Appender
Introduction
Appender is a tool for adding, reading and exporting additional resources.
What is the use of Appender?
- The most typical is that some software can generate exe files from some data stream files, such as some mp3 generators, Flash generators, and S-demo for animation. Their function is to bind data to PE;
- Can be used for installation package production, use this program to attach the installation package to a custom program, and release resources during installation;
- Can be used to hide files, such as adding files to pictures and other formats;
Will the increased resources occupy the running memory?
-Overlay is appended to the back of the file and is not mapped to the data in the memory space. It provides its own program to open it for reading -Overlay is just data, it is not mapped to memory, it will be read by the program in its own way
How much resources can be increased?
- 4GB is a hard limit for all portable executable programs (32-bit and 64-bit PE)
- Other formats (such as picture formats) generally do not have this restriction
How to ensure the integrity of resources?
Appender will check if the resource length is consistent before releasing the file, and will also perform a second check after release.
Use
We use the resource ID to mark the file. The resource ID can be any text less than 64 in length, and no repetition is allowed.
Increase resources
Appender.exe add targetFile resourceFile resourceID [newFile]
- Basic usage:
Appender.exe add D:\Program.exe D:\file.zip Archive - Output new file:
Appender.exe add D:\Program.exe D:\file.zip Archive D:\Program-new.exe - Set compression (0-9 level):
Appender.exe add D:\Program.exe D:\file.zip Archive -c 5
Release resources
Appender.exe export targetFile resourceID outputPath
- Specify the output path (keep the original file name):
Appender.exe export D:\Program.exe Archive D:\ - Specify the output path (custom file name):
Appender.exe export D:\Program.exe Archive D:\file.zip - Export to the target file directory:
Appender.exe export D:\Program.exe Archive file.zip
