Some businesses keep every file forever, and others delete files too aggressively. Both habits create risk. A shared drive that holds everything makes current work hard to find and keeps sensitive information around longer than it needs to be. A drive cleared too quickly can leave a business without the records it needs to answer a tax question or explain a past decision.
A clear retention approach sits between those two extremes and rests on three rules:
- You keep anything tied to the business, its finances, or a decision.
- You archive closed work instead of deleting it.
- You delete working files whose contents already live in an official record.
This article walks you through a sorting and archiving process built around a seven-year retention period. You finish with a cleaner active workspace and a repeatable rule for every file you decide on.
Before You Start
You need a few things in place before you begin.
- Access to the shared drive or cloud storage platform you plan to review
- Access to the paper files you plan to review
- A list of active and closed projects
- Your file naming conventions, if your business has them
- A blank spreadsheet for the retention log
- Contact information for your accountant or legal advisor
- A decision on who has authority to approve deletions
The Process
The steps below take you from sorting files to setting a schedule for the seven-year review.
Step 1. File Inventory by Project
You start by grouping files by the project or client they support. Each top-level folder in the shared drive should map to one of these groups. Files that do not fit a group go into a temporary "To Review" folder so you can decide on them in Step 4.
Paper files follow the same grouping. A labeled box or drawer for each project keeps paper and electronic records aligned.
Step 2. Keep Criteria
You keep anything tied to one of three areas:
- The business itself, such as licenses and contracts
- The business's finances, such as invoices and tax filings
- A decision, such as approval emails and board minutes
These files stay, either in the active workspace or in the archive. A file that meets any one of these criteria is not a candidate for deletion until it reaches the end of its retention period.
Step 3. Archive for Closed Projects
Files from closed projects move to an archive rather than being deleted. The archive keeps them available but out of the active workspace, so current work is easier to find.
A simple archive structure works well:
- A top-level "Archive" folder in the shared drive
- A subfolder for each year the project closed
- A subfolder for each project inside the year
Access to the archive can be narrower than access to the active workspace. Team members still reach the files they need, and closed records are protected from accidental edits.
Step 4. Delete Criteria
You delete files that are not attached to a project and do not affect an outcome. Working files whose contents already live in an official record fall into this group.
Records exported from a system and cleaned up in a scratch file are a good example. The scratch file serves its purpose while you correct names and remove duplicates. The clean records then move into the official file, and the scratch file can go.
One question guides every deletion decision: does the final version of this information live somewhere official? A yes means the working copy can go. A no means the file stays until the information reaches an official record.
Step 5. Seven-Year Retention
Archived files are retained for seven years, paper and electronic alike. Seven years is a common, conservative benchmark that covers most federal tax record retention periods.
Retention requirements vary by industry and record type. Employment and health records can carry different periods, and state rules can add their own. You confirm specific periods for your business with your accountant or legal advisor and note any exceptions in your retention log.
Step 6. Retention Log
A retention log tracks each archived group of records and the date it comes up for review. The spreadsheet uses these columns:
- Record Group
- Location
- Format
- Date Archived
- Review Date
- Decision
The Review Date equals the Date Archived plus seven years, unless your advisor has given a different period for that record type. The Format column records the storage medium for each group.
Step 7. The Year-Seven Decision
Each record group reaches its review date in the log. You make one of two decisions at that point:
- A move to a deeper archive layer, such as lower-cost long-term storage or an offsite box
- Deletion of files that are no longer needed
You record the decision and the date in the Decision column. A calendar reminder each January keeps the review on schedule and lets you handle every group due that year in one session.
Worked Example
Harvest Table Catering is a small catering company with five employees. The owner, Lena Brooks, noticed that the shared drive held four years of event files mixed in with current work.
Lena grouped the files by event and sorted them using the steps above. Closed events from 2023 through 2026 moved into the archive by close year. Records tied to finances and decisions, such as contracts and invoices, stayed with each event in the archive.
She found a file named "Guest List Export Cleanup" for the Riverside Gala. The team had used it to clean a guest list exported from the registration system. The clean list already lived in the official event file, so Lena deleted the scratch file.
Lena confirmed with her accountant that seven years covered the company's tax records and that her state's rules did not require a longer period for payroll records. She built a retention log and set a January reminder for the annual review.
Checking Your Work
You use this checklist to confirm your retention approach is in place.
- Every file in the active workspace belongs to a current project or business function.
- Closed project files sit in the archive, grouped by close year.
- Records that meet the keep criteria in Step 2 are kept.
- Each deleted file had its final version in an official record.
- The retention log lists every archived record group.
- Each review date reflects seven years or the period your advisor confirmed.
- Paper and electronic records follow the same retention rules.
- A recurring reminder is set for the annual review.
