OLE Object optimizing: looking for cmd tools

[Psykauze]

Dear all,

I have made a tool for my company for optimizing some files like Zip, jpg, png and docx/xlsx.

The way it is optimizing the files is simple: It extract the zip/docx/xlsx file, then it search the jpg/png/docx/xlsx files inside to perform recursively the optimizing process (I'm using advzip, pngopt and mozjpeg).

But inside the docx files, embedded zip are embedded inside OleObjects that I can not open.

Is there any tools (command line tools) that can extract the oleobject embedded file and replace it with a new version ?

Hope, you can be helpful. Thank you.

Maybe you can try FileOptimizer
Anyway Leanify and ECT will do more or less the same.
As for OLE I am afraid of not being able to find anything other than Document Press.

My tool is nearly as much efficient than FileOptimizer. I double checking that tomorrow.

Yes, I've checked that and I tried to use the 6.02 docprc with my tool but it look like it didn't do something.

Thank you.

Good!
Hope you are able to share it.

It is a crappy batch script so I do not want to share it but:
- For jpeg, I am using mozjpeg (-perfect -copy all -progressive -optimize)
- For png, I am using optipng -o7
- For zip-like, I'm using an old version of advzip because it is more efficient when you zip a zip file with the old version than the new version. (My tool is better of 0,25% than FileOptimizer for docx files)

(Maybe we can combine the old advzip for embedded zip and the new for final zip/docx)

Also, I found this https://github.com/decalage2/olefile
But it need a python environment and I have not tested it yet.
