How to write files to your desktop with the use of an android application using an emulator or USB-connected device using for example Android Studio?

I wrote some classes for my Android-program and it runs. However it takes too much ram because the data in the File is not in a nice form to be processed by the application. Let's call the File Foo.txt for now.

I now want to save the data from Foo.txt in a different form which lets my Android specific code (specific in the sense that it uses Activities, Context etc) do easily since I have all the code for it already, and then load from this data manipulatedFooFile.txt instead. Problem is, I don't know if it's possible at all to save to a file which I can then later retrieve on the desktop, either in an emulator or via a device connected to an USB or a way I don't know of yet. This way I can replace Foo.txt with manipulatedFooFile.txt which would let me use less ram and space on disk.

I know that one other solution would be to remove the code from android and put it into a normal java program. Put that would take a bit of struggle since I have to remove all the dependencies on code that is not there, or start with nothing and write big parts of the code again.

Files and folders can be sent to and from your android device using adb (or android debug bridge).

Using the adb pull command under the syntax adb pull <remote> <local> you are able to transfer a file from the filesystem of the connected android device to your local device (your computer).

From the official documentation for adb pull:

Copies a specified file from an emulator/device instance to your development computer.

Similarly, adb push allows you to push a file from your local computer to the target emulator/android device under the syntax adb push <local> <remote>.
