How to find a photo when you don't know which drive it's on

The short answer

To find photos on an external hard drive that's connected, search it with Finder on a Mac or File Explorer on Windows, filtered to images. If you don't know which drive holds the photo, those tools can't help much: they search the drives that are connected, so a drive in a drawer won't show up.

A catalog fixes that. CachePix catalogs the photos on your drives, then lets you search them by filename, people, keywords and caption with the drives unplugged, on your computer or your phone. On Mac, CachePix records which drive each photo is on.

Find photos on an external hard drive that's plugged in

Start here when you know which drive to check.

On a Mac: find photos with Finder and Spotlight

1. Connect the drive, open a Finder window, and click the drive under Locations in the sidebar.
2. Press Command-F. In the bar under the toolbar, choose the drive's name instead of This Mac.
3. Set the Kind menu to Image. The Add button (+) adds criteria such as Name or Created date.
4. Click Save to keep it as a Smart Folder.

Spotlight (Command-Space bar) finds files by name too. Both search the drives that are connected, so a drive in a drawer won't show up.

On Windows: search a hard drive for photos with File Explorer

1. Connect the drive, open File Explorer, and select the drive under This PC.
2. Type part of the filename in the search box at the top right. It searches the folder you're in and the folders inside it.
3. To list only photos, type kind:=picture, or use Search options to filter by kind or date modified.
4. To search several connected drives at once, search from This PC. Microsoft calls that search "slow but in-depth".

Why filenames and file dates fall short

Camera filenames such as IMG_4821.JPG say nothing about who or where, and the same name can turn up on several drives. File dates mislead too, since copying or editing a file can change them. The capture date sits in the photo's EXIF data (File Explorer calls it Date taken). Clear folder names help, so organize photos on an external hard drive as you go.

Not sure where your photos are stored?

On a Mac, start with the Pictures folder in your home folder. On Windows, check Pictures, then search This PC with kind:=picture.

Finding pictures on an old hard drive

Connect it and follow the same steps. To show all pictures on the hard drive, search from the drive's top level with Kind set to Image on a Mac, or type kind:=picture in File Explorer. If the drive doesn't show up or the photos won't open, see what to check when you can't view photos on an external hard drive.

Search by what's in the photo's metadata

You remember a photo by who was in it or where it was taken, rarely by its filename. That information can live inside the file:

• IPTC and XMP fields hold people, keywords, caption, headline, city, event and more. The IPTC Photo Metadata Standard defines them. Photo apps can save them inside the file or, for RAW files, in a sidecar next to it (DSC_0193.xmp beside DSC_0193.NEF).
• EXIF data comes from the camera: capture date, camera model, lens and sometimes GPS.

Finder can search some metadata too: Apple's guide shows how to add attributes from Other in the criteria menu, or type searches such as keyword: or title:. But like File Explorer, it searches the drives that are connected. A photo catalog keeps the metadata searchable after you unplug the drive.

CachePix reads 12 IPTC and XMP fields (people, keywords, caption, headline, title, city, state, sublocation, creator, event, category and supplemental categories), including from RAW sidecars, and takes the capture date from EXIF DateTimeOriginal.

No metadata yet? Add people, keywords or a caption in an app that saves them to the files or their sidecars, such as Photo Mechanic or Lightroom Classic. Then connect the drive and run Sync Search Metadata in CachePix. It re-reads only the files whose metadata changed. If a change doesn't show, use its Re-read every photo option.

CachePix has no facial recognition, face detection or AI tagging. People names come from metadata in your files, or names you type in CachePix. More on how to search by keywords, captions and names.

Catalog your drives once, search them anytime

CachePix is a photo catalog app for Mac and Windows. It catalogs the photos on your drives, then syncs a searchable catalog to free iPhone and Android companion apps, so you can browse your archive with the drives unplugged. Your photos never go to the cloud.

Set it up

1. Install and sign in on your Mac or Windows computer with the code we email you.
2. Catalog a drive. Connect it, open Drives & Folders, choose Catalog a Folder… and pick the drive or a folder on it. CachePix first samples about 24 photos to estimate the disk space previews will take.
3. Repeat, then unplug. CachePix keeps a 512px thumbnail and an HD preview of each cataloged JPEG, PNG, WebP and RAW photo on your computer.

Search

• One box ("Search filename, person, keyword…") matches part of a word, ignores case and looks in 13 fields: filename, people, keywords, caption, headline, title, city, state, sublocation, creator, event, category and supplemental categories.
• Words combine. "Maria Lisbon" finds photos matching a person and a city at once.
• Narrow and save. On Mac, limit a search to one drive or folder. The star saves a search to the Library sidebar with a live photo count.

Results run newest capture date first, undated photos last, 200 to a page.

See which drive it's on

On Mac, each photo keeps a record of the drive and folder it came from, and a green or gray dot shows each drive's status. On Mac, CachePix tracks each drive by its volume ID, so a renamed drive re-links the next time you connect it. Identical copies on different drives become one photo with each location listed. Edited or re-saved copies stay separate.

Found it? Export Preview… saves the HD preview, metadata embedded, with the drive unplugged. On Mac, plug the drive in for Copy Full-Resolution… or Reveal in Finder.

Other disk catalog apps

Disk catalog apps also search drives that aren't connected, and each does things CachePix doesn't. As of October 2026:

• NeoFinder (Mac) lets you browse and search a cataloged drive's contents on your Mac without the drive connected. According to its website, it catalogs and searches EXIF, IPTC and XMP metadata. It also catalogs video and has a companion app for iPhone and iPad.
• DriveVault (Mac), according to its website and Mac App Store listing, lets you search and browse a scanned drive on your Mac after the drive is unplugged. It reads and searches photo EXIF data (camera, lens, ISO, date taken) and creates low-resolution offline previews of images and videos.
• WinCatalog (Windows), according to its website, lets you search its catalog on your Windows PC even when the cataloged drives are not connected, and stored photo thumbnails stay viewable. It reads EXIF data, including GPS location, and catalogs video files with a thumbnail.

Find it from your phone

Pair once: in Drives & Folders, open Pair Phone…, click Turn On, and scan the QR code with the CachePix app. The catalog syncs one way, from your computer to your phone, over your local network.

• Search ("Name, keyword, or filename") covers filenames, people, keywords and IPTC captions. All your words must match.
• Filters for Person, Keyword, Drive and Year, plus Favorites only, work together: a photo must match each one you set.
• The Info sheet lists the filename, capture date, caption, people, keywords and drive, so you know which drive to plug in.
• Away from home. Browse and search your catalog with the drives unplugged and the computer at home. CachePix checks your plan online at least once every 14 days.

Android shows up to 500 results per search. The apps need iOS 18 or later, or Android 9 or later. Here's how to view external hard drive photos on your phone, or meet the CachePix phone app.

What a catalog can't find yet

CachePix 0.2.1 has gaps worth knowing:

• Video, GIF and BMP files aren't cataloged, and Live Photo motion is ignored.
• HEIC and TIFF. HEIC and TIFF photos are cataloged and searchable, and previews for them are coming on Mac. Until then the tile shows only the filename, and the phone has no image for them.
• Camera, lens and GPS data aren't read, and there's no map. Place search uses the IPTC City, State and Sublocation text.
• Dates. There's no date search in the desktop app yet, and the phone filters by year.
• Ratings and labels set in other apps aren't read.

Need camera, GPS or video data now? According to their makers, NeoFinder searches EXIF metadata, DriveVault searches the camera, lens, ISO and date taken in EXIF data, WinCatalog searches photo GPS locations, and all three catalog video.
