 ## Done
 - Basic menu(need refactoring)
-- Duplicated file finding
+- Duplicated file finding - CLI
   - Including and excluding directories(absolute pathes)
-  - Option to remove file
+  - Option to remove files in different ways
   - Fast(by size) or accurate(by hash) file checking
-  - 
 
 ## TODO
-- Duplicated file finding
-  - saving to file
+- Duplicated file finding - CLI
+  - saving results to file
   - support for * when excluding files and folders
-- Graphical UI(GTK)
+- GUI(GTK)
 - Removing empty folders
 - Files with debug symbols
 - Support for showing only duplicates with specific extension, name(Regex support needed)
+- Maybe windows support, but this will need some refactoring in code
