Sorry -there are actually 63 folders as there are gaps in the numbering. I did not create the folders they were created by the Vienna instrument installer - I just pointed the installer at the first DVD and it did the rest for example the woodwind folders are as follows:
31 Piccolo, 32 Flute, 33 Flute II, 34 Alto flute, 35 Oboe I, 36 French Oboe, 37 English Horn I, 38 English horn II, 39 Clarinet-Eb, 40 Clarinet, 41 Bass Clarinet, 42 Bassoon, 43 Contra Bassoon, 44 FluteEnsemble, 45 OboeEnsemble, 46 ClarinetEnsemble, 47 BassoonEnsemble.
The spellings and layout were all created by the installer.
