hi
i am trying to use the Callbackdisk Procuct....and what i would need is like a changelog
everytime a file or folder gets created, changed, deleted or renamed (i dont care about read) i want to put that file on a list ....simple changelog.

and a sexond Question:
how can i read a single file using code from the virtual disk ?

Any clue how to solve that?
thanks Alex

CallbackDisk emulates virtual disk, not a file system. It operates with sectors of the disk. So it knows nothing about files. You can apply CallbackFilter (which is currently on Beta 1 stage) to the virtual disk and be notified about any operations. Alternatively you can use Callback File System and implement your own virtual disk and a virtual file system in user mode. In this case you will get requests for file operations and you will be open to both implement them and log them.

Generally CallbackFilter was designed for tasks like yours. But it's quite unstable at the moment.

Using Windows API. Warning: you may not attempt to perform any operations related to the virtual disk (such as read the file located on such disk) from callbacks.
