Tally Prime Configuration Persistence: Backup and Restore of Application, Company, and User Settings

This Knowledge Base article explains where and how Tally Prime stores configuration data, including bank details, email (SMTP) settings, view/UI preferences, and customizations, and whether these settings can be preserved during reinstallation, upgrade, or migration.

It clarifies:

• Which settings are company-bound

• Which are application-level

• Which are user/machine-specific

• What can and cannot be safely copied

• Best practices to minimize reconfiguration effort

This document applies to Tally Prime (all current releases) on Windows standalone and multi-user environments.

Product / System Overview

Tally Prime is an on-premise accounting and compliance application that stores configuration data across multiple layers rather than a single settings file.

Configuration Storage Layers

Technical Architecture & Behavior

1. Company-Level Configuration (Persistent)

Stored inside company data folders, these settings are automatically restored when the company is restored.

Includes:

• Bank masters (account number, IFSC, bank name)

• Ledger & master configurations

• GST / statutory details

• Party email IDs

• Voucher & inventory configuration

• Cheque printing formats

• Company-attached TDL behavior

Storage Location (default):

C:\TallyPrime\Data\<CompanyFolder>

✔ Reinstall-safe
✔ Machine-independent

2. Application-Level Configuration (Partially Persistent)

Stored outside company data and lost on clean reinstall unless backed up manually.

Key File: tally.ini

Contains:

• SMTP server, port, SSL/TLS settings

• Default email sender ID

• Data path configuration

• Output directories

• License-related parameters

Default Locations:

C:\Program Files\TallyPrime\
C:\TallyPrime\

Example – Email configuration in tally.ini:

[Mail]
SMTPServer=smtp.gmail.com
SMTPPort=587
From=accounts@company.com
SSL=Yes

⚠️ Version-sensitive
⚠️ Copy only between same Tally Prime versions

3. TDL Customizations

Custom TDLs are external to company data unless explicitly embedded.

Location:

C:\TallyPrime\TDL\

✔ Must be backed up manually
✔ Must match Tally version compatibility

4. User & View Settings (Non-Portable)

These settings are user-profile and machine-specific.

Includes:

• Screen layouts

• Expand/collapse states

• User navigation behavior

• View filters & shortcuts

Stored at:

C:\Users\<Username>\AppData\Local\Tally\

❌ Not officially supported for migration
⚠️ May cause corruption if copied across systems

Use Cases & Environments

Applicable Scenarios

• OS reinstallation

• Tally Prime upgrade (same major version)

• Disk failure recovery

• Office PC replacement

• AMC-based IT support environments

Environment Types

• Standalone Tally Prime

• LAN multi-user setup

• On-premise accounting systems

Step-by-Step: Safe Backup Before Reinstall

Step 1: Backup Company Data

From Tally:

Gateway of Tally → Backup

OR manually copy:

C:\TallyPrime\Data\

Step 2: Backup Application Configuration

Copy the following:

tally.ini
TDL\

Step 3: Document Non-Portable Settings

✔ Screenshot:

• Email configuration screen

• Cheque printing settings

• Bank configuration screens

Restore Procedure After Reinstall

1. Install same Tally Prime version

2. Restore company data

3. Replace:

   tally.ini
   TDL\
   

4. Reopen Tally and verify:

   • Email test mail

   • TDL loading

   • Voucher behavior

Common Errors, Root Causes & Fixes

Security Considerations & Risks

• tally.ini may store email credentials

• Avoid sharing config files insecurely

• Restrict access to Tally installation directory

• Use App Passwords for Gmail / M365

• Do not copy AppData between users

Best Practices & Recommendations

✔ Always backup company data first
✔ Maintain same version during restore
✔ Keep TDL documentation
✔ Avoid copying AppData folders
✔ Use disk images / VM snapshots for zero-downtime recovery
✔ Maintain a Tally reinstall checklist

Conclusion

There is no single file in Tally Prime that stores all configurations. Settings are intentionally split across company data, application config, and user-specific storage.

With proper backups of:

• Company data

• tally.ini

• TDL folders

…you can reinstall Tally Prime with minimal reconfiguration effort, while avoiding corruption or instability.
