I am developing a small windows XP application that iterates over a set of files in a folder and extracts information from the files properties (right-click, select properties and then the summary tab) like title, summary etc. The article Microsoft Knowledge Base Article - 186898 shows how to do this for compund docuemnts like Word documents and so on, using IPropertyStorage. However, In my application, I access non-compound documents (jpeg-files mostly). They can also have attributes like the office files, but IPropertyStorage doesn't seem to be the right choice for finding the information. Does anyone have any excpreience with this?

Thanx Michale for your help! It got me almost there... I have now extracted the information I wanted from all the Office documents in my application. The thing is that I also need to do the same thing for a bunch of JPEG-files. Reading the article You proposed, I understand that IStorage and IPropertySetStorage only applies for compund documents, such as the Word documents You helped me inspect. The JPEG files aalso have properties like this - is there another way to access their properties:confused:? Or is their properties stored elsewhere than in the file? Once again, thank you :-D Jonas Pettersson

For any office document and many other documents as well, you can edit the document's set of properties by right clicking the document's icon, and selecting the summary prop-page. There are for instance etries like "Document title", "Comments" and "Keywords". In my code, I would like to access this information. That is, given a filename, I want to check if the correspondning file has an entry "Comments" and reads its value. Can anyone with this knowledge share some hints or, ;P even better an example?
