A: I had this exact problem as I tried to extract an Intel NIC installation package so I could manually force a driver installation. I tried /e, and it gave no indication of where the expansion had written to.

The secret is to also add the /f switch, which tells the process where to write the extraction. For example,

`d:\temp\PROWinx64.exe /e /fd:\temp\intel`
Note that there's no space between the /f and the path.

For storage drivers, the /e switch doesn't work, so you need to use

`-a -n -s -p `
after the storage driver file.
