How do I defrag a SQL database file?
With the contig -a option you can analyze the fragmentation of a specified file with the database online. To defrag the file simply run Contig [FileName]. Needless to say that in order to defrag a database, the database file must be OFFLINE.
Which is faster database or file system?
As a general rule, databases are slower than files. If you require indexing of your files, a hard-coded access path on customised indexing structures will always have the potential to be faster if you do it correctly. But ‘performance’ is not the goal when choosing a database over a file based solution.
Does defragging damage hard drive?
Defragmenting only does not put extra wear and tear on your hard drive, but because of its performance boosting effects; it will actually make your hard drive perform better. Defragmenting and cleaning old files from your hard drive regularly will help extend the usable lifespan of your hard drive.
What can lead to file fragmentation in a database?
Let’s see what can lead to file fragmentation. Many mid-sized organizations, to reduce costs, share the database server with other applications like SharePoint or a web server. In this scenario, the file system could be fragmented regardless of the database. And when the database needs to allocate disk space, it could be scattered.
Why are there so many fragmentation issues in DFS?

Which is a special case of file system fragmentation?
