PassMark Fragger

PassMark Fragger 1.0 by PassMark Software is a specialized disk utility designed to give administrators, testers, and power users precise, repeatable control over file fragmentation and defragmentation processes inside a controlled Windows environment. Instead of waiting for natural fragmentation to occur, the program lets the operator choose target files or folders, set the desired number of fragments, fragment size distribution, and free-space placement, then executes the operation instantly. Conversely, it can defragment the same dataset with equal granularity, making it possible to compare before-and-after states at the file-system level. These capabilities turn the application into a practical benchmarking platform for evaluating third-party defragmentation tools: identical, synthetically fragmented test beds can be created in seconds, processed by any external optimizer, and then rescanned so that performance metrics such as consolidation ratio, elapsed time, and resource consumption can be measured objectively. Typical use cases include validating the effectiveness of enterprise defrag solutions, reproducing customer support scenarios, producing repeatable demonstration data for training or documentation, and stress-testing storage hardware or backup software under highly fragmented conditions. Because every parameter is user-selectable and logged, test sequences can be scripted for overnight regression runs or compliance audits. The software belongs to the System Utilities / Disk Tools category, complements PassMark’s existing suite of performance analyzers, and operates exclusively on NTFS and FAT32 volumes within Windows XP through Windows 11. PassMark Fragger 1.0 is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always offering the latest build and supporting batch installation alongside other applications.
