I have been using the portable free versions of Ccleaner, Speccy, Defraggler, and Recuva. The latter 2 show too many limitations...
We are about to inaugurate 2 new computers : one 32-bit and one 64-bit. - I suppose this is not a problem.
We would be interested in buying Ccleaner PLUS Professional (bundle of all 4) ; but is it PORTABLE ?
Thank you for a reply. - Pi R =
