What you need before you start

Seeing PSD and AI files in File Explorer takes a little preparation. Work through this list first.

A Windows PC you can change. Some add-ons need permission to install. If your work machine is locked down, check whether a tool offers an installation option that suits your setup.
The exact file types you use. Write down the extensions in your folders, such as PSD and AI files. Each tool lists the formats it handles, and you want yours on that list.
Your Windows version and chip type. Check whether you run Windows 11 and whether the processor is x64 or ARM64, since installers can differ by chip.
Your kind of use. Personal projects and paid client work can have different licence terms. Decide which applies before you install anything.
A test folder. Pick a folder with a few design files so you can check the preview result.
A backup of anything important. Keep original design files protected before adding new software.

Close open File Explorer windows so you can restart them cleanly after installation.

Step by step

These steps are general for thumbnail or preview tools, but each tool's own page may add its own installation steps.

Open your test folder and note the current state. Switch the view to Large icons or Extra large icons from the View menu. If PSD or AI files show generic icons, previews are missing for those types.
Check that thumbnails are allowed. Open Folder Options and make sure the setting that always shows icons instead of thumbnails is not selected. This setting hides thumbnails for every file type.
Pick a preview tool. Compare the formats each one lists against your own file extensions. Also read its licence terms for personal or commercial use.
Download from the maker's own page. Choose an installer that matches your computer. If you cannot install software, check whether a portable option is available.
Install it and restart File Explorer. Signing out and back in, or restarting the PC, can also refresh Explorer.
Reopen the test folder. Check PSD and AI files to see whether previews appear. Large folders may take longer than small folders.
Clear the thumbnail cache if icons stay plain. Use Windows tools that manage the thumbnail cache, then reopen the folder.
Check different design files. A file saved from a different version of a design application can behave differently, so test the files used in regular work.
Check where the files live. If files are stored in synced folders, confirm that previews appear there too.
Use the preview for sorting, not final decisions. Open the design file in the editing application when exact appearance matters.

Tools that can do it

Facts are published here for only one tool, so the comparison is short. For any other option, such as a codec pack or another thumbnail add-on, check its own page for the design formats it names, its Windows support, its licence and whether it needs administrator rights.

### SageThumbs 2K

SageThumbs 2K is made by the team that publishes this site. It adds File Explorer thumbnails for 363 file types that Windows can't render natively, including camera RAW, Photoshop PSD, HEIC/AVIF, and video. ^[1] It pulls an embedded preview directly out of design and CAD files such as Photoshop, Affinity, AutoCAD DWG, and CorelDRAW with no rendering needed. ^[1] Check the format list for AI files before choosing a tool for those files. It runs on Windows 11, with separate installers for x64 and ARM64. ^[1] You can use a portable zip that needs no admin rights. ^[1]

For design files, check details such as colour handling and metadata, and test the result with real files. Images carrying an embedded ICC profile or wide-gamut tag are converted into sRGB before display. ^[1] It adds image dimensions and other file details to Explorer areas for formats Windows can't read itself. ^[1] SageThumbs 2K says a corrupt or malicious file cannot crash File Explorer, because it runs separately from Explorer and reads files in a sandbox. ^[1]

On cost, it is free for personal, noncommercial use under the PolyForm Noncommercial License 1.0.0. ^[1] Commercial use needs a per-installation licence: US$2.99 a month, or US$49 once for a perpetual licence with 12 months of updates. ^[1] Business installs get a 7-day evaluation with every feature, after which thumbnails and previews stop until a licence key is entered. ^[1]

Common mistakes to avoid

Skipping the Folder Options check. If Explorer is set to show icons only, no add-on can bring thumbnails back. Check this setting first.
Installing the wrong build. Match the installer to your chip type. A mismatched build can stop a tool from working.
Ignoring the licence. Personal use terms do not automatically cover paid client work. Read the terms before using a tool for studio projects.
Testing with only one file. Design files can be saved in different ways. Test files from the applications and workflows you use.
Trusting thumbnail colour for editing. A thumbnail is a quick guide for sorting. Judge colour and detail in your editing program.
Forgetting synced folders. Check how a tool treats files in cloud folders before moving a design archive there.
Installing several thumbnail tools at once. Two tools handling the same format can interfere with each other. Remove one before trying another.

Why does File Explorer show plain icons for PSD and AI files?
