ComfyUI Node: Get File Info 🐑

Get File Info 🐑| Get File Info 🐑:

The GetFileInfo| Get File Info 🐑 node is designed to provide detailed information about a specified file, making it a valuable tool for managing and analyzing file data within your projects. This node retrieves essential file attributes such as size, creation time, modification time, and a hash value based on a chosen algorithm. By offering these details, the node helps you understand the file's characteristics and verify its integrity, which is particularly useful for tasks involving file management, data validation, and security checks. The node's ability to compute a hash value using different algorithms like md5, sha1, or sha256 adds an extra layer of utility, allowing you to ensure the file's authenticity and detect any changes or corruption. Overall, GetFileInfo| Get File Info 🐑 serves as a comprehensive solution for obtaining and verifying file information, enhancing your workflow efficiency and data reliability.

Get File Info 🐑| Get File Info 🐑 Input Parameters:

file_path

The file_path parameter specifies the location of the file you want to analyze. It is a string that represents the relative path to the file from a base directory. This parameter is crucial as it determines which file's information will be retrieved. The default value is "input/abc", but you should provide the actual path to the file you are interested in. The accuracy of the file information depends on the correctness of this path.

hash_algorithm

The hash_algorithm parameter allows you to choose the algorithm used to compute the file's hash value. This is important for verifying the file's integrity and ensuring it has not been altered. The available options are md5, sha1, sha256, and None, with sha256 being the default choice. Selecting a hash algorithm is essential for tasks that require data validation or security checks, as it provides a unique fingerprint of the file's content.

Get File Info 🐑| Get File Info 🐑 Output Parameters:

file_info

The file_info output is a dictionary containing detailed information about the specified file. This includes the file's size, creation time, modification time, and hash value. Each piece of information serves a specific purpose: the size helps in understanding the file's storage requirements, the creation and modification times provide insights into the file's history, and the hash value is crucial for verifying the file's integrity. This comprehensive output allows you to make informed decisions based on the file's attributes.

Get File Info 🐑| Get File Info 🐑 Usage Tips:

• Ensure the file_path is correctly specified to avoid errors and ensure accurate file information retrieval.
• Choose the appropriate hash_algorithm based on your security needs; sha256 is recommended for stronger security.
• Use the file information output to verify file integrity and track changes over time, which is useful for data management and security audits.

Get File Info 🐑| Get File Info 🐑 Common Errors and Solutions:

"File not found"

• Explanation: This error occurs when the specified file_path does not point to an existing file.
• Solution: Double-check the file_path to ensure it is correct and that the file exists at the specified location.

"Unsupported hash algorithm"

• Explanation: This error arises if an invalid hash algorithm is specified.
• Solution: Ensure that the hash_algorithm is one of the supported options: md5, sha1, sha256, or None.

"Failed to compute hash"

• Explanation: This error can occur if there is an issue with reading the file or computing its hash.
• Solution: Verify that the file is accessible and not corrupted, and ensure the correct hash algorithm is selected.
