u have to give a name to te project and u can switch projects with the down arrow bellow the CRB of the left
CRB will create a folder called projects inside the path of the program, inside of the folder u will be able to see folders with the names of the projects to delete a project just select the "delete project" button from the left panel first button, select the project and the recycle bin

Tip

In the left panel seccond button we have a option with the icon of a folder, if we touch on it u can enter to the folders of the project

unpack our firmware

in he left panel first button we will select "Extract ROM (auto)" button, bellow the black rectangle we will see 2 buttons, the first is to select the firmware/ROM file and the seccond is to extract it
it will give for us inside the project path a folder called "Output" that will have folders with the names of the extracted partitions, inside these folders we will find all the files stored on that unpacked partition

Delete partitions

in the left panel first button you will find a option called "Delete partition"
this option is helpful for cases like GSI where the product partition has no sense to be included and can be deleted to maximize the size of the system partition, to do this go to to the Delete Partition button after extracted the rom and them select the partition and touch the Recycle Bin icon

    • Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
