Go to the folder where you need to create a file and type the following:įsutil file createnew sparse-file 1000000000 Copy When the command create is performed, by default it creates a file that is not a sparse one. In Windows, sparse files are managed with the help of fsutil tool (a file system utility).
Type “cmd” in the search field and run it as Administrator. In Windows, we’ll be using the command prompt for this purpose. For example, it may generate disk overfill issues when data is copied over the existing part of the file which is marked as sparse. When the file system containing files of this specific type is low on space, it may lead to unpredictable situations.

Besides, some disk management utilities may have issues with displaying free disk space. Over time, it may result in reduced performance. For example, if the original size of a sparse file (with all of its zero bytes) is 500 MB, and the quota limit for the user account where this sparse file is created is only 400 MB, such situation generates an error, even if the actual disk space occupied by this sparse file is only 50 MB.Īs to the hard disks where such data is stored, they are also subject to fragmentation, because the file system will write data to sparse files as and when necessary. One more disadvantage is that you can’t copy or create a sparse file if its nominal size exceeds the amount of available free space (or quota restrictions applied to user accounts within the operating system). Users have to be careful when dealing with such files: a sparse file of a few megabytes may suddenly turn into a several-gigabyte monster when an application that doesn’t support this file type copies it into a directory. If a certain program cannot recognize or use such files, it will save a sparse file in its original – uncompressed – form, and there’s no advantage to talk about. However, the advantages of sparse files are limited to the applications that support them. Large sparse files are created relatively quickly because the file system doesn’t have to pre-allocate disk space for writing zeros.
Remember that your Windows Terminal hotkey is for the desktop shortcut. Press the Ctrl + Alt + W hotkey to open Windows Terminal. Then press the W keyboard key to establish a Ctrl + Alt + W hotkey.

The space for storing data is allocated automatically as more and more information is written. In this tutorial, you will learn how to format and mount disk partitions in Linux using ext4, FAT32, or NTFS file system. Right-click the Terminal desktop shortcut and select Properties. The biggest advantage of sparse files is that users can create very large files which take very little disk space. 🐧🍏 Sparse Files in Windows, Linux and MacOS, File Systems NTFS, REFS, Ext3, Ext4, BTRFS and APFS 🐧🍏 Pros and cons
