+# rename_lowercase
+
+This task takes a folder of files and copies them to a new folder with all filenames downcased. 
+
+Using default:
+
+- Put your files into the "objects/" folder.
+- Open terminal and type `rake rename_lowercase`
+- All files in "objects/" will be copied, filenames converted to lowercase, and output to a new folder "renamed/". (nothing will be deleted!)
+
+
+| option | description | default value |
+| --- | --- | --- |
+| input_dir | the name of the folder containing the files to be renamed | "objects/" |
+| output_dir | the name of the new folder to put the renamed files | "renamed/" |
+
+
+The order follows [:input_dir,:output_dir].
+For example, 
+
+`rake rename_lowercase["raw_folder","new_folder"]`
