[Good practice] Files should not be located in directory paths with more than 6 higher level folders [Rationale] 
There is an accessibility trade off between the width and depth of directory structures. Best practice is to keep to between 3 - 5 levels.When files are transferred to portable media, burning software such as Nero Â© is unable to replicate directory structures of more than 6 folders. File and folder names will be shortened by the software and this can lead to naming corruption.
