Simple application (Microsoft Visual Studio), C# - finding/searching files

Hi, Today I have simple application to do. You can choose programming environment: - Microsoft Visual Studio and Windows 8 or - Xamarin and Mac OS X and Windows What application should do: search for specific string in file's names and put output (list of files containing string) in list (table) Similar like 'find' command - you inform where and what should be found: find /usr -name local /usr/libexec/postfix/local /usr/local /usr/share/zsh/5.0.8/help/local A. FIRST window: 1. Search field 2. Directory structure (you can mark where it should look for files) 3. Button OK 4. Menu (File -> Configuration (open configuration window), Print (print list of founded files), Exit ; About) B. SECOND window (output): List (table) with founded files. List should have position like: - filename - size - location - last access date List should be possible to sort by filenames, size, extension (+filename) It should be possible to mark one or several files (all files). After clicking right button on specific file(s) in table in pop-up menu there should be position like: Open -> open the file Move to -> it should be possible to move file(s) to specific folder Information -> detailed information about file Delete -> delete C. Configuration Here you should be able to choose which files (with specific extension) should be founded. You need to put file's extension you want to find (configurable list with extension and description - you should be able to add, delete, edit extensions) For example: if I put extensions like: AVI (*.avi movie) MOV (*.mov movi) WAV (*.wav audio) it should search for files with these extension (avi, mov, wav) only and search for specific string in founded filenames. So, If after searching it founded : [login to view URL] [login to view URL] [login to view URL] [login to view URL] output after putting string "scary" should be: [login to view URL] [login to view URL] [login to view URL] D. About Here you put information about author. That is all. After everything is done I will provide polish name and you have to replace english words with polish names. Of couse I expect to get full source code well commented Please, write me how much you want for this simple application and how much time you need to finish it.
