> I don't know how Windows stores short files,

By Windows I Think you did mean NTFS.
Then yes, file data for certain short values is stored directly in $MFT.
This is not specifically file contents, and even if a file content is just 1
byte, not necessarily it will be stored in $MFT. It all depends on the entire
size of file metadata. If it does not exceed some-under-1K in total, then file
data may be stored in $MFT as well.
