How To Compress a Directory and FTP it to Windows

Ubuntu 13

In this article, we will walk you through the process of compressing a directory in Linux and then transferring it to a Windows system using FTP (File Transfer Protocol). This process is particularly useful when you need to backup, share, or transfer large amounts of data.

Compressing a Directory

There are several ways to compress a directory in Linux. We will cover four popular methods: tar with gzip, zip, p7zip, and rar.

Using tar and gzip

Tar (Tape Archive) is a popular command line tool used to create archives, while gzip (GNU zip) is used to compress them. Here’s how to use them:

  1. Open your terminal.
  2. Navigate to the directory you want to compress using the cd command.
  3. Run the following command:
tar -czvf compressed_filename.tar.gz directory_name

In this command, -c stands for create, -z for gzip compression, -v for verbose (to display the progress in the terminal), and -f for file. The compressed_filename.tar.gz is the name of the output file, and directory_name is the name of the directory you want to compress.

Using zip

Zip is another popular compression tool. Here’s how to use it:

  1. First, install the zip utility if it’s not already installed by running:
sudo apt-get install zip
  1. Navigate to the directory you want to compress.
  2. Run the following command:
zip -r compressed_filename.zip directory_name

In this command, -r stands for recursive, which means it will include all subdirectories of directory_name in the zip file.

Using p7zip

p7zip is a command line version of 7-Zip, which supports many archive formats. Here’s how to use it:

  1. First, install p7zip if it’s not already installed by running:
sudo apt-get install p7zip-full
  1. Navigate to the directory you want to compress.
  2. Run the following command:
7z a compressed_filename.7z directory_name

In this command, a stands for add, which means it will add directory_name into the compressed_filename.7z archive.

Using rar

RAR is a proprietary archive file format that supports data compression. Here’s how to use it:

  1. First, install rar if it’s not already installed by running:
sudo apt-get install rar
  1. Navigate to the directory you want to compress.
  2. Run the following command:
rar a compressed_filename.rar directory_name

In this command, a stands for add, which means it will add directory_name into the compressed_filename.rar archive.

Transferring the Compressed File to Windows via FTP

Once you have compressed your directory, the next step is to transfer the compressed file to your Windows system via FTP. Here’s how to do it:

  1. Install an FTP client on your Linux system if it’s not already installed. You can use ftp or lftp for this purpose. To install lftp, run:
sudo apt-get install lftp
  1. Connect to your FTP server by running:
lftp ftp://username:password@ftp_server_address

Replace username, password, and ftp_server_address with your FTP server’s credentials and address.

  1. Once connected, switch to binary mode by running:
set ftp:ssl-allow no
set ftp:passive-mode true
set ftp:binary yes

Binary mode is used to transfer binary files (like our compressed file) without any changes.

  1. Navigate to the directory where your compressed file is located using the cd command.
  2. Upload the compressed file to the FTP server by running:
put compressed_filename.tar.gz

Replace compressed_filename.tar.gz with the name of your compressed file.

  1. Once the transfer is complete, exit the FTP client by running:
exit
  1. On your Windows system, use an FTP client like FileZilla to download the compressed file from the FTP server.

And that’s it! You have successfully compressed a directory and transferred it to a Windows system using FTP. If you encounter any issues, make sure to check your FTP server’s settings and ensure that your FTP client is in binary mode.

What is FTP?

FTP (File Transfer Protocol) is a standard network protocol used for transferring files between a client and a server on a computer network. It allows for the easy sharing and transfer of files over the internet.

Why do I need to compress a directory before transferring it via FTP?

Compressing a directory before transferring it via FTP helps reduce the file size, making it faster to transfer and saving bandwidth. It also allows you to bundle multiple files and directories into a single compressed file for easier management and organization.

Can I compress a directory with password protection?

Yes, you can compress a directory with password protection using certain compression tools like zip and rar. These tools provide options to set a password for the compressed file, ensuring that only authorized users can access its contents.

Is FTP a secure method for transferring files?

FTP is not inherently secure as it transfers data in plain text, including usernames, passwords, and file contents. However, you can enhance the security of FTP by using secure FTP protocols like FTPS (FTP over SSL/TLS) or SFTP (SSH File Transfer Protocol), which encrypt the data during transit.

How can I extract a compressed file on a Windows system?

To extract a compressed file on a Windows system, you can use built-in tools like File Explorer or third-party software like WinRAR or 7-Zip. Simply right-click on the compressed file, select the "Extract" option, and choose the destination folder to extract the contents of the file.

Are there any size limitations when transferring files via FTP?

The size limitations for transferring files via FTP depend on various factors, including the FTP server’s configuration, available storage space, and network limitations. However, FTP itself does not impose any specific file size limits, allowing you to transfer files of any size as long as the server and network can handle it.

Can I automate the compression and FTP transfer process?

Yes, you can automate the compression and FTP transfer process by creating scripts or using automation tools like cron jobs in Linux. These scripts can be scheduled to run at specific times or triggered by events, making it convenient to perform regular backups or transfers without manual intervention.
