Merging two binary files

[parasoul]

Hi,
How do you suggest the best way to merge two binary files using NSIS?

My first instinct is to use FileRead,FileSeek,FileWrite, but as I understand it, if the buffer of data is greater than the maximum string length then it wouldn't capture all of the data

My next instinct is to use the system plugin and use localalloc to create a buffer and then call CreateFile/ReadFile/WriteFile via the system plugin. I really want to avoid doing it this way because it would be pretty messy.

Do you know of a more elegant way?

I appreciate the help
