Decrypt/Read/Modify “.automaticDestinations-ms” and/or ".customDestinations-ms"

Question

Does anyone know how to read the files Microsoft creates for JumpLists?

I want to clear from JumpList all history/most visited/recently closed, WITHOUT clearing up the tasks.

I tried to use the APPID from win7api, and clear for example, google chrome's jumplist. But with "ClearAllUserTasks" method it clears EVERYTHING from the jumplist, even the "Tasks". The same thing is with deleting the file.

Isn't any way of knowing the format of the *destinations-ms files, so I can modify them myself? Basically, wanting to clear just history/most visited, but couldn't find anything in Windows 7 Api (nor C++ or .NET).

Solution 1

The file is a Structured Storage file.

Solution 2

The OpenMCDF project is capable of reading and basic editing out of the box and you can easily create a specific tool with the library.

After some experimentation, I realized the .automaticDestinations-ms are Structured Storage files as the answer says. However, .customDestinations-ms are not. Luckily, I noticed that for what I'm doing (creating custom pins in Windows Explorer), custom is what i need.

Seems that customDestinations-ms have now been converted to Structured Storage too. What a pain. Quick Access is so inflexible now...
