e2freefrag

e2freefrag is a command-line tool that is used to analyze the fragmentation level of files in an ext2, ext3, or ext4 filesystem. It is designed specifically for Linux-based systems and helps users understand the fragmentation status of files stored on these types of filesystems. The tool calculates the fragmentation percentage for each file and presents it in an easy-to-read format. e2freefrag uses a simple algorithm to determine the fragmentation level by analyzing the placement of file blocks within the filesystem. The tool also provides information about the average file size, free space, total files, and total blocks in the filesystem. Users can run e2freefrag with the "-v" option to get a verbose output that includes detailed information about individual files and their fragmentation levels. e2freefrag does not modify or change the filesystem; it only provides read-only access for analysis purposes. The tool can be particularly useful for optimizing data storage, identifying heavily fragmented files, and making decisions regarding file defragmentation strategies. e2freefrag is a lightweight and efficient tool that can be easily integrated into scripts and automated workflows for regular fragmentation analysis. It is an open-source project and is readily available for download and usage in various Linux distributions.
