Hard disk is full, and his size is not changing anymore, even if I delete documents in M-Files (500 Go)

If the vault uses Microsoft SQL Server as the database engine and you store the file data in a file system folder (instead of the vault database), you need to manually run the Optimize Database (Thorough) operation. This is the only way to remove any destroyed files from the file data server in this type of setup.

Thanks Joonas, I will take a look at this.

best regards

Also do note Joonas' use of the word "destroy" vs your use of the word "delete".  These are two different operations; deletion is not sufficient.

Yeah, you're right, I want to say destroy documents in M-Files,

thanks,
