There is only one file type that uses the .MD5.TXT extension:
Message Digest 5 Hash File
File created to test downloaded files for errors; the Tiny Core Linux operating system retrieves a MD5.TXT file for each .TCZ before downloading it; can be removed but does not need to be.
An example of an MD5.TXT file and TCZ file is when sstrip.tcz is downloaded and sstrip.tcz.md5.txt is created.
NOTE: Any MD5 calculation or comparison program will use this file.
iso.md5.txt - File can be found in the root of the Tiny Core operating system.
