How to ignore file in Git / Sourcetree?

Git is the most popular version control system(VCS) used by developers. Sourcetree is a free Git client for Mac and Windows systems. Every developer that used Sourcetree/Git faces the issue while doing operations like pull, push or commit. The reason behind this is that it keeps unnecessary files that are either generated by compiler or Developer Tools you use. For example .dll, .sln, .cs, .java, .vs, .vscode, .log, .rar .zip, .txt, etc.


Sourcetree uses a .gitignore file to know the list of files to be ignored and those files will not show in Sourcetree. To ignore files in Git repository, First, we need to create .gitignore file inside the repository. There are several ways to specify the ignore pattern inside the .gitignore file.

1. Ignore specific file using .gitignore in Git/Sourcetree

For example, we want to ignore the file named Readme.txt then just write ReadMe.txt in .gitignore file. This matches the exact file name on the specified path and removes it from showing inside repository difference.

2. Ignore folder using .gitignore in Git/Sourcetree

There is a pattern to ignore the whole folder and all files inside it. For example, we want to ignore the bin folder with all files inside it, then just write "bin/" inside the .gitignore file.

3. Ignore files with extension using .gitignore in Git/Sourcetree

For example, we want to ignore all .dll files, then just write "*.dll" inside the .gitignore file.

Note: If files are already committed in Git repository then even after creating .gitignore file it won't remove from repository. For that, We will have to untrack the files first. If we want every developer to follow the same pattern of ignoring files, then we will have to commit a .gitignore file to the repository.

How to ignore file in Sourcetree/Git without committing .gitignore file

Sometimes it happens that we keep some files inside the repository folder which are not committed in the repository, Those files/folder are needed just to support framework/build to get succeed. In that case, we might want to ignore those bunch of files from the repository and we also don't want to commit .gitignore file to the repository.

Below is the solution for those cases.

a. Create any text file outside the repository folder, we can name it anything. For example ".gitignore_global.txt".

Git/Sourcetree Global ignore list

b. Go to Sourcetree, Navigate to Tools -> Options -> Git. From the "Global Ignore List" option, browse the file created.

# files ending in .cache can be ignored
# but keep track of directories ending in .cache

# Others

# Since there are multiple workflows, uncomment next line to ignore bower_components
# (
