Frequently Asked Questions

UDF (Universal Disc Format) is a file system standard used on DVDs, Blu-ray discs, and some newer CD-ROMs. It replaced ISO 9660 for most optical media after 1995, supporting larger files and longer filenames.

ISO 9660 was designed for CDs with 8.3 filename limits. UDF supports files over 4GB, filenames up to 255 characters, and better metadata. Most DVDs and Blu-rays use UDF, while CDs typically use ISO 9660 or both.

This viewer shows contents. For extraction, use our UDF Extractor which can download individual files or create ZIP archives of the disc contents.

UDF 1.02 through 2.60 used on commercial DVDs and Blu-rays. This includes plain UDF and UDF Bridge (UDF + ISO 9660 hybrid) disc images.

Yes, you can browse the file structure of DVD images. VIDEO_TS folders with VOB files will be visible. For playback, extract and use a video player or our VOB to MP4 converter.

Blu-ray UDF images can be browsed. The BDMV folder structure with M2TS files will be displayed. Large Blu-ray images may be slow due to browser memory limits.

No. All processing happens locally in your browser using WebAssembly. Your disc images never leave your device.

Common extensions include .iso, .udf, .img, and .bin. The tool detects UDF format automatically regardless of extension.

Some UDF images use packet writing or special formats. Standard read-only UDF images work best. Multi-session or incremental UDF may not display correctly.

Browser memory limits apply. DVD images (4-8GB) work on most devices. Blu-ray images (25-50GB) may require significant RAM.
