Although basic text files contain no metadata, the following tags are determined from a simple analysis of the text data. LineCount and WordCount are generated only for 8-bit encodings, but the FastScan (-fast) option may be used to limit processing to the first 64 kB, in which case these two tags are not produced. To avoid long processing delays, ExifTool will issue a minor warning and process only the first 64 kB of any file larger than 20 MB unless the IgnoreMinorErrors (-m) option is used.
Tag Name Writable Values / Notes ByteOrderMark no 0 = No
1 = Yes
LineCount no MIMEEncoding no Newlines no "\x0a" = Unix LF
