Cannot Open Vault File
Error: “Failed to open file” or “File not found”
Solutions:
Verify file exists
- Navigate to the folder in File Explorer
- Confirm the
.vaultfile is there - Check file name matches exactly (case-sensitive on macOS/Linux)
Check file permissions
- Windows: Right-click → Properties → Security → Make sure you have “Read” permission
- macOS/Linux:
ls -la filename.vault(should show read permissions) - Fix:
chmod 644 filename.vault(macOS/Linux)
File is locked by another program
- Close all CoraleVault windows
- Check Task Manager (Windows) or Activity Monitor (macOS) for lingering processes
- Reboot if necessary
File is on network drive or cloud storage
- Network interruptions can cause issues
- Copy vault file to local drive temporarily
- Try opening the local copy
File path contains special characters
- Avoid:
< > : " / \ | ? *in file names - Avoid non-English characters in path
- Rename to simple ASCII:
passwords.vault
- Avoid:
Error: “Invalid file format” or “Not a valid vault file”
Causes:
- File is corrupted
- File is not actually a CoraleVault file
- File was partially transferred (incomplete download/copy)
Solutions:
Check file size
- Minimum vault file: ~500 bytes
- If file is 0 bytes or suspiciously small, it’s corrupted
Check file header
- Windows:
certutil -hashfile passwords.vault SHA256 - macOS/Linux:
head -c 20 passwords.vault | xxd - Valid vault files start with binary header
- Windows:
Restore from backup
- Use your most recent backup
- See Backup & Recovery Guide
Try opening in older version
- If you recently upgraded, try previous version
- Download from GitHub Releases
Error: “Incorrect password”
See Forgot Master Password below.
Forgot Master Password
The Hard Truth
There is NO password recovery. This is not a bug—it’s the most important security feature.
Why no recovery?
- Master password is never stored (not even encrypted)
- Your data is encrypted with keys derived from the password
- Without the password, decryption is mathematically impossible
- Even we (the developers) cannot access your vault
What this means:
- If you forget your master password, your data is lost forever
- There is no “reset password” option
- There is no “security questions” backdoor
- There is no recovery service
What You Can Try
Try variations you might have used
- Common typos
- Different capitalization
- With/without numbers or symbols
- Old passwords you reused
Check if you wrote it down
- Password notebook
- Secure physical location (safe, drawer)
- Emergency contact might have copy
Search your computer for clues
- Notes apps
- Password hints (if you left any)
- DO NOT search for actual password in plain text files (security risk)
Restore from old backup
- If you have a backup from when you remembered the password
- Old cloud sync versions (Dropbox, Google Drive have version history)
Prevention for Next Time
Write down master password on paper
- Store in safe, locked drawer, or safety deposit box
- Give copy to trusted family member
Use a memorable passphrase
- Not a random password (easier to remember)
- Example:
Correct-Horse-Battery-Staple-2025! - See Getting Started Guide
Practice typing it
- Type it 10 times when you first create it
- Muscle memory helps
Don’t change master password too often
- Only change if compromised
- Each change is a risk of forgetting
Corrupted Vault File
Symptoms
- “Invalid file format” error
- Application crashes when opening vault
- Garbled data or missing entries
- File size is 0 bytes or much smaller than expected
Causes
- Hard drive failure or bad sectors
- Application crash during save
- Incomplete file transfer
- Cloud sync conflict
- Antivirus quarantine/repair
Recovery Steps
Step 1: Restore from Backup
This is why backups are critical! See Backup & Recovery Guide.
Where to find backups:
- Manual backups (external drives, USB)
- Cloud storage (Dropbox, Google Drive, OneDrive)
- Cloud version history (if file was synced)
- System backup (Time Machine, Windows Backup)
Restoring from cloud version history:
Dropbox:
- Right-click file → Version history
- Select previous version before corruption
- Download and test
Google Drive:
- Right-click file → Manage versions
- Download earlier version
OneDrive:
- Right-click file → Version history
- Restore previous version
Step 2: Check for Temporary Files
CoraleVault may have created temporary backup during last save:
Windows:
- Same folder as vault:
passwords.vault.tmp,passwords.vault.bak - Temp folder:
C:\Users\YourName\AppData\Local\Temp
macOS:
- Same folder:
passwords.vault.tmp,passwords.vault.bak - Temp:
/tmp/(automatically cleared on reboot)
Linux:
- Same folder:
passwords.vault.tmp,passwords.vault.bak - Temp:
/tmp/
Try opening these files directly (rename to .vault extension first).
Step 3: File System Recovery

Step 4: Data Recovery Software
If no backups exist and file is corrupted, try data recovery tools:
Free tools:
- Recuva (Windows)
- TestDisk/PhotoRec (All platforms)
- Disk Drill (Free trial)
These might recover older versions of the file from disk.
Prevention
Multiple backups (3-2-1 rule)
- 3 copies total
- 2 different media (drive + cloud)
- 1 off-site (cloud or different location)
Cloud storage with versioning
- Dropbox keeps 30 days of history
- Google Drive keeps 30 days
- OneDrive keeps version history
Regular manual backups
- Weekly: Copy to external drive
- Monthly: Copy to different location
Don’t edit vault on unstable storage
- Avoid network drives
- Don’t use vault from USB drive directly (copy to local first)
Performance Issues
Application is slow to open vault
Cause: Large vault files (1000+ entries) or slow hard drive.
Solutions:
Move vault to SSD
- HDDs are much slower for random access
- SSD reduces open time significantly
Close other programs
- Free up RAM
- Reduce CPU load
Defragment hard drive (Windows HDD only)
- Don’t defragment SSDs
- Windows:
defrag C: /O
Check system resources
- Task Manager (Windows) or Activity Monitor (macOS)
- Look for high CPU or memory usage
Searching is slow
Cause: Large vault (1000+ entries).
Solutions:
Use groups to organize
- Filter by group before searching
- Reduces search scope
Upgrade system RAM
- Minimum 4 GB recommended for large vaults
- 8 GB+ ideal
Application uses too much RAM
Normal RAM usage:
- Small vault (< 100 entries): 50-150 MB
- Medium vault (100-500 entries): 150-300 MB
- Large vault (500-1000 entries): 300-500 MB
- Very large vault (1000+ entries): 500 MB - 1 GB
If using much more:
- Restart application
- Check for memory leaks (report bug)
- Split vault into multiple files
Import/Export Problems
Import fails with “Invalid CSV format”
Solutions:
Check CSV encoding
- Must be UTF-8
- Open in text editor, save as UTF-8
Check CSV structure
- Must have header row:
Title,Username,Password,URL,Notes,Group - Commas must be properly escaped
- Quotes around fields with commas
- Must have header row:
Check for special characters
- Some password managers export with strange encoding
- Try opening CSV in Excel/LibreOffice first
- Re-save as clean UTF-8 CSV
Split large imports
- If importing 1000+ entries, split into multiple files
- Import in batches
Export creates empty file
Solutions:
Check file permissions
- Export location must be writable
- Try exporting to Desktop or Documents
Check disk space
- Large vaults need significant disk space
- Ensure 100+ MB free
Vault must be unlocked
- Cannot export from locked vault
Imported entries have garbled text
Cause: Encoding mismatch.
Solutions:
Re-export from source with UTF-8
- Chrome: Export as UTF-8 CSV
- Excel: Save As → CSV UTF-8
Convert encoding
- Open CSV in Notepad++
- Encoding → Convert to UTF-8
- Save
