How to Share Large Folders on Windows and Mac

Send a complete folder while keeping its structure intact. Learn when to use ZIP, how to prepare the folder, and what recipients should check.

The simplest way to share a folder reliably is to prepare one clean delivery folder, package it as a ZIP if needed, and upload it to a service that accepts the resulting size. If the service supports folder uploads, test whether the recipient download preserves the same structure.

Folder structure matters when a project contains linked images, audio, or supporting documents. Sending only the main project file often leaves the recipient with missing assets.

Prepare a delivery copy

Copy the files you intend to share into a new folder. Keep your working project intact. Remove accidental duplicates, temporary exports, and private notes from the delivery copy, but do not remove files that the project references. Open the copy before packaging it.

Choose a useful top-level name such as Client_Project_v02_2026-10-10. Use short, descriptive names and avoid characters that are invalid on the recipient's operating system. Keep related assets together rather than flattening every file into a single directory.

Create a ZIP on Windows or Mac

On Windows, right-click the prepared folder and use the ZIP or compressed-folder command available in File Explorer. Menu wording varies by Windows version. On Mac, Control-click the folder in Finder and choose Compress. Give the new archive a name that includes the delivery version.

The official Windows ZIP instructions and Mac compression instructions cover the built-in tools. A normal ZIP is not automatically password protected.

Check size and free space

Look at the finished ZIP's size before uploading. A folder full of videos or JPEGs may produce an archive almost as large as the folder itself. ZIP is still useful for packaging even when it saves little bandwidth.

The recipient needs space for both the archive and its extracted contents while unpacking. For example, a 40GB archive that expands to 42GB needs roughly 82GB available if both copies remain, plus working space. Do not promise that the download size is the full storage requirement.

Upload, test, and hand over

  1. Upload the archive or the complete folder and wait for the completion message.
  2. Open the recipient link separately from any management page.
  3. Download and extract a test copy into a new location.
  4. Check the folder names, file count, and a few important files.
  5. Send the link with the archive size and the access deadline.

If recipients only need a small portion, consider separate, clearly named packages. Splitting by useful delivery units is usually easier to understand than a multipart archive requiring every segment to extract.

Common questions

Can I email the ZIP instead?

Only if it fits the sender's and recipient's attachment rules. ZIP packaging does not bypass those limits. Use a download link for a large archive.

Why does the folder open but the project reports missing files?

The application may reference assets outside the folder you sent. Use its packaging or collection feature, then test the packaged copy. The video project handoff guide explains this workflow.
