Case 1: How to Convert ISO Image to USB Friendly Format for Storing/Playing Purpose

Some people opt to back up DVD as ISO file to save physical space and protect DVD disc from damage. Afterwards, they would choose to copy ISO files to USB drive in such a way to back up movies, carry the movie library with them while away from home, and play them on smart HDTVs, other computers, laptops, tablets or other USB-compatible devices via USB thumb drive.

However, you may fail to copy large ISO file to USB drive because the flash drive is formatted with the FAT32 file format, a large amount of memory will be occupied (an ISO file always takes up several gigabytes). What's more, almost all devices can't play ISO files from USB drive natively. So, the best way to copy ISO file to USB drive is to convert ISO file to a USB flash drive friendly file format and a widely-accepted format, like MP4.

It is an easy work if you have an ISO converter in hand. If you don't have one, WinX DVD Ripper Platinum could be a good option. This software can convert ISO file to MP4, ISO to MKV (on Mac), AVI, WMV, MOV, 3GP, MPEG, HEVC, FLV and more popular file formats on Windows 2000 and later, including Windows 7, 8, 8.1, and Windows 10. It features No. 1 fast converting speed thanks to Multi-core CPU use, optimal configuration for newest CUDA and i5 i7 CPU, Super Encode Engine based on MMX- SSE & 3DNow! and Hyper-threading technology. No need to worry about quality loss, since the built-in High Quality Engine ensures crisp videos.

2. The output file will basically reserve the original high quality, since MP4 has high compression ratio.
3. MP4 format is more compatible to most playing devices and media, so you can play it unrestrainedly.

Limitation:
1. The resulting file does not contain DVD menu or the similar thing.
2. If you want to burn the MP4 file to a DVD, you have to rely on a DVD burning tool, such as Freemake and DVD Author.
