Why would we not edit a large movie file on a CD ROM?

Editing a large movie file on a CD-ROM is impractical due to the limited storage capacity and slow read/write speeds of CDs. CD-ROMs typically hold only about 700 MB, which is often insufficient for high-quality video files. Additionally, the lack of random access and slow data transfer rates can significantly hinder the editing process, making it inefficient compared to using modern storage solutions like external hard drives or SSDs.
