fsctl

About this tag
The fsctl tag covers discussions about file system control codes (FSCTL) in Windows, particularly in the context of Server Message Block (SMB) connections. A recurring issue involves internal FSCTL requests being incorrectly sent as IOCTL requests during offline file synchronization in the CSC folder. This behavior can lead to unnecessary network traffic and performance degradation. Microsoft has addressed this with a hotfix (KB2733363) to ensure proper FSCTL handling over SMB. The tag is relevant for IT professionals and system administrators troubleshooting file synchronization, SMB protocol behavior, and Windows file system internals.
