Where sparse-file is the file name, and the number at the end is the file size in bytes. extfs.d: /usr/local/Cellar/midnight-commander/4.8.26/libexec/mc/extfs.d/. Go to the folder where you need to create a file and type the following:įsutil file createnew sparse-file 1000000000 Copy When you type a command in the panel then switch to subshell the typed command. 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). The commands in our list are everyday commands that all users should know, and cover a wide array of tasks, such as file system navigation, process monitoring, file reading and manipulation, networking, user management, and package installation. 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. The space for storing data is allocated automatically as more and more information is written. The biggest advantage of sparse files is that users can create very large files which take very little disk space.

If you have a single drive in the computer and you just connected a USB drive to it, there’s a good chance the exFAT file system will be /dev/sdb1 instead. This is the first partition (1) on the third device (c). In the example below, the device is located at /dev/sdc1. 🐧🍏 Sparse Files in Windows, Linux and MacOS, File Systems NTFS, REFS, Ext3, Ext4, BTRFS and APFS 🐧🍏 Pros and cons Next, run the following command to mount the device.
