I am often doing some cleanup in hard drives and I always want to know the size of each Folder in a directory in Explorer.  Each time i need to run a dir to know the folder size. I noticed that there is that option in windows explorer but why does the size of thoses folders is never showing up?    Thanks for your help

How can I visualize which folders and files are taking up all of the space on my hard drive?  I'm getting some conflicting reports on the size of hard drive contents. Namely what is and isn't there and what folders are actually using the space.   I need to know which of the files or folders the culprits behind all this hidden bloat. Also there should be a print option to get it on paper.

I got Total Commander on my Android phone.  I need to check the directory size for a folder and the solution is:  ..  I understand that but my question is how to add a new button to the button bar?

I've written the following routine to manually traverse through a directory and calculate its size in C#/.NET:    protected static float CalculateFolderSize(string folder) {     float folderSize = 0.0f;     try     {         //Checks if the path is valid or not         if (!Directory.Exists(folder))             return folderSize;         else         {             try             {                 foreach (string file in Directory.GetFiles(folder))                 {                     if (File.Exists(file))                     {                         FileInfo finfo = new FileInfo(file);                         folderSize += finfo.Length;                     }                 }                  foreach (string dir in Directory.GetDirectories(folder))                     folderSize += CalculateFolderSize(dir);             }             catch (NotSupportedException e)             {                 Console.WriteLine("Unable to calculate folder size: {0}", e.Message);             }         }     }     catch (UnauthorizedAccessException e)     {         Console.WriteLine("Unable to calculate folder size: {0}", e.Message);     }     return folderSize; }    I have an application which is running this routine repeatedly for a large number of folders.  I'm wondering if there's a more efficient way to calculate the size of a folder with .NET?  I didn't see anything specific in the framework.  Should I be using P/Invoke and a Win32 API?  What's the most efficient way of calculating the size of a folder in .NET?

I have an empty folder with regular details view. File name, file size, file type columns are shown and I am happy.   Then I put some MP3 or WAV files in. Windows Explorer "kindly" changes the column types. It will show Genre, media length, Album and other metadata tags, but does not show the file size anymore. If I do not like it, I have to manually change the columns back. It is very irritating.  How can I turn this automatic behavior off?

I understand the size reported by ls corresponds with number of inodes inside the directory, not their actual size.  I have noticed peculiar behavior, when displaying directory size with ls. Here is how to quickly reproduce it:  first create empty directory, the size reported by ls is 4096 (as expected)  mkdir test ll -d test/ drwx------ 2 root root 4,096  2015-Dec-29  22:22:36  test/   create 10,000 files inside. Size reported is now 167,936   touch test/{1..9999} ll -d test/ drwx------ 2 root root 167,936  2015-Dec-29  22:23:24  test/   remove all files. Size should decrease back to 4096  rm test/* ll -d test/ drwx------ 2 root root 167,936  2015-Dec-29  22:23:59  test/   But the size is still reported as 167,936.  why?  can somebody explain this?

Just something I ran into and couldn't think of a proper explanation. If I create an empty *.txt file on my PC and then look at its size, it shows 0. But how is that possible? I mean even if the file itself is empty, it still must have some size, just to store its own name. How can this be explained? (Non OS specific)

I must be missing something really obvious, but when in Nautilus, how do I create a new folder if the window is full of other folders/files?  Whenever I right click, only the context menu of a subfolder/file is given, as the window is full:

I have an external hard disk, and for some reason, it is reporting wrong free space.  In Windows Explorer, it is showing the used space is 378 GB.    I tried running chkdsk H: /f /r, it seems to report the same usage as Windows Explorer, and it says that there is no problem.    But when I tried selecting all the files inside this drive, it is showing much lesser usage.    I've already set the setting to show all hidden files and folders, also show the protected OS files, but it still cannot find about those missing files. And the difference is huge (282 GB). I've already cleaned the Recycle bin as well.    What I am missing here and how do I identify those missing spaces?  [UPDATE]: I used  to help identify and it seems to find some gigantic files, of which filename is quite weird. Anyone knows what this is and is it safe to delete?

I need an app that tells about file &amp; folder sizes, like what is the biggest file and/or folder on my hard disk, sort this detail from biggest file and/or folder to the smallest &amp; vice versa, also able to tell me about this detail based on the folder that I have chosen.

Every time I create new folder in windows explorer I don't need it to be named New Folder. I need current date and time as folder name. For example 13:41 16.12.2012.   And, lets say, I'm too lazy to watch at the time and change folder name manually every time I create folder.   Is there any addon/extension/widget/alternative for windows7 explorer which handle some folder_created_event or something else and change it's name when folder is created?

I have a folder that starts with a dot . but am unable to display it in Finder. How can I say that for folder x, Finder should also display hidden files/folders?

As you can see below, there is so much difference between the Size and Size on disk fields in my folder. Why is that?    I know that Size on disk should be a little more than Size because of allocation units in Windows, but why that much of a difference? Could it be because of the large number of files?  BTW, this folder is on my Android phone’s SD card. Inside this, my maps app stores its cached maps and the app gets its map from Google Maps.

I like the folder-tree behavior of Windows XP, that is, clicking on any folder on the left pane will automatically expand the folder-tree. Unfortunately this is not how Explorer works in Windows 7.  Does anyone know how I can get Windows 7’s Explorer to behave like the one in XP?

Call me crazy, but I'm sure I remember this capability existing in previous versions of Windows.  In Windows 7, we can have file extensions Off... or On.  Pick one.  Is there some obscure switch buried in the registry to have Explorer show specific extensions, but leave the rest hidden?  In my case, I'd like to always show extensions for text files (*.txt, *.csv, *.tdt), because I frequently have to handle flat files which may come in with a .txt extension where I need it to be .csv, for example.  I'd rather not have extensions on all the time, it's just clutter for almost all files.

Is there a way to sort folders and files by their name all mixed together in Windows 7?  It would be easier to understand if you .  I want my folders and files arranged like the BEFORE situation of the first screenshot.  If there is no way to do that with Windows Explorer, is there any file management programs that I should try?  I've already tried Total Commander.

Occasionally, when downloading a file in a web browser, the download progress doesn't "know" the total size of the file, or how far along in the download it is -- it just shows the speed at which it's downloading, with a total as "Unknown".  Why wouldn't the browser know the final size of some files? Where does it get this information in the first place?
