Coping with embedded "BIN" objects in MS Office documents
When I published a procedure for getting at embedded objects in Microsoft Office documents, I mentioned that older documents in MS Office 2003 formats could be saved as Office 2007/2010 equivalents in order to access the embedded objects via Windows Explorer after renaming the extension to ZIP. What I failed to mention is that older format embedded objects are stored with a BIN extension, not the proper extension of the application with which they are associated. The icon above, for example, is for an embedded PowerPoint 2003 slide.
There are a few ways of dealing with this. If you know what the object should be, just re-name the extension to fit (PPT in this case). Or if you are importing to a CAT tool, specify the proper filter for the *.bin file. Here's an example for memoQ 6:
The number at the end of the file name before the extension indicates the order of the objects in the document, which may be helpful in identifying the new extension to use. If you want to put the translated objects back in the embeddings folder, remember to change the extensions of the older objects back to BIN.
