5 Proven Ways To Free Up Space On Raspian

Are you running out of storage space on your Raspberry Pi? Don’t worry, you’re not alone! Many Raspberry Pi users find themselves in this situation at some point. The good news is that there are a few things you can do to free up space and get your Pi running smoothly again. In this article, we will take a look at some of the most effective ways to free up space on a Raspberry Pi running Raspbian.

One of the simplest ways to free up space on your Raspberry Pi is to remove any unnecessary files or programs. This includes things like old downloads, temporary files, and programs that you no longer use. You can use the following commands to find and delete unnecessary files:

Uninstall Unnecessary Software

One of the most effective ways to free up space on your Raspberry Pi running Raspian is to uninstall any software that you no longer need or use. This can be done through the command line or through the graphical user interface (GUI).

To uninstall a program through the command line, open a terminal window and type the following command:

sudo apt-get remove [package name]

For example, to uninstall the LibreOffice suite, you would type the following command:

sudo apt-get remove libreoffice

To uninstall a program through the GUI, open the Applications menu and click on “System Tools” > “Synaptic Package Manager”. In the Synaptic Package Manager, search for the program that you want to uninstall and click on the “Uninstall” button.

Here is a table summarizing the steps for uninstalling unnecessary software:

Method	Steps
Command line	Open a terminal window and type the following command: `sudo apt-get remove [package name]`
GUI	1. Open the Applications menu and click on “System Tools” > “Synaptic Package Manager”. 2. Search for the program that you want to uninstall and click on the “Uninstall” button.

Remove Unused Files and Packages

Raspbian, like any other operating system, can accumulate unneeded files and packages over time. These files can take up valuable storage space on your Raspberry Pi, slowing down your system and making it harder to find the files you need.

Remove Unused Files

To remove unused files, you can use the du and df commands. The du command will show you how much space each file and directory is using, while the df command will show you how much space is available on each of your partitions.

Once you’ve identified the files that you no longer need, you can delete them using the rm command. For example, to delete the file “unused_file.txt”, you would use the following command:

rm unused_file.txt

Remove Unused Packages

In most cases, you should not manually remove packages that you no longer need. The vast majority of packages are small, and keeping them installed on your system is not a problem. However, if you have a package that is unusually large or is no longer used, you can remove it using the apt-get command.

To remove a package, you would use the following command:

sudo apt-get remove package_name

For example, to remove the package “unused_package”, you would use the following command:

sudo apt-get remove unused_package

Once you have removed the unused package, you can free up even more space by running the following command:

sudo apt-get autoclean sudo apt-get clean

These commands will remove all of the downloaded package files and their dependencies, freeing up more space on your Raspberry Pi.

Command	Description
`du`	List the disk usage of files and directories
`df`	List the disk usage of file systems
`rm`	Delete files
`apt-get remove`	Remove a package
`apt-get autoclean`	Remove all downloaded package files
`apt-get clean`	Remove all downloaded package files and their dependencies

Clean Up Log Files

Log files can accumulate over time and take up a significant amount of space on your Raspbian system. To clean up log files, you can use the following steps:

Open the terminal and type the following command:

sudo journalctl --vacuum-time=1d

This command will delete all log files that are older than 1 day.

If you want to delete all log files, you can use the following command:

sudo journalctl --vacuum-time=all

This command will delete all log files, regardless of their age.

You can also manually delete log files by using the following command:

sudo rm /var/log/*.log

This command will delete all log files in the /var/log directory.

Please note that deleting log files can make it difficult to troubleshoot problems. If you are not sure whether or not you need a particular log file, it is best to leave it alone.

Compress Operating System Files

Compressing operating system files can significantly reduce their size, freeing up valuable storage space. Here are some methods to compress these files:

1. Use the “raspi-config” Tool

Run the “raspi-config” command and navigate to “Advanced Options > Filesystem and Memory”. Select the “Compress Operating System Files” option and hit Enter. Follow the on-screen instructions to complete the compression process.

2. Use the “compress-raspbian” Script

Download the “compress-raspbian” script from GitHub and run it with sudo privileges. This script automates the compression process, providing a convenient way to reduce file sizes.

3. Use the “dpkg-repack” Utility

The “dpkg-repack” utility allows you to recompress individual packages. To use it, identify the packages taking up the most space using the “dpkg-query -Wf ‘${Installed-Size} ${Package}\n’ | sort -nr” command. Then, run “sudo dpkg-repack –compress ” to recompress the selected packages.

4. Use the “squashfs” File System

The SquashFS file system can be used to create a compressed image of the operating system. To do this, follow these steps:

Download and install SquashFS.
Create a new folder and copy the contents of the root filesystem into it.
Run “mksquashfs .sqshfs” to create the compressed image.
Unpack the compressed image using “unsquashfs .sqshfs”
Replace the original root filesystem with the unpacked image.

Advantage	Disadvantage
Significant space savings	Slower boot times
Data integrity is preserved	Requires more computational resources to unpack

Use a File Cleaner Tool

File cleaner tools are specialized software programs designed to identify and remove unnecessary files from your Raspberry Pi’s storage. These tools can scan through your system and identify files that are no longer needed, such as temporary files, cache files, log files, and duplicate files. By removing these files, you can free up significant amounts of space on your Raspberry Pi.

There are several different file cleaner tools available for Raspberry Pi, including:

Tool	Features
BleachBit	Comprehensive cleaning tool with advanced options
SD Maid	User-friendly app with automatic cleaning schedules
Disk Usage Analyzer	Visual tool that helps you identify large files and directories
System Cleaner	Lightweight tool that focuses on removing system-generated junk files

Choosing a File Cleaner Tool

When choosing a file cleaner tool, it’s important to consider the following factors:

* Features: Some file cleaner tools offer more advanced features than others, such as automatic cleaning, detailed scanning options, and the ability to remove specific file types.
* Ease of Use: Look for a tool that has a user-friendly interface and is easy to navigate.
* Compatibility: Make sure the file cleaner tool is compatible with your Raspberry Pi model and version of Raspian.
* Reviews: Read online reviews from other users to get an idea of the tool’s effectiveness and reliability.

Delete Caches and Temporary Files

The temporary files and caches can take up a lot of space on your Raspberry Pi. You can delete them to free up some space.

1. Delete Package Cache

The package cache can be deleted using the following command:

sudo apt-get clean

2. Delete apt Cache

The apt cache can be deleted using the following command:

sudo apt-get autoclean

3. Delete Temporary Files

The temporary files can be deleted using the following command:

sudo rm -rf /tmp/*

4. Delete Log Files

The log files can be deleted using the following command:

sudo rm -rf /var/log/*

5. Delete Thumbnails

The thumbnails can be deleted using the following command:

sudo rm -rf /var/cache/thumbnails/*

6. Delete Old Kernels

The old kernels can be deleted using the following command:

First, list the installed kernels:

dpkg --list 'linux-*'

Then, remove the old kernels:

sudo apt-get purge 'linux-*' --auto-remove

Archive Unused Data

Archiving unused data is a great way to free up space on your Raspberry Pi. You can archive data that you don’t need to access frequently, such as old backups, logs, or media files. To archive data, you can use the tar command. For example, to archive a directory called old-backups, you would run the following command:

tar -cvf old-backups.tar old-backups

This will create a tar archive called old-backups.tar in the current directory. You can then move the archive to another location, such as an external hard drive, to free up space on your Raspberry Pi.

In addition to using the tar command, you can also use a graphical tool to archive data. One popular tool is PeaZip. PeaZip is a free and open-source file archiver that can be used to create and extract archives in a variety of formats. To archive data using PeaZip, simply drag and drop the files or directories that you want to archive into the PeaZip window. Then, click on the “Add” button to create an archive.

Once you have archived your unused data, you can delete the original files to free up space on your Raspberry Pi. To delete a file or directory, you can use the rm command. For example, to delete the old-backups directory, you would run the following command:

rm -rf old-backups

Use a File System with Compression

Using a file system with compression can significantly reduce the amount of space required to store files. Several file systems support this feature, including ext4 and ext3. When using ext4, you can enable compression by mounting the partition with the compress option. For example:

sudo mount -o compress /dev/sda1 /mnt/mypartition

This will mount the partition /dev/sda1 at /mnt/mypartition with compression enabled. All files created on this partition will be compressed automatically. You can also use the e2fsck utility to compress existing files on an ext3 or ext4 partition:

sudo e2fsck -f -C 0 /dev/sda1

Here is a table summarizing the different file systems and their support for compression:

File System	Compression Support
ext4	Yes
ext3	Yes
XFS	No
NTFS	Yes

Enable Swap Space

Swap space is a portion of your hard drive that is used as virtual memory. When your system runs out of physical memory (RAM), it can move some of the less-used pages of memory to swap space, freeing up RAM for more important tasks.

Enabling swap space can improve the performance of your system, especially if you are running multiple programs or have a large number of tabs open in your browser.

To enable swap space, open a terminal window and run the following command:

“`
sudo fallocate -l 2G /swapfile
“`

This command will create a 2GB swap file at /swapfile. You can adjust the size of the swap file to suit your needs.

Once the swap file has been created, you need to activate it by running the following command:

“`
sudo mkswap /swapfile
“`

Finally, you need to add the swap file to your system’s configuration by running the following command:

“`
sudo swapon /swapfile
“`

You can now verify that swap space is enabled by running the following command:

“`
free -h
“`

Additional Notes

Here are some additional notes about enabling swap space:

The optimal size of your swap space will vary depending on the amount of RAM you have and the types of programs you run. A good rule of thumb is to make your swap space twice the size of your RAM.
Swap space can be used on any type of storage device, but it is best to use a fast storage device such as an SSD.
If you are using a Raspberry Pi, you can create a swap file on a USB drive. This can be a good way to improve the performance of your Raspberry Pi without having to buy a larger SD card.

The following table summarizes the commands used to enable swap space:

{| | | | | | |}
| sudo fallocate -l 2G /swapfile | Create a 2GB swap file |
| sudo mkswap /swapfile | Activate the swap file |
| sudo swapon /swapfile | Add the swap file to your system’s configuration |
{| | | | | | |}

Install a Light Desktop Environment

If you’re running a heavy desktop environment like GNOME or KDE, switching to a lighter one can free up a significant amount of space. Some popular lightweight desktop environments for Raspberry Pi include:

Xfce4
LXDE
LXQt
MATE
Raspberry Pi Lite

To install a light desktop environment, first remove your current one using the commands:

sudo apt-get purge [desktop-environment-package-name]

For example, to remove GNOME, use:

sudo apt-get purge gnome-shell gnome-settings-daemon

Then, install your desired light desktop environment using the commands:

sudo apt-get install [desktop-environment-package-name]

For example, to install Xfce4, use:

sudo apt-get install xfce4 xfce4-goodies

Once installed, restart your Raspberry Pi and select your new desktop environment at the login screen.

How to Free Up Space on Raspberry Pi
