They usually contain substantial amount of redundant items. This paper addresses the Information Retrieval issues by today's hierarchical systems such as file systems. For this analysis we have taken File Renamer Basic, Flexible Renamer, Advanced Renamer, Batch Renamer, Bulk Rename Utility, Rename It, File Renamer, and Effective File Search. The main objective of this research work is to analyze the performance of eight open source file renamer tools. For performing the file renaming process there are many open source tools are available. It is very difficult to the users for renaming the file names after reviewing the content of each and every file. This situation has created a problem to the users if they are searching for particular information or content from these files it is very difficult for them to get the exact file and this process has become tedious, time and memory consuming one. Later, the computer system contains many different categories of files, and the name of the files does not provide proper meaning. These file names may be a combination of numbers or numbers with special symbols or only alphabets with no meaning or alphabets with special symbols or combination of these.

Generally, most of these downloaded file names are not giving any proper meaning.

Enormous growth in the internet technology and the advanced developments in the hardware industry has created a new platform which helps the users to download and store large amount of information in the form of word documents, PDFs, text files, images, audio files, and so on.
