besides file name what meta data do a plain text file contain ?
Metadata is created anytime a document, a file or other information asset is modified, including its deletion. Accurate metadata can be helpful in prolonging the lifespan of existing data by helping users find new ways to apply it. Metadata organizes a data object by using terms associated with that particular object.
If you want to add metadata support for text files, say, then all you have to do is scroll the left-hand “File Extensions” list, select the TXT file type, and click “Add File Meta Handler”.
Depending on the usage of the file, it might contain some metadata -- for example, a script file might indicate the program used to run the script at the top -- but in general a plain text file doesn't contain metadata itself.
Right-click on the file. View its Properties. If there is metadata that you would like to remove, select the Details tab. Click Remove Properties and Personal Information.
I can think of lots of metadata that even a plain text file has -- creator, size, permissions, last accessed time, last modified time, etc. -- some of which probably depend on which OS you're talking about. I'd suggest looking at the directory operations and/or the file data structures in the system libraries on the particular OS for a more complete list for each particular OS.

What file system? Strictly speaking, a "plain text file" doesn't contain any meta data, not even the name of the file. All of that is handled by the file system.
On Linux (not in the file content, but in the filesystem):
There are a few others (like a readonly flag), but you will usually not need them.
