UPSC DRDO SAO • SO/SSA LDCE • UPSC Admin Officer • CSIR SO/ASO
⚡ Quick Answer & AI Exam Snapshot (TL;DR)
While CrackTarget’s existing MOP notes cover Chapter 7 (Noting) and Chapter 8 (Drafting), the Central Secretariat Manual of Office Procedure (CSMOP, 16th Edition, DARPG) also tests File Structure (Part I Notes + Part II Correspondence + Appendix), File Numbering (Functional vs Conventional), Record Retention Categories under the Public Records Act, 1993 (Category ‘A’: Permanent & Microfilmed, Category ‘B’: Permanent & Not Microfilmed, Category ‘C’: Kept up to 10 Years), Time Limits for Disposal of Receipts (VIP references: 30 days), and the 4 Security Gradings of Classified Documents (Top Secret, Secret, Confidential, and Restricted).
1. Anatomy of a Government File, File Numbering & Colour Priority Slips (CSMOP)
- Two Main Parts of a File:
- Notes Portion (Left Side of File — Green/Buff Sheet): Contains the serial record of notes written on a Paper Under Consideration (PUC) or Fresh Receipt (FR), ending with the decision of the Competent Authority.
- Correspondence Portion (Right Side of File): Contains all incoming communications (PUCs/FRs), outgoing office copies of drafts issued, and inter-departmental references, numbered serially in red ink on the top right corner.
- Standing Note / Running Summary of Facts: Placed on the file to save senior officers from reading bulky old papers. When a file reaches 150 pages or more, it is closed as Volume-I and a new Volume-II is opened!
- 4 Elements of Functional File Numbering vs Conventional File Numbering:
- Functional File Number (4 Tiers):
Basic Head (Function — 2 digits) / Primary Head (Activity — 2 digits) / Secondary Head (Operation — 2 digits) / Tertiary Head (Subject — 2 digits)+ Serial/Year/Section (e.g.,11013/4/2026-Estt.(A)). - Conventional File Number:
File No. / Subject Code / Serial No. / Year – Section Name.
- Functional File Number (4 Tiers):
- 3 Action Priority Labels (Urgency Grading Slips):
- ‘Immediate’ (Red Label): Highest priority—must be dealt with on the same day / immediately (includes Parliament Questions and Court Cases).
- ‘Priority’ (Blue/Green Label): Precedence over ordinary work—must be disposed of within 72 hours / 3 days.
- ‘Top Priority’ / ‘Today’: Used in Defence/PMO/Parliament sessions for same-hour movement.
2. Categorization & Retention of Records (Category ‘A’, ‘B’ & ‘C’) & Public Records Act, 1993
This table is tested in almost every UPSC SO/SSA LDCE and DRDO SAO exam:
| Record Category | Meaning & Retention Period | Types of Files Included & Archival Transfer |
|---|---|---|
| Category ‘A’ (“Keep and Microfilm / Digitise”) |
PERMANENT Preservation (Precious historical/constitutional value; microfilmed/digitised because original paper is required for frequent reference or is priceless). | Files containing Cabinet Notes, Presidential Orders, Acts/Legislation files, International Treaties, and landmark policy decisions. Review & NAI Transfer: Reviewed at 25th year and transferred to the National Archives of India (NAI)! |
| Category ‘B’ (“Keep — Do Not Microfilm”) |
PERMANENT Preservation (Important permanent administrative files, NOT microfilmed in routine initially). | Framing of Statutory Rules/Regulations, Permanent Service/Property Rules, Boundary files. Review & NAI Transfer: Reviewed at 25th year and transferred to NAI under the Public Records Act, 1993. |
| Category ‘C’ (Limited Duration: C-1, C-3, C-5, C-10) |
TEMPORARY Preservation for a specified number of years NOT EXCEEDING 10 YEARS (e.g., C-1 = 1 yr, C-3 = 3 yrs, C-5 = 5 yrs, C-10 = 10 yrs). | Routine establishment, house-building advances, leave/medical/TA files. Exam Trap: Can a Category ‘C’ file ever be marked for 15 years (C-15)? NO! Under CSMOP, the maximum retention period under Category ‘C’ is 10 YEARS! |
| e-Files in e-Office | Category I (Permanent — 10+ Years / NAI) vs Category II (1 to 10 Years) | Under e-Office 7.0 (developed by NIC and nodal agency DARPG), physical Categorization A & B are merged into Category I (Permanent Digital Preservation). |
3. Security Grading of Classified Documents & Mandatory Disposal Time Limits
| Security Grading | Criteria for Classification (Manual of Departmental Security Instructions, MHA) | Who Can Authorize & How It Is Handled |
|---|---|---|
| 1. TOP SECRET | Information whose unauthorized disclosure would cause EXCEPTIONALLY GRAVE DAMAGE to the nation (war plans, nuclear/defence codes, vital intelligence). | Authorized by an officer not below the rank of Joint Secretary. Kept in double-locked steel safes; handled personally by officers. |
| 2. SECRET | Information whose unauthorized disclosure would cause SERIOUS INJURY to national interest, or cause serious embarrassment to the Government, or give great advantage to a foreign nation (Cabinet Papers!). | Authorized by an officer not below the rank of Under Secretary. Sent in double sealed covers (inner cover marked Secret with addressee’s name; outer cover has NO security mark!). |
| 3. CONFIDENTIAL | Information whose unauthorized disclosure would be PREJUDICIAL to the interests of the nation, or cause administrative embarrassment (e.g., APAR dossiers, departmental vigilance inquiries, exam papers). | Authorized by an officer not below the rank of Section Officer / Desk Officer. |
| 4. RESTRICTED | Applied to official books/manuals meant Strictly for Official Use Only and not for publication (e.g., Departmental Defence Manuals). | Lowest tier of classification; single cover. |
Mandatory Time Limits for Disposal of Receipts in Ministries (CSMOP):
- Acknowledgement of VIP References (MPs, Ministers, Governors): Within 15 DAYS; Final Reply within 30 DAYS!
- Representations from Government Servants on Service Matters: Within 30 DAYS (Appeal disposal within 45–60 days).

🎯 High-Yield Exam One-Liners (Last-Minute Revision Box)
- The Central Secretariat Manual of Office Procedure (CSMOP) is published by the Department of Administrative Reforms and Public Grievances (DARPG).
- A standard Government file has two main parts: Notes Portion (left side) and Correspondence Portion (right side).
- When a physical file becomes bulky and reaches 150 PAGES, it is stitched and marked Volume-I, and a new Volume-II is opened.
- Under CSMOP, the ‘Channel of Submission’ of a file should ordinarily not exceed FOUR (4) levels before final decision.
- Functional File Numbering uses a 4-tier system: Basic Head (Function), Primary Head (Activity), Secondary Head (Operation), and Tertiary Head (Subject).
- Physical records are classified into 3 categories for preservation: Category ‘A’, Category ‘B’, and Category ‘C’.
- Category ‘A’ means ‘Keep Permanently and Microfilm/Digitise’; Category ‘B’ means ‘Keep Permanently but do NOT Microfilm initially’.
- Category ‘C’ means ‘Keep for a specified period NOT exceeding 10 YEARS’ (C-1, C-3, C-5, C-10); there is NO Category C-15.
- Under the Public Records Act, 1993, permanent records (Category ‘A’ and ‘B’) are appraised at the 25th year and transferred to the National Archives of India (NAI).
- In the digital e-Office system, physical Categories ‘A’ and ‘B’ are merged into ‘Category I’ (Permanent) and Category ‘C’ becomes ‘Category II’ (up to 10 years).
- The 4 security gradings of classified official documents in descending order are: Top Secret > Secret > Confidential > Restricted.
- ‘Top Secret’ is assigned when disclosure would cause ‘Exceptionally Grave Damage’ to national security (authorized by Joint Secretary or above).
- ‘Secret’ is assigned when disclosure would cause ‘Serious Injury’ to national interest (authorized by Under Secretary or above); all Cabinet Papers are graded at least ‘Secret’.
- ‘Confidential’ is assigned when disclosure would be ‘Prejudicial’ to national/administrative interest (authorized by Section Officer or above).
- When dispatching a ‘Top Secret’ or ‘Secret’ document by post, the INNER sealed cover bears the security grading and name of the officer, while the OUTER cover bears ONLY the address and NO security mark!
- Communications received from Members of Parliament (VIP References) must be acknowledged within 15 DAYS and replied to finally within 30 DAYS.
- Under DARPG’s revised CPGRAMS norms, public grievances must be disposed of within 21 DAYS.
- e-Office Mission Mode Project is designed and developed by the National Informatics Centre (NIC) with DARPG as the nodal department.

❓ Frequently Asked Questions (Exam FAQs)
Q: What is the difference between Category ‘A’ and Category ‘B’ files in CSMOP?
Both Category ‘A’ and Category ‘B’ files are preserved permanently and transferred to the National Archives of India at the 25th year. However, Category ‘A’ means ‘Keep and Microfilm/Digitise’ (for priceless historical/policy files), whereas Category ‘B’ means ‘Keep but do NOT Microfilm’ initially.
