into this one place.
