How to Find a File Containing a String in Its Name Using Python

Finding files by their names can sometimes be a daunting task, especially if you have a large directory filled with files and only partial names to work with. Whether you are dealing with a batch of images, documents, or any other type of file, knowing how to automate this process with Python can save you time and effort.

In this guide, we'll walk you through the steps required to search for files within a specific folder based on partial names stored in an Excel sheet. The end goal is to locate these files and organize them into a new folder for easy access. Let's dive into the details!

Understanding the Problem

Suppose you have an Excel sheet that contains a list of partial file names. You also have a folder full of JPG files, and your task is to identify which of these files match the strings provided in your Excel sheet. Manual searching can be tedious, but with Python's powerful libraries, we can efficiently automate this task.

Step-by-Step Solution

1. Setting Up Your Environment

Before you start coding, ensure you have Python installed on your computer. You'll also need the following libraries:

os for interacting with the operating system and file directories

pandas to handle Excel files (if you're working with xlsx files)

If you don't have Pandas installed yet, you can do so via pip:

2. Import Required Libraries

Here’s how you can set up your Python script to import the necessary libraries:

3. Read the Excel File

Next, you'll want to read the file names from the Excel sheet. Assuming you have an Excel file named filenames.xlsx with the names listed in the first column:

4. Search for Matching Files in the Directory

Now, you’ll implement the loop to search through each file in your specified directory. You need to check if the partial names from the Excel sheet exist in any of the file names in the folder:

5. Save the Matched Files to a New Folder

Once you have the list of matched files, the next step is to move or copy them to a new directory. Here's an example of how you can copy the files:

Conclusion

By following these steps, you can effectively search for files based on partial names stored in an Excel sheet using Python. This method is efficient, reduces manual effort, and helps keep your files organized.
