ComfyUI Node: JDCN_AnyFileSelector

JDCN_AnyFileSelector:

The JDCN_AnyFileSelector node is designed to help you select a specific file from a list of file paths based on an index and a change operation. This node is particularly useful when you have a collection of files and need to dynamically select one for further processing. By providing a list of file paths, an index, and a change operation, the node allows you to either pick a fixed file, increment the selection, or decrement it. This functionality is essential for workflows that require sequential or specific file access, making it easier to manage and automate file selection tasks.

JDCN_AnyFileSelector Input Parameters:

PathList

PathList is a required input parameter that expects a list of file paths in string format. This list serves as the source from which a specific file will be selected. The accuracy and completeness of this list are crucial for the node to function correctly, as it directly impacts the file selection process.

Index

Index is an integer input parameter with a default value of 1, and it ranges from a minimum of 1 to a maximum of 9999. This parameter determines the position in the PathList from which the file will be selected. The index is 1-based, meaning an index of 1 corresponds to the first file in the list. Adjusting this value allows you to select different files from the list.

Change

Change is a required input parameter that offers three options: fixed, increment, and decrement. This parameter dictates how the index should be modified before selecting the file. The fixed option uses the index as is, increment increases the index by one, and decrement decreases the index by one. This flexibility allows for dynamic file selection based on your workflow needs.

JDCN_AnyFileSelector Output Parameters:

out

out is the output parameter that returns the selected file path as a string. This output is crucial as it provides the specific file path selected based on the input parameters, which can then be used in subsequent nodes or processes. The returned file path is the one located at the specified index in the PathList.

JDCN_AnyFileSelector Usage Tips:

• Ensure that the PathList is correctly populated with valid file paths to avoid errors during file selection.
• Use the Index parameter to directly access a specific file in the list, especially useful when you know the exact position of the file you need.
• Utilize the Change parameter to automate file selection in sequential workflows, such as processing files in order or iterating through a list of files.

JDCN_AnyFileSelector Common Errors and Solutions:

Error in List Variable

• Explanation: This error occurs when the PathList is empty or the Index is out of the valid range.
• Solution: Ensure that the PathList contains valid file paths and that the Index is within the range of the list length. Double-check the list and index values to correct any discrepancies.
