Unable to download big size file using DUA

[Jim]

I am trying to use DUA to download update files to my XPE devices. I
had no problem when the size of update files were less than 10M, but
once I tried to download a big size file (90 - 120 M), the HTTPGET
command failed. Dose anyone have any idea about this issue? Is there
any limitation for DUA on the size of download files? Thanks for replay

I kind of figured out what's happening on my XPe thin client. My system
drive C:\ has about 40M free space, and I have another USB drive D:\. I
tried to download files to D drive. But even I changed the WorkingDir
of DUA to D:\dua, the HTTPGET seemed to buffer the whole download file
on C: first, then wrote to D:. So whenever the size of download file
exceeded the free space of C:\, the HTTPGet turned to fail. Is there
any way to avoid this issue (beside adding more flash memory to C?
