Hi,

for a good useabillity of my programs i want to write a little Patchengine to release updates with a small filesize.

Any ideas how to code an Filepatcher (offset patching) with PB?

I suggest that there are may ways to create a "FilePatcher". If I should create such one, I would create an own "FileType". My app should do the following things:

- Compare Source Data with Destinationdata
- Store only- changes to a file.

Now you have to create the File-Patcher which is able to read your Patch-File and apply these patches to your original one. After patching, there should be a 1:1 copy of your secondary file.

Nice project that you are started there. Wish you fun. )
