Can you restore a word document from 97-2003 only using its Compound File streams?

Question

I am trying to recover a word document that was using 97-2003 version. I do not remember why I did this, but I saved off the Compound File streams into a folder, and it is definitely something I would like to have back as the original document. Is there any solution for this?

Thanks!

Sure, you should theoretically be able to restore it.

You should be able to create a root compound document using

StgCreateDocfile() // or StgCreateStorageEx()

You will need the IStorage* pointer from this if it succeeds.

If you have a folder in your folder, you are going to have to create sub storages for each folder--and do it recursively. The API is IStorage::CreateStorage() ... look it up.

If you have a file in a folder, then a stream needs to be created in the storage that is equivalent to the folder. To create a stream, use IStorage::CreateStream()...look up arguments.

Looking at your screen shot, it has some streams named something like [1]CompObj or [5]SummaryDocumentInformation. For the [n] part, that is probably the equivalent of _T('\00n') where n is 1 or 5 or whatever--it's probably a control character. I've seen that in compound files. If you want to investigate, create a Word 97-2003 document and save as a .doc file and examine the structure.

So, something like [1]CompObj is really _T("\001CompObj")

The stuff above about [n] in your file names is an educated/experienced guess.
