Stable Diffusion PNG Files Recovery on Windows: Recover Generated Images
Stable Diffusion PNG files recovery on Windows is straightforward because SD saves outputs to predictable local folder paths on your hard drive or SSD. When those files are deleted — whether accidentally or during cleanup — they remain in the drive's storage sectors until new data overwrites them.
This guide covers where SD outputs are stored for each major Windows installation type, what can and cannot be recovered, and a step-by-step recovery process using Ritridata.
Part 1. Stable Diffusion Output Paths on Windows
Different Stable Diffusion installations save outputs to different default directories on Windows. Knowing your output path is the first step in targeted recovery.
| SD Installation | Default Output Directory | Notes |
|---|---|---|
| AUTOMATIC1111 (WebUI) | \stable-diffusion-webui\outputs\txt2img-images\ |
Separate folders for txt2img, img2img, extras |
| ComfyUI | \ComfyUI\output\ |
Flat output folder by default |
| SD.Next / Vladmandic | \automatic\outputs\ |
Modified fork of A1111 |
| InvokeAI | \invokeai\outputs\images\ |
Date-organized subfolders |
| Stable Diffusion Forge | \stable-diffusion-webui-forge\outputs\ |
Fork of A1111; same folder structure |
| Fooocus | \Fooocus\outputs\ |
Date-organized by default |
| DiffusionBee (Mac port on Windows via VM) | VM-specific path | Uncommon on Windows |
💡 Tip: If you are unsure where your installation saves outputs, check your SD launcher's Settings tab. Most SD frontends show the output directory as a configurable field. Alternatively, generate a test image and use File Explorer to search for recently created PNG files to locate your output directory.
Part 2. Recovery by Installation Type
Different SD installations have different folder structures and may save additional metadata files alongside the PNG output. Understanding what was saved helps you identify all recoverable files.
| Installation Type | Output Files | Metadata Files | Can Metadata Be Recovered? |
|---|---|---|---|
| AUTOMATIC1111 | PNG (with embedded metadata) | Optional TXT files | Yes — metadata often embedded in PNG |
| ComfyUI | PNG, JPEG, WebP (node-dependent) | JSON workflow files | Yes — JSON recoverable separately |
| InvokeAI | PNG (with embedded metadata) | SQLite database | Database recovery is complex; focus on PNGs |
| Fooocus | PNG (with embedded metadata) | Optional log files | Yes — metadata in PNG XMP data |
| Forge | PNG (with embedded metadata) | Optional TXT files | Same as A1111 |
🗣️ r/StableDiffusion user: "I was cleaning up my C drive and accidentally deleted my entire A1111 outputs folder — about 12,000 PNGs. Ran a recovery scan and got almost all of them back. The embedded metadata in the PNGs meant I could see the prompts too."
Part 3. Why Stable Diffusion PNG Files Are Highly Recoverable on Windows
Windows NTFS file system marks deleted files as available sectors rather than immediately erasing them. PNG files are particularly well-suited to signature-based recovery because:
- PNG files start with a unique 8-byte signature:
\x89PNG\r\n\x1a\n - PNG files end with a defined IEND chunk
- The prompt metadata embedded in SD-generated PNGs (tEXt chunks) is preserved within the file data on disk
This means recovery tools can locate SD PNG files by their binary signature even when the folder structure and file names are entirely lost.
⚠️ Warning: On Windows, the Recycle Bin has a size limit. If your SD outputs folder is large (hundreds of GB), Windows may have automatically skipped the Recycle Bin entirely and deleted files permanently when you removed the folder. Always check the Recycle Bin size limit in its properties and consider increasing it to match your typical generation volume.
Part 4. Step-by-Step: Recover Deleted Stable Diffusion PNG Files
Step 1 — Check the Recycle Bin
Open the Recycle Bin on your Windows desktop. Search for .png files within it using the search bar. If your deleted outputs are here, right-click > Restore to recover them instantly.
Step 2 — Stop Generating New Images If your SD instance is running, stop it and close the interface. Continuing to generate new images writes PNG files to the output directory, which may overwrite the sectors holding your deleted generations.
Step 3 — Identify the Drive Containing Your Outputs
Locate which drive your SD outputs folder was on. For most users this is C:\ (system drive) or a secondary drive such as D:\ or E:\ if SD is installed on a secondary drive for performance reasons.
Step 4 — Install Ritridata on a Different Drive Download Ritridata and install it on a drive different from the one containing your SD outputs. If everything is on your C: drive, consider downloading the portable version of Ritridata to a USB drive first.
Step 5 — Select the Drive and Run a Scan Open Ritridata and select the drive where your SD outputs were stored. Run a Quick Scan for recently deleted files. Run a Deep Scan if Quick Scan does not locate your PNGs or if you deleted files days or weeks ago.
Step 6 — Filter for PNG Files In the scan results, apply the PNG file type filter. SD outputs are typically large PNGs — filter by file size greater than 500 KB to exclude thumbnail cache and system PNG files from the results.
💡 Tip: SD-generated PNGs often have descriptive or timestamp-based filenames. In Ritridata's results, look for filenames matching your SD installation's naming pattern (e.g.,
00001-123456789.pngfor A1111, orComfyUI_00001_for ComfyUI) to quickly identify your generations among other PNG files on the drive.
Step 7 — Save Recovered Files to a Different Drive Select your SD generation files and save them to a different drive — an external hard drive or a secondary internal drive. Do not save them back to the same drive you are recovering from.
Part 5. Recovering ComfyUI Workflow JSON Files
ComfyUI saves PNG outputs and optionally saves workflow JSON files alongside them. If you delete your ComfyUI output folder, both the image files and the workflow JSON files may be recoverable.
Workflow JSONs are small text-based files (typically 10–100 KB) that contain the complete node graph for a generation. Recovering these files means you can reproduce exact generation workflows rather than rebuilding them from memory.
JSON files have a simple text-based signature ({ at the start) and are small enough that they are less likely to be overwritten than large PNG files. Ritridata can recover JSON files alongside PNGs in the same scan by including JSON in the file type filter.
��️ r/comfyui user: "I use ComfyUI and lost my entire output folder including the JSON workflows. Got the PNGs back fine. The JSONs were also there — they're so small they were basically untouched by anything else that had been written to the drive."
Part 6. Ritridata Recommendation
Ritridata supports recovery of PNG, JPEG, WebP, and JSON files from Windows hard drives and SSDs. Its file signature scanning engine is optimized for the file types generated by all major Stable Diffusion frontends on Windows.
Recovery happens entirely on your local machine — no generated images or prompts are transmitted to any external service.

Frequently Asked Questions
Q1: Can I recover the embedded prompt metadata from a recovered PNG file? Yes. Stable Diffusion embeds generation parameters (prompt, negative prompt, sampler, steps, CFG scale, seed) as metadata in the PNG tEXt chunks. Recovered PNG files typically retain this embedded metadata intact, readable by tools like A1111's PNG Info tab or Exif.tools.
Q2: What if my SD outputs were on an SSD — is recovery still possible? Recovery on SSD is possible but the window is shorter due to TRIM. Run your recovery scan as soon as possible after deletion. On Windows, TRIM may be running in the background, so every minute counts.
Q3: Can I recover an SD output if I accidentally ran a new generation in the same output folder after deleting the old ones? New generations write new PNG files to the output directory, which may overwrite sectors holding deleted files. However, overwrite is not always total — run a deep scan and you may still recover a significant portion of the deleted outputs.
Q4: Is there a way to recover the SQLite database used by InvokeAI? SQLite databases (.db files) are recoverable using the same binary signature scanning approach. However, a recovered database may be in an inconsistent state if it was deleted mid-write. Focus on recovering the PNG files first, as they contain embedded metadata with all generation parameters.
Q5: What if I deleted SD from Windows using the uninstaller — can I still recover outputs? Most SD uninstallers ask whether to delete outputs before removal. If you skipped deleting the outputs folder, the files remain on the drive. If the uninstaller deleted the folder, run a recovery scan immediately — the files are likely still recoverable.
Q6: Can I recover files from a Stable Diffusion installation on a Linux partition viewed from Windows? Ritridata primarily supports NTFS, FAT32, and exFAT file systems on Windows. Linux ext4 partitions have limited support. For ext4 recovery, boot from a Linux live USB and use Linux-native recovery tools.
Q7: Does Ritridata work on Windows 11 specifically? Yes, Ritridata is compatible with Windows 10 and Windows 11. The scanning and recovery process is the same on both platforms.
Q8: How do I prevent this from happening again? Set up an automated backup of your SD outputs folder using Windows Backup or a tool like FreeFileSync. Schedule daily incremental backups to an external drive. For generations you consider portfolio-quality, maintain a separate curated folder with cloud sync enabled.
