Btrfsmaintenance vs WinContig

Btrfsmaintenance is a free set of scripts for automating maintenance on Btrfs filesystems. It can run scrub, balance, trim, and defragmentation, with separate settings to enable, disable, and configure each task. Scrub reads filesystem data and metadata to check checksums, which can reveal hardware problems or bit rot; when a good redundant copy exists, it can repair data automatically. Periodic jobs can be scheduled with cron or systemd timers, though only one scheduling method can be active on a system. The project supports widely used distributions, provides installation guidance for Debian-based systems, and describes manual installation for others. On SUSE-based distributions, a zypper plugin can defragment RPM database files after package installation. Settings are designed for a default installation with Btrfs on the root filesystem and can be changed in the sysconfig file. Scrub may create intense read activity, and balance can use substantial read and write resources; task concurrency can be serialized to manage impact. Directory defragmentation does not descend into other mount points, nested subvolumes, or snapshots, which need separate paths listed. It is licensed under GPL-2.0 and available for Linux and self-hosted use.

WinContig defragments selected files or folders, so you can process frequently used items without defragmenting an entire disk. It is a Windows standalone executable: no installation or additional DLLs are required, and its files and settings stay in one folder. It supports FAT, FAT32, exFAT, NTFS, and ReFS on internal and external HDDs and SSDs. You can save groups of files and folders as profiles, use command-line switches in scripts or scheduled tasks, and add optional analyze and defragment commands to File Explorer. WinContig can also scan for file-system errors, retrieve S.M.A.R.T. data, and remove temporary files before defragmentation. It supports Windows Vista, 7, 8, 8.1, 10, and 11, along with Windows Server 2008, 2012, 2016, and 2019, in 32-bit and 64-bit editions. It needs 6 MB of free disk space and administrator access. The Freeware plan costs nothing, with personal and commercial use on unlimited Windows computers and no registration or payment.
