Find Duplicate files using Vb.Net

Finding a duplicate file by file name may not be sufficient. Hence we need to compare by file data. The file might be renamed and may look like a different file. But when comparing with content of the file, we may notice that the file is a duplicate.

To find duplicate files even renamed, the content has to be compared after the content of files fetched. Once the file content is in data format, the data can be encoded with MD5 hash algorithm. The string result after hash can be used for comparing.

.NET Framework has very rich support for encrypting and decrypting, such as computing hashes and encrypting data using a variety of algorithms. Use the ComputeHash() method to compute the MD5 Hash. yes it can not be simpler than this.

This same function can be used in a recursive call to check all the duplicates. Once all the files in the directory are scann ...

.Net has excellent support for multi threading as it helps programming much easier when co ...
