This procedure is for existing CSDS users.
Copy your existing CSDS folder (usually C:\SQDATA) to the
portable drive (say to folder P:\SQDATA).
Download the latest CAB file from http://www.ceder.net/csds/ftp/
(select file csds13104.cab). Save it on your portable drive
(in folder P:\SQDATA as above).
Right-click on the CAB file, and select 'Open'
Copy all files from the CAB file to the portable drive (in P:\SQDATA).
These files are unnecessary in P:\SQDATA, and can be deleted:
From the CSDS main menu, select 'System | Settings | Miscellaneous'.
Check the 'Run CSDS from portable drive' checkbox.
Close CSDS. This creates file P:\SQDATA\CSDS_PORTABLE.INI.
These files in P:\SQDATA can either be deleted, or moved to P:\SQDATA\definitions
These files in P:\SQDATA can either be deleted, or moved to P:\SQDATA\definitions\icon
These files in P:\SQDATA can either be deleted, or moved to P:\SQDATA\definitions\images
Delete the CAB file.
