It's going to be quite difficult to do at home without specialised tools and skill. Most phones don't show up as drives in Windows and even if they do, it's not a guarantee that any recovery software will have direct access to it like a normal drive in order to read the unallocated data.

It also depends on the type of phone you have, whether the data was encrypted, how long ago you deleted the files, etc...

Specialised tools exist to dump the entire contents of a phone's memory to a file, but those are *very* expensive and depending on the phone, only accessible to Government agencies.

If it's a Mediatek you can find it for free: SPFlashTool. Great way to backup everything bit-for-bit and restore from a brick, if you're into ROM modding and such.

I haven't worked with any other manufacturers' but I imagine they have similar "factory tools" that you might be able to find online.

If you only want to recover a small amount and have a rooted phone, then dd will work to get an image you can then work on. Most importantly, stop using it until you get that disk image --- or your chances of the data not being overwritten will continue decreasing.

Most don't. If you have an Apple product, they'll just tell you to use iCloud. All the big Android brands will tell you a similar story (use Google Drive, Dropbox etc...) to back up your data. The cheaper Android's are quite easy* to get entire memory dumps from, you might even be able to do this via ADB commands.

For phones like Samsung even uploading a custom boot loader can trip the Knox lock rendering your manufacturer's warranty void and inability to use Samsung Knox features like secure payments etc...

For newish iPhones (from memory, iPhone 5 onwards), they encrypt data by default and each file has its own individual 256-bit AES encryption key. Once a file is "deleted" that key is destroyed which renders that file completely unreadable and unrecoverable. The IOS Security Guide is a good read if you wanted to learn more.

* "Easy" as in inexpensive and simple for a technically-minded user, not "easy" in that any average user would be able to do it.
