Data room vs shared folder

Last updated September 2026

Why this question comes up

Founders selling a business for the first time, or attorneys running a smaller deal, sometimes ask whether they really need a virtual data room. They already have Google Drive. They already pay for Dropbox. Setting up another tool feels like overhead.

The answer depends on the deal. The more buyers you have, the more their access needs to differ, and the more you need a record of what each one reviewed, the more a data room earns its place.

What shared folders do well

General file tools are built for everyday sharing and collaboration, and they have real controls. Google Drive lets you share a file or folder with specific people, choose whether each person can view, comment, or edit, and lets owners turn off download, print, and copy for viewers and commenters. Business tiers of Dropbox and Box add their own sharing and security features. For drafting with your own team, these are the right tools.

What a data room adds on a sell side deal

A data room is organized around buyers rather than files. Using LockRoom as the example, here is what that means in practice.

1. A room staged by buyer group

Each bidder is a buyer group with its own permissions, and groups are invisible to each other. Moving a shortlisted buyer to round 2 is a permission change on the group, not a new round of sharing (how buyers are invited).

2. Four permission levels per group, folder, and file

View Watermarked, Download Watermarked, View Original, and Download Original, set per buyer group, per folder, and per file. A sensitive folder can stay hidden from a group entirely, and every permission change is recorded in the audit log (how document permissions work).

3. Watermarks that identify the viewer

Documents show as watermarked previews by default, and the watermark identifies the viewer, which discourages screenshots and leaks. You decide per buyer group whether downloads are watermarked or original files (how watermarks work).

4. Per buyer activity reporting

The audit log records which documents each buyer viewed and downloaded, with timestamps and IP addresses. Owners and admins can get a daily digest email, so you can see which bidders are engaged without opening the room (how to track buyer activity).

5. An audit trail you can export at close

Every view, download, and permission change is logged. Export the log to PDF for the deal file; closed rooms are archived with the audit record kept for 7 years (how to export the audit log). If your firm is a broker dealer, its recordkeeping obligations under SEC Rule 17a-4 and FINRA Rule 4511 sit with the firm, not the software, so whichever tool you use, make sure you can export the full record at close.

6. What to ask about NDAs and Q&A

Some data rooms offer an in room NDA click through and a structured Q&A module. LockRoom does not list either today, so NDA execution stays in your normal process: the NDA comes back signed, then you add that buyer to its group. If your process needs either feature, ask each vendor.

When shared folders are fine

Three scenarios where a shared folder is the right tool:

• Internal team collaboration. Document drafting, version control, real time editing among internal team members. Google Drive and Dropbox are built for this. Don't use a data room for it.
• Sharing non confidential materials externally. Marketing assets, public information, draft materials shared informally.
• Receiving documents from one trusted counterparty for a non transactional purpose. A vendor sending you their proposal. A consultant sending you their draft.

When a data room is worth it

• Several competing buyers. Bidders must not see each other, and each needs different access. See the sell side M&A process.
• Access that changes by round. First round buyers see the CIM and summary financials; the shortlist sees more.
• You need to read buyer engagement. Which bidders opened which documents, and when.
• You need a record at close. An export of who saw what, and when, for the deal file.
• A fundraise with several investors in diligence. The same staging and activity questions apply.

What about Box?

Box is a general purpose secure file platform that many enterprises use for document management. Before using it, or any general file tool, for a sell side process, check whether it gives you access staged by buyer group, viewer watermarks, a per buyer activity record, and an audit log you can export at close.

The cost comparison

Google Drive may already be part of your Workspace plan, so a data room looks like a new line item. LockRoom is $375 a month for one room, or $6,000 a year for unlimited rooms, with unlimited users and no per page fees. The useful comparison is not price alone: go through the six items above, mark which ones your current setup covers for this deal, and decide whether the gap is worth the price. For quote based VDRs, run the same test against the written quote.
