Indeed, getting the blob is rather easy but handling decompression will be trickier and this specially since we may encounter different formats : MSZIP, LZX, etc ... If I may help, which langage are you using for GWT? (I am a delphi/FPC dev).

Thanks Dencorso, i have been reading/following this forum for years : great place ! Was about time I contribute

Hi Gents, The MS CAB specifications are detailed here : https://msdn.microsoft.com/en-us/library/bb267310.aspx#cfheader . Parsing headers (cfheader, cffolder, cffile, ...) and downloading only the compressed blob of a file looks achievable thus avoiding to have to download the whole CAB. Regards, Erwan
