Download file from DB using FileAccess.DecompressData


I have a problem regarding an old activity in UiPath that is no longer available (package ActivitiesDecompressRPA).
I need to acces a DB (done), get the DB info and assign it to a datatable type variabe (done), and then download the content (in my case a .jpg file).

In the past i used the ActivitiesDecompressRPA package, but it is no longer available.
Now i need to get from each line of the datatable the information which i decompress and then i need to execute FileAccess.WriteBytes in order to phisically create the file locally.

Any ideas how can i get it done?

I get to the point where i have de datatable and the address of the file, but i need to decompress it and then save it locally.

Thank you!
