Physical Location of CDE Report files (.cda, .wcdf, .cdfdf etc.)

Hello there,

Can someone please advise where exactly on the server I can locate CDE report files like .cda, .wcdf, .cdfdf etc. which I can browse using PUC "Browse Files" option. These files are saved in user home folders but I am not able to locate these home folders in Pentaho installation directory.

Appreciate your help and support.
