Just remember that MD5 taken on an arbitrary length of data and
gives back the 128-bit hash value. Rest of the working is same as the SHA-1 as explained above. It is based on the Markel Damgard Construction and also based on the iterative manner to produce hash. For padding it divides the file to 64 bytes of equal length of blocks and it appends the value to 448 modulo 512 and takes on4 words (A,B,C,D) to process the round functions.

Two files are being generated with different messages but their md5sum is same. This cannot be possible as theoreticians said. But below in the Snapshot you can check POC, that this can also be possible. Now below I am just showing you a very toy example that how these can be exploited but there can much more dangerous things that can happen with large firms like Banks, Security Agencies, Companies etc who uses MD5 hashes and similar to its level which is shown
