5 Reliable Methods to Recover Deleted PSB File?

PAGE CONTENT:

In the realm of digital design and image editing, file formats play a critical role in determining the scale and flexibility of a project. One such format used by Adobe Photoshop professionals is the PSB file format. If you've worked on large Photoshop files, chances are you've come across or even used this format. However, like all digital assets, PSB files are also susceptible to accidental deletion or data loss.

This guide will walk you through what a PSB file is, why it matters, and the most effective ways to recover deleted or unsaved PSB files.

What is a PSB File?

A PSB file is the Photoshop Big Document Format, an extended version of the more common PSD (Photoshop Document). While PSD is adequate for most image editing tasks, it has certain limitations - such as a maximum file size of 2 GB and pixel dimensions of 30,000 x 30,000.

In contrast, the PSB format lifts those constraints and allows:

• Files larger than 2 GB in size
• Image dimensions exceeding 300,000 x 300,000 pixels
• Support for extensive layers, vector paths, text layers, effects, smart objects, and embedded multimedia elements

Due to these features, PSB files are primarily used for:

• Large-scale print media
• Gigapixel imagery
• Architectural renders
• 3D texturing projects

Key Differences Between PSB and PSD

Feature	PSD	PSB
Max File Size	2 GB	~4 Exabytes (theoretical)
Max Dimensions	30,000 x 30,000 px	300,000 x 300,000 px
Compatibility	Widely supported	Limited to newer Photoshop
Use Case	Standard projects	Extremely large projects

Programs That Support PSB Files

• Adobe Photoshop (CS and newer)
• Photopea (Online)
• Some limited support in third-party viewers and converters

Common Reasons for PSB File Loss

Despite its robustness, a PSB file is not immune to loss. Below are common causes of PSB file deletion or corruption:

1. Accidental Deletion: Files mistakenly deleted from storage or Photoshop.
2. Formatting Errors: Drive or partition formatting without backups.
3. System Crash: Sudden OS shutdowns while saving PSB files.
4. Photoshop Errors: Application crashes or freezing during project saving.
5. Malware or Ransomware Attacks: Can encrypt or delete PSB files.
6. Transfer Failures: Interruptions during file copy or move operations.
7. Drive Corruption: Issues with external drives or USBs where files are saved.

How to Recover Deleted PSB Files? [5 Methods]

If you've lost a valuable PSB file, act fast. Below are practical ways to restore it depending on how it was lost:

Method 1. Recover Deleted PSB File from Recycle Bin/Trash

This is your first step if the file was recently deleted:

Steps:

Windows:

• Open Recycle Bin on your desktop.
• Search for your deleted .psb file.
• Right-click > Restore.

Mac:

• Open Trash from the Dock.
• Locate the .psb file.
• Right-click > Put Back.

If you don't find it here, move to the next recovery options.

Method 2. Restore PSB Files from File History or Time Machine Backup

If you had set up a backup system beforehand, restoring is easy.

Windows (File History):

• Go to the folder where the PSB file was saved.
• Right-click > Properties > Previous Versions.

• Choose the correct version > Click Restore.

Mac (Time Machine):

• Connect your Time Machine backup drive.
• Launch Time Machine, click Time Machine icon on menu bar, choose Browse Time Machine Backups.
• Navigate to the folder containing your lost PSB file.
• Click Restore.

Method 3. Recover Lost PSB Files from Adobe Creative Cloud (If Synced)

If you've saved files to the cloud, versioning may help you recover deleted or previous versions.

Steps:

• Go to Adobe Creative Cloud.
• Sign in and click on Files > Deleted or Synced Files.

• Restore from available backups or autosaves.

Adobe Creative Cloud may also retain file versions if you've enabled versioning.

Method 4. Use Data Recovery Software to Recover Lost PSB Files

If no backup exists, third-party recovery tools can scan your drive for deleted PSB files. These tools work even after formatting or partition loss.

Among these recovery tools, Donemax Data Recovery is an outstanding one. It supports to recover 2000+ file formats including .psb.

Steps to recover deleted or lost PSB files:

Step 1: Stop Using the Affected Drive

If you keep using the drive where the PSB file was located, there's a risk new data could overwrite the deleted file sectors, making recovery impossible.

Step 2: Install Recovery Tool

To prevent further data overwriting, install the recovery software on a different partition or drive. Donemax Data Recovery is compatible with Windows and macOS, download and install it on your computer, then open it, select the drive where you delete or lose the PSB files.

Step 3: Start the Scan

Click on Scan button. Donemax Data Recovery will deeply scan the selected drive and find all recoverable files including the lost PSB files.

Step 4: Filter and Locate PSB Files

• Use filters to search by file extension .psb
• Donemax Data Recovery allows searching by name if partially known.

Step 5: Preview and Recover

• Donemax Data Recovery allows previewing, verify the integrity of the PSB file.
• Select the wanted PSB files, click on Recover button. Save the recovered file to a different drive to avoid writing over other recoverable data.

💡 Tip: Stop using the drive immediately after file loss to avoid overwriting deleted files.

▪️ Tips for Maximizing Recovery Success:

• Act Quickly: The sooner you scan after deletion, the higher the success rate.
• Use Deep Scan: While slower, it's more effective for older or fragmented files.
• Do Not Reformat the drive again - it reduces recovery chances.
• Avoid Free Tools for Mission-Critical Files: Invest in a trusted premium tool if the PSB file is essential for work or business.

▪️ Real-World Use Case:

"A graphic designer working with a 5 GB architectural layout saved in PSB format accidentally deleted the file while clearing up storage. Because AutoSave was disabled and the file was not backed up, recovery software was the only option."

Using Donemax Data Recovery, they performed a deep scan of the SSD. After two hours, the PSB file was recovered intact with all layers and elements preserved, saving dozens of hours of work.

Method 5. Recover Unsaved PSB Files in Photoshop

Photoshop has built-in auto-recovery functionality which may save you if the file was never manually saved.

Steps to Find AutoRecovered PSB Files:

1. Navigate to Photoshop's AutoRecover folder:
   • Windows:

     C:\Users\<username>\AppData\Roaming\Adobe\Adobe Photoshop<version>\AutoRecover

   • Mac:

     /Users/<username>/Library/Application Support/Adobe/Adobe Photoshop <version>/AutoRecover

2. Look for files with .psb or temp extensions.
3. Open the file directly in Photoshop.
4. Save it manually to a secure location.

💡 Note: Auto-recovery is only available if enabled in Photoshop preferences.

Tips to Prevent Future PSB File Loss

To avoid future mishaps, here are key prevention strategies:

1. Enable Auto Save in Photoshop
   • Go to Edit > Preferences > File Handling
   • Enable Auto Save every X minutes
2. Use External and Cloud Backups
   • Regularly copy files to an external drive
   • Use services like Google Drive, OneDrive, or Creative Cloud
3. Create Incremental File Versions
   • Save work with versioning like project_v1.psb, project_v2.psb, etc.
4. Use UPS (Uninterruptible Power Supply)
   • Prevents corruption due to power failure
5. Avoid Heavy Modifications without Saving
   • Save the file before applying high-memory processes or filters
6. Regularly Update Photoshop
   • Bug fixes often resolve autosave or stability issues
