Hello,

I'm using a 3rd party SDK to read ost/olm files, no problem using it, just have a question about the general structure of such ole2 storages?

My 1st question: Found that there are IPF folders in addition to IPM inside PST file:

https://learn.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-oxosfld/68a85898-84fe-43c4-b166-4711c13cdd61

https://learn.microsoft.com/en-us/previous-versions/office/developer/exchange-server-2010/bb891841(v=exchg.140)

Should I behave IPF items exactly like IPM counterparts?

ie, save using the same method for both IPM.CONTACT and IPF.CONTACT as contact file?

or IPM.NOTE and IPF.NOTE as message? the same?

My 2nd question would be that according to MS, IPM.Document is for DocumentItem, which can be ANY kind of file, even executable etc

Didn't find its IPF counterpart, but found IPF.DocumentLibrary / IPF.ShortcutFolder which I don't know what's that for? The same as IPM.Document?
