Delete Files Older Than 30 Days Batch Script (1-Click)

To fix the “Low Disk Space” error, the delete files older than 30 days batch script is the safest, software-free solution. It automatically scans your cluttered Downloads, Logs, or Backup folders and instantly removes unused files, freeing up gigabytes of storage immediately without installing heavy third-party apps like CCleaner.

Does your system’s C: drive always show up in red? If your answer is yes, it’s very important for you to understand the reason behind it. We download new PDF files, images, software, and some setups from the internet every day, but after we’re done with them, we forget to delete them. After months, these “temporary” files end up taking up gigabytes of storage, causing your PC to slow down and hang because there isn’t enough space for it to run properly.

Or in such cases, people get very worried when they see a “Low Disk Space” popup and install heavy third-party software to free up storage. But I always say, when Windows has the built-in power to automatically delete old files, why install unnecessary apps on your PC? right? These third-party softwares often show a lot of ads, consume RAM in the background, and make the system even slower.

So, we’re going to create our own smart and lightweight delete files older than 30 days batch script. The benefits of this custom script are very clear, such as:

• 100% Free & Fast: No installation is required, and cleaning starts with a single click.
• Zero Background Process: It doesn’t consume any RAM because it only runs when you choose to run it.
• Fully Safe & Transparent: You decide which specific folder to clean, so there’s no risk of deleting any important files.

Line-by-Line Code Breakdown (How does it work?)

I have explained each line of this code here so that you have no doubts about the security. Let’s understand how this delete files older than x days cmd script works perfectly. We’ve used the logic of Windows’ most powerful command, ForFiles, in this. If you want to read its official server-level documentation, you can check the Microsoft ForFiles documentation.

• set “target_folder=...”: Here we set a variable. The script focuses only on this location.
• ForFiles /p: This function directs the tool to the exact folder path you provide.
• /s: This is the subdirectory command. It allows you to automatically check subfolders within the main folder.
• /d -%days%: This is the masterstroke of this script! It successfully applies the forfiles logic to delete files older than 30 days, so only those files that are exactly 30 days old are filtered. New files remain safe.
• /c “cmd /c del /q @file”: The execute (/c) command silently (/q) and permanently deletes the old files that are filtered out.

Yes, it's 100% safe.

How to Set Up the Batch Script for Your Folders?

Friends, since everyone's PC has different folders they want to clean, the most important step before running this script is to add your specific folder path to it. This can become a perfect batch script to clear the Downloads folder if you set it up correctly. To set it up, carefully follow the simple steps given below:

• Step 1: First, extract the downloaded ZIP file to your Desktop. To do this, right-click on the ZIP file and click “Extract All” or “Extract Here.”
• Step 2: After the folder is extracted, right-click on the Auto-Delete.bat file inside it and select “Edit with Notepad”. This will open the batch file directly in your Notepad.
• Step 3 (Most Important): Look carefully inside the code where it says “set ”target_folder=C:\Users\YourUsername\Downloads“”. Delete the old path from there and copy-paste the path of the folder you want to clean up. For example: set “target_folder=D:\CCTV-Backups” or E:\LogFiles.

• Step 4: If you want only files that are 7 or 10 days old to be deleted instead of 30 days old, you can easily customize it. To do this, simply change the “days=30” in the code to “days=7”.
• Step 5: After making the changes, press Ctrl + S on your keyboard to save the file and close Notepad.

After that, whenever your folder is full, just double-click this BAT file. A black screen will appear, and in a fraction of a second, your GBs of space will be freed up.
