How to Exclude Files When Extracting with Unrar

Extracting RAR archives using the command-line utility unrar often involves files you do not need, such as text documents, system files, or large media assets. You can configure unrar to selectively bypass these files during extraction by using the -x exclusion switch. This guide explains how to exclude specific file names, wildcards, directories, and file lists to streamline your extraction process.

The Basic Exclusion Switch (`-x`)

To exclude a file or a pattern during extraction, append the -x switch to your unrar command followed immediately (or with a space) by the file name or mask.

Basic syntax:

unrar x -x<pattern> archive.rar

Note: Use the x command to preserve the archive's internal directory structure, or e to extract everything into a single flat directory.

Exclude a Specific File

To extract an archive while ignoring a specific file, provide the full file name to the -x switch:

unrar x -xreadme.txt archive.rar

Exclude File Types Using Wildcards

You can use standard wildcards (* and ?) to filter out entire formats or file types. To avoid shell expansion issues in Linux or macOS terminal environments, always wrap wildcard arguments in quotes.

To skip all .txt files:

unrar x -x"*.txt" archive.rar

To skip multiple distinct file types, append multiple -x switches:

unrar x -x"*.nfo" -x"*.txt" -x"*.exe" archive.rar

Exclude Entire Folders

To prevent an entire directory and its contents from extracting, add wildcard slashes to indicate the path structure:

unrar x -x"*/sample/*" archive.rar

On Windows environments, use backslashes instead:

unrar x -x*\sample\* archive.rar

Exclude Files Using an External List File

When dealing with a long list of exclusions, you can write the patterns into a plain text file (one pattern per line) and instruct unrar to read it by combining -x with @.

Create a file named exclude.txt:
```
*.nfo
*.sfv
*.txt
*/temp/*
```
Run unrar referencing the exclusion list:
```
unrar x -x@exclude.txt archive.rar
```
