Sitefinity allows you to use two types of blob storage providers:

• FileSystem storage provider

• Database storage provider

FileSystem storage providers keep the whole files into the file system at the location that is specified in the BSP settings. In the specified folder Sitefinity stores binary files with Guid names. If draft and published version differ, there are two files per item.

Database storage providers keep the blobs into chunks that have FileId and ordinal.
