When you copy a file from a zip (integrated zip function) to any folder in
c:\program files\ in order to replace a file, the copy fails and the target
folder will be empty! You lose the files!

reproduction steps:
1. suppose in c:\program files\app1\ you have these 3 files:
file1.exe, file2.dll, file2.txt
2. suppose in your Documents folder you have a zip contains file1.exe
3. explorer the zip and copy file1.exe to c:\program files\app1\
4. give the UAC consent
.... but the copy will fail and the whole app1 folder will be empty. COPY IS
FAILED AND YOU LOSE OLD FILES.

Hmm, step for step I couldn't duplicate the problem.
