Why c² flux is so fast
c² flux is designed to avoid unnecessary file system work and automatically uses the fastest available scan method.
The first scan may take longer because all file and folder information must be read.
Later scans can be much faster because c² flux uses cached data and only checks for changes.
When c² flux runs with administrator rights, it can use the NTFS Master File Table.
The MFT is Windows’ own file system index. Instead of opening every folder one by one, c² flux can read file and folder information directly from this index.
This usually means:
- fewer file system calls
- less waiting
- lower overhead
- very fast results, even on large drives
If MFT access is not available, c² flux automatically switches to another fast Windows method or, if necessary, to the normal scan mode.
Speed never comes before reliability.
