Managing files and folders efficiently is essential for keeping your Windows computer organized, especially when dealing with large amounts of data. Whether you are trying to locate large folders consuming storage space, sort directories by modification date, clean up old files, or simply improve file management, Windows 11 and Windows 10 offer several ways to sort folders by size, date, or month.
Unfortunately, Windows File Explorer does not always make folder size sorting as straightforward as users expect. While files can be sorted easily, folders often require additional methods, settings changes, or third-party tools to display accurate size information. Sorting by month, however, is easier and can help users quickly identify recently modified or older directories.
Understanding how to sort folders properly can save time, improve system organization, and help with storage optimization. This guide explains all available methods, including File Explorer settings, search filters, Group By options, folder size tools, PowerShell commands, and third-party software for deeper folder analysis.
Whether you are cleaning up your drive, managing work files, or organizing backups, this comprehensive tutorial will help you sort folders by size or month effectively in Windows 11 and Windows 10.
Why Sorting Folders By Size Or Month Matters
Sorting folders can be useful for many reasons:
- Finding storage-heavy directories
- Cleaning disk space
- Organizing old projects
- Locating recently modified folders
- Managing downloads
- Improving backup planning
- Tracking file growth over time
Common Use Cases:
- Identifying folders filling SSD or HDD space

- Deleting old backups
- Organizing media collections
- Monitoring software installation sizes
Understanding File Explorer Sorting Limitations
Windows File Explorer allows:
- Sorting files by size
- Sorting by date modified
- Sorting by type
- Sorting by name
However:
Folder size is not displayed automatically because Windows does not calculate folder sizes in real-time due to performance concerns.
This means:
- Folder size column is unavailable by default
- Extra tools may be needed
- Folder month sorting is easier than folder size sorting
Method 1: Sort Folders By Month Using File Explorer
Sorting folders by date or month is simple.
Step 1: Open File Explorer
- Press Windows + E
Step 2: Navigate To Desired Directory
For example:
- Documents
- Downloads

- External drives
Step 3: Switch To Details View
- Click View

Step 4: Use Date Modified Column
- Click Date modified
Result:
Folders and files will sort by:

Method 2: Use Search Filters To Sort By Month
Windows Search can narrow results.
Examples:

This Helps:
- Find recent folders
