Thank you Why in several subfolders (i.e. C, G, L, M, S, W)? > easier to maintain, easier to edit for YOU, the user Why not all together? > MANY identical filenames => impossible In your particular case: you've put the 'DP' folder under the 'sysprep\D' folder, why not put the drivers straight into that 'D' folder, or maybe even just a 'D' folder and no longer 'sysprep\D\DP'! (confusing sentence, I know )
