Skipping directory, also known as directory skipping, is a technique used in computing to improve file access performance. It involves reading or writing data directly to a specific block on a storage device, bypassing the traditional directory structure.

Skipping directory offers several benefits. First, it can significantly reduce the time it takes to access data, as the system does not need to traverse the directory hierarchy to locate the desired file. Second, it can improve data throughput, as data can be transferred directly to and from the storage device without the overhead of directory lookups. Finally, skipping directory can reduce wear and tear on storage devices, as it eliminates the need for repeated directory updates.

Skipping directory has been used in various storage systems for many years. It is commonly employed in enterprise storage arrays, solid-state drives (SSDs), and high-performance computing (HPC) environments. As storage devices continue to evolve, skipping directory is likely to become even more important in optimizing file access performance.
