Folder Sizes – Copy, Cut, Paste, Delete, and Rename

In past releases of Folder Size, you could only delete files and folders. While this was sufficient in order to free up space, having Copy, Cut, Paste, and Rename features make it easier to reorganize files and folders. You can now use all those new features in order to rearrange folders and files.

Having Copy, Cut, and Paste options is great, but we have taken those features a step further. You can now Copy, Cut, and Paste from and to Windows Explorer. This means that you can now go to Windows Explorer and use the context menu to Copy an item and then go to Folder Size and use the context menu to paste it there. This is so flexible and convenient that, using Folder Size is like having a Windows Explorer with folder sizes.

Shell Context Menu in Folder Size

The shell context menu is the menu that is displayed when you right-click an item or empty space in Windows Explorer. We have integrated the entire Windows Explorer context menu in the latest version of Folder Size. You can easily understand that this will let you use all the features that you have inside Windows Explorer in Folder Size.

For example, you can use the shell context menu to create new folders and then copy or move items in them. You can use the third-party applications that have entries in it to manipulate files and folders. Such tools can extract or create archives, scan files and folders for viruses, play, view, or edit files, etc. Now you have all the flexibility of Windows Explorer inside Folder Size.

Monitor File System Changes and Update Folder Sizes

Another great new feature of Folder Size is the ability to monitor the file system changes. It will update the scan results automatically. This means that if you copy, cut, rename, delete, or move files using Windows Explorer the changes will be applied to the Folder Size results immediately. You no longer have to rescan the folders if you have modified the file system outside of the application.

While this is a great feature there are certain cases in which you wouldn’t want such changes to be applied automatically. For example, if you have loaded a project file that you have saved earlier you may not want its contents to be altered. That is why we have made this feature optional. Loading a saved project will automatically disable the feature. If you want to use it on a saved project, you can simply press the toolbar button to enable it.

Disabling the option for monitoring the file system changes, disables also the shell context menu. This is just a precaution as the loaded project may contain drives, folders, and files that do not exist on the local computer at all. Invoking the context menu on such missing items may cause issues. Nevertheless, if you load a project that you have saved from the local computer, you can simply use the toolbar button to enable the shell menu.

Show Folder Sizes Instantly – Without Rescan

The new feature for monitoring the file system changes has another great benefit. If you scan your drives and keep the application running, all the changes to the file system will be updated in Folder Size automatically. This means that you have up-to-date information about all folders and file sizes at any point in your work. All you need to do is to switch to the Folder Size application and take a look at the items that you are interested in.

The best part is that this has a ZERO impact on the performance of your system. Unlike other tools that install services or shell hooks, Folder Size uses native Windows features to detect modifications to the file system.

A service is an application that has no user interface and starts when Windows is started and works in the background to do tasks. Tools that use services are slowing down your system even if you are not using them. That is because the service that they have installed is working regardless if you are using the tool or not. The service is gathering information on files and folders at all times and the application that uses the service just requests that data when started.

A shell hook can have an even worse performance impact on a system. A shell hook is similar to a service, but every file operation calls a function from the application that has installed the hook. If the hook is not developed properly it may cause huge performance issues. Another potential issue is that it may leak memory – use memory without freeing it properly. As such a hook is called for every file operation, even the smallest memory leak may deplete all the memory of the system in a short time.

Folder Size does not install services or shell hooks and you will never run into such issues.


Excessively Long File Path and Names Support

Many users are not aware of the fact that Windows has a limit of 260 characters for folder paths. This is the maximum count of characters for the folder plus the file name. Nevertheless, Windows Explorer does allow you to create longer paths. Unfortunately, they cause issues when accessed both in applications and in Windows itself.

Microsoft lifted this limit in newer Windows versions. They have not officially announced and enabled it yet though. In Windows 10 and later you can manually enable support for long paths. Nevertheless, we do not recommend using excessively long paths and file names. Folder Size supports long paths, but you may experience issues in many applications including Windows itself.
