Thanks John, rtfm, I forgot to search for hidden files. I have now found the directory named with the pin number, however no files at all with ext alx.
The 8100 platform ver is 188.8.131.52 not sure if this makes any difference.
FYI I am very new to BB, I am based in Shanghai, so worse still theres no support or true outlets yet for BB's, China Mobile now supports BB's, however I am at the mercy or unqualified outfits that load/unload software on BB's, hence my urgent need to backup my apps. Recently I got the BB 8100, could not see how to connect to the internet and had no MMS support, could not see anything in the BB to support MMS, my simcard supports both internet and MMS and works fine on my samung. I had no idea how to configure MMS or Internet, no idea where you get a service book from still no idea. So I took the BB to a place, they trashed everything on the phone, but managed to load new stuff on and get MMS and Internet on.
Again thanks for you help.
