* BackupFiles used for manipulating (naming rolling/deleting) backup/version files when an alignment or project file is saved.
* User configurable options are:
* BACKUPFILES_ENABLED - boolean flag as to whether to use this mechanism or act as before, including overwriting files as saved.
- * BACKUPFILES_SUFFIX - a template to insert just before the file extension. Use '%n' to be replaced by a 0-led SUFFIX_DIGITS long integer.
+ * BACKUPFILES_SUFFIX - a template to insert after the file extension. Use '%n' to be replaced by a 0-led SUFFIX_DIGITS long integer.
* BACKUPFILES_NO_MAX - flag to turn off setting a maximum number of backup files to keep.
* BACKUPFILES_ROLL_MAX - the maximum number of backupfiles to keep for any one alignment or project file.
* BACKUPFILES_SUFFIX_DIGITS - the number of digits to insert replace %n with (e.g. BACKUPFILES_SUFFIX_DIGITS = 3 would make "001", "002", etc)
