How to find recently opened or changed files

It happens to everyone. You save a file, close the program, and the next day you have no idea what you called it or which folder it went into. The good news: your computer remembers when you touched it, even if you don't remember the name.

This guide shows how to find recently modified files by date. We start with Windows, then Mac, then show the quicker way, which is asking Key.

First, know the difference between opened and changed

Your computer keeps a few different dates for each file. Two matter here:

• Date modified is the last time the file was saved with changes. This is the best clue for a document you worked on yesterday.
• Date last opened is the last time you looked at it, even if you changed nothing. This is useful for a file you only read, like a PDF someone sent you.

If you are not sure which one fits, try both. It takes a minute.

On Windows: look in Quick access first

This is the fastest check, and it often works.

1. Press Windows + E to open File Explorer. You can also click the folder icon on the taskbar.
2. Look at the Quick access section on the home screen. Microsoft says your frequently used folders and recently used files are listed there.
3. Find your file in the recent list and double-click it.

If it is not there, move on to sorting a folder by date.

On Windows: sort a folder by date modified

Use this when you have a good guess about the folder, such as Documents or Downloads.

1. Open File Explorer and click the folder you want to check.
2. Click View in the toolbar at the top and choose Details. This shows a column for each kind of information, including the date.
3. Click the heading Date modified. Click it once to sort, and click it again to flip the order.
4. Make sure the newest files are at the top. If the oldest ones are on top, click the heading once more.

On Windows: search by date

If you don't know the folder, search for the date instead of the name.

1. Open File Explorer and click a place to search, such as Documents or This PC.
2. Click the search box at the top right.
3. Type datemodified:yesterday and press Enter.

You can also try datemodified:this week or datemodified:last week. Searching all of This PC can take a while, so a smaller place is better when you can guess one.

On Mac: check Recents in Finder

1. Click the Finder icon (the blue smiling face) in the Dock.
2. In the sidebar on the left, click Recents. Apple describes this as a place for the files you have used lately.
3. Look through the list and double-click your file.

If Recents is missing from your sidebar, open the Finder menu, choose Finder › Settings › Sidebar, and tick Recents. You can also use the keyboard shortcut Shift + Command + F to jump to it.

On Mac: sort a folder by date

1. Open the folder in Finder, such as Documents or Downloads.
2. Choose View › as List, or press Command + 2.
3. Click the Date Modified column heading. Click it again to reverse the order, so the newest files come first.

Apple also lets you group files. Click the Group icon in the Finder toolbar and choose an option such as Date Last Opened. Your files are then split into headings like Today and Yesterday, which makes a day-old file easy to spot.

On Mac: use Spotlight

Press Command + Space and start typing. Results appear as you type, with the best match at the top. This works well when you remember even a word from the file name. If you remember nothing, Recents and the date columns above are the better tools.

Ask Key to find it for you

Sorting by date works, but it means clicking through folders and guessing. With Key you can just say what you remember. Key is a free assistant for Windows 10 and 11 and for Macs running macOS 11 Big Sur or newer. You can speak to it or type to it, and both give the same result.

It finds files by what is inside them, not just the name, and it reads the document to be sure it found the right one. If two files match, it asks which one you meant. Half a sentence is enough, for example "Where did that download go?" or "Find my March bill".

Key works in the real windows you already use, so you can watch a small panel show what it is doing, and you can stop it at any point. When it is done, it checks the result before it tells you.

Once you have found your file, you can ask Key to put it somewhere you will see it, like the Desktop. If your Downloads folder is the real problem, our guide on cleaning up your Downloads folder can help. And if you remember what the file said but not when you saved it, read how to find a file by what is inside it.

A few habits that save you next time

• Look at the save window. When you save, the program shows which folder it is using. Take one second to read it.
• Use clear names. A name like Electricity bill March beats Document1.
• Check Downloads. Files from email and websites usually land there, and many "lost" files are sitting in it.

Next time a file goes missing, sort by date or open Recents first. If that doesn't work, tell Key what you remember about the file.
