HOWTO Best Pratice for formatting SD- / MMC-Cards and Image-Handling e.g. Tools for Resize

Could you please tell me your experiences with handling images of SD- and MMC-Memory-Cards for Emulation.

I use Windows 10 32-Bit as PC-OS, but you can tell for Tools for Linux, Mac and so here.

Tools wanted are for creating empty Image-Handling for different formats like .HDF or RAW-Formats and Interfaces like divIDE, divMMC and OS like esxDOS.

Tools for resizing Images, extract Files, stuffing/inserting files and directories, displaying partition information. And verifying disk-structures. From commandline (prefered by me) or with GUI.

And tools for creating dumps of Memory-Cards and writing them back from Image to MemCard.

Together with links to websites with good informations and manuals about this all

Thanks in advance!
