Add Extra Features : The selected the any wim file opens as writeable on the the c:\MountUSB folder. This opens the A43 file manager to access this folder. That way, if you want you can add what you want. When you close the file manager, the things you added are saved to the destination file. Of course, this feature is optional.
Format Usb Device : This option will help you take the format to the target usb device. For this program currently not used Grub4Dos manager. So the format type should be ntfs for the Bootmgr file. I used two files to activate the boot feature of the usb device.
To put it crudely:
MbrFix.exe setactivepartition /yes
Extract Boot.Wim (not recommanded) : The destination wim file opens as be readable to the C:\MountUsb folder. Then the files in this folder are copied to the target usb device. I think, if physical ram is less, this feature can be used.
Set FilePath : If the target files (*.wim, BCD and BootMgr) are used by the program in different paths, you can use this feature. The paths of files is saved in UsbPE.ini .
Set DirPath : If the target files (*.wim, BCD and BootMgr) are used by the program in same path, you can use this feature. The path of the source is saved in UsbPE.ini .
But if you do not use these two features, The program has to be in the same path with the target files.
You can use these two features with the command-line.
UsbPETool.exe /DirPath "c:\Target_Dir Path"
UsbPETool.exe /FilePath /bcd "c:\Target_Dir Path\Boot\BCD" /bootwim "d:\Target_Dir Path\Leopard\Leopard.wim" /bootmgr "d:\Target_Dir Path\BootMgr"
