Adding Files to a bootable USB

Hi ...
After creating a bootable USB  using "etcher" utility from ISO files on a USB flash drive, the USB drive becomes the same size as the ISO file and cannot add more files. Moreover, inserting it into Windows OS , the usb key is not recognized anymore. Is there a better utility supporting any kind of bootable ISO files and still be useable to add more files to it.

Thanks

In order for Windows to recognize it you have to format the USB stick using a filesystem windows recognizes such as fat or NTFS.

If the USB stick is formatted with ext4 for example windows won't recognize it.

Rufus is my favorite tool for bootable USB stick creation. Check via Windows Disk Management in which file system the drive gets formattef once you create it.

I use unetbootin. I've used it to burn a number of distros, including Knoppix.
You may have a problem if your PC is enforcing secure boot - I turned that off on my system..
