| 109 | + Suggestions :------ |
| 110 | + Usage - python file_finder.py <path of folder1, path of folder2, .....> |
| 111 | + folder1 - Parent Folder |
| 112 | + folder2, folder3 .... - Subsequent Folders |
| 113 | + Comparisons are done with in the folder, and from Parent to Subsequent Folders. |
| 114 | + |
| 115 | + No Files are deleted form Parent Folder but the files which are Duplicate to the files in Subsequent Folders are |
| 116 | + deleted. Make sure that the paths are correct |
| 117 | + |
| 118 | + Be careful during Keyboard Input. |
