Upack Unpacker Plug-in
PE Explorer ships with the Upack Unpacker plug-in, a start-up processing plug-in for unpacking files compressed with Upack or WinUpack. Upack is a packer similar to UPX, but it uses LZMA compression. All versions of Upack are supported.
Now you can open files compressed with Upack even without knowing that!
When you open a file with PE Explorer, the Upack Unpacker plug-in detects whether this
file is packed with Upack, and then unpacks it automatically. The resulted file will also be saved unpacked. PE Explorer does not re-pack the previously packed files back to the exact original size. That is why the original file size may be increased after you save the executable WITHOUT making ANY changes to it in PE Explorer.
The Upack Unpacker displays lines of messages in the bottom log window as follows:
Write Your Own Custom Plug-ins
The Upack Unpacker plug-in unpacks only files compressed with Upack. Consult the PE
Explorer help for the plug-in API: you can write your own custom start-up processing
plug-in for crypted files handling or unpacking the packed files. Using the Plug-in
Manager, you can set priority of executing plug-ins: Menu Tools | Plug-in Manager.
Within the PE Explorer directory there must be a subdirectory named PLUGINS. All plug-ins (DLLs) should be placed in this folder.
The plug-in API will be extended, therefore when writing custom plug-ins, it is
important to pay special attention to the remarks made in the description of Functions
and Types (see the product help file), and abide by them. Following these guidelines
will keep your coding compatible with future versions of PE Explorer.
