About
blob stands for binary large object and represents the file content in binary data.
Because in a computer, all data are binary data, this name is used logically to represent any file content where the mime (type) is unknown.
Encode / Decode
All files are blob and this is the role of a third application to retrieve the binary content and then decode/encode it in the target mime (type).
For instance, if this is text data, a text editor would retrieve the binary content and would decode it into text.
File System
If a file system indicates that it's a blob storage system, it indicates then that it may store any type of content (ie any mime)
Most file system does:
- from the local file system (os)
- to database
- or any programmatic language (javascript blob)
- and any edge object storage provider
