You can use data = Uncompress@Import["data.dat.gz", "String"];. Import and Export will automatically handle compressing to or uncompressing from gz if they detect that the file is gzip-compressed.

Export["data.dat.gz", Compress[AK6], "String"]. Compress gives an ASCII (i.e. 7-bit) string, so I did an additional gzip compression in Export to shave off some 10-12%. Ideally one could just Export to WDX (which I think is already compressed) but with this amount of data it is just too slow.

| Feb 12, 2012 at 14:23 | comment | added | Szabolcs | I compressed and re-uploaded the file---it was way too big at 35 MB. | |
