Okay, I thought the original poster meant that
(s
)he copied the CABs to the device and then couldn't find them there.
(In CE 4.x .net and CE 5, newly added files sometimes don't show up the first time you open explorer.exe.
If you want to keep the CAB file after executing it, an easier way is just to select the CAB file
(single-tap on it
), open File -> Properties, and check the box marked "Read-Only."
