SharePoint does not need to be a dead end for a ZIP archive. For most users, the reliable method is to download the ZIP file, extract it on the computer, and upload the extracted files or folder to the intended SharePoint library. For repeatable work, an authorized Power Automate flow can extract an archive directly to a SharePoint folder.
Before starting, confirm that you can download from the source library and upload to the destination library. If the archive contains controlled procedures, forms, or records, identify the approved destination and the person responsible for checking the extracted files before anyone uses them.
How To Unzip Files In SharePoint?
Method 1: Download, extract, and upload
This is the simplest method for an occasional ZIP file in SharePoint Online.
- Open the SharePoint document library and select the
.zipfile. - Select Download. Microsoft documents the same download command for files and folders in SharePoint.
- Open the downloaded location in File Explorer.
- Right-click the ZIP file, select Extract All, choose a local working folder, and complete the extraction.
- Inspect the extracted folder before uploading. Confirm that expected files are present and that the folder hierarchy is sensible.
- Open the destination SharePoint library. Create the destination folder first if the extracted files need their own location.
- Select Upload, or drag the extracted files or folder from File Explorer into the library. Microsoft notes that uploading requires contributor permission.
- Wait for the upload to finish, then open several representative files from SharePoint to verify that the transfer succeeded.
The browser performs the download, but Windows or another approved archive utility performs the extraction. SharePoint then receives the extracted files through its normal upload process. Microsoft provides current instructions for downloading files and folders from SharePoint and uploading files and folders to a library.
Method 2: Use a synced SharePoint library
If the library is already synced to File Explorer, download or copy the ZIP file to a controlled local working folder, extract it there, and then copy the extracted files into the synced destination folder. Watch the OneDrive status icons until synchronization is complete, and verify the files in the SharePoint browser view before considering the transfer finished.
Avoid extracting a large archive directly inside a synced folder without first understanding what the archive contains. Immediate synchronization can propagate unwanted duplicate files, deep folder structures, or obsolete documents before they are reviewed.
Method 3: Use an approved Power Automate flow
Microsoft’s SharePoint connector includes an Extract folder action that accepts a source archive path, a destination folder path, and an overwrite setting. This can support an authorized repeatable workflow when the archive arrives in a known library and the destination rules are stable.
Before using automation, test it with noncritical files. Confirm the connection account’s permissions, the destination path, overwrite behavior, naming conventions, and the handling of a failed or partial run. Automation moves files; it does not determine whether a document is approved, current, or suitable for use.
ZIP file versus a downloaded SharePoint folder
An existing ZIP file stored in a library follows the download, extract, and upload sequence above. A SharePoint folder is different: when you select a folder, multiple files, or multiple folders and choose Download, Microsoft states that the browser creates a ZIP archive containing the selected contents. Extract that downloaded archive locally if you need to work with the folder outside SharePoint.
What Are The Common Issues When Unzipping Files In SharePoint?
There is no Extract command in the library
Use the download, local extraction, and upload method. If direct extraction is a recurring business requirement, ask the SharePoint or Power Platform owner whether an approved Power Automate flow is appropriate.
The Download or Upload option is missing
Confirm that an item is selected and that your account has permission for the action. Microsoft notes that contributor permission is required to create and upload files or folders. A library administrator can confirm whether permissions, checkout, or content approval settings affect the destination.
The archive does not extract cleanly
Download the ZIP file again and compare the result with the source. If the archive still fails, treat it as a source-file problem rather than uploading a partial extraction. Request a replacement archive from its owner.
Some files fail during upload
Look for unusually long paths, unsupported names, insufficient permissions, or duplicate names in the destination. Shorten the local folder structure only when doing so does not break an approved naming convention or record relationship.
Existing files have the same names
Do not overwrite them reflexively. Determine whether the upload represents a replacement, a new revision, or a separate record set. When a controlled file truly must be replaced, follow the organization’s approved method for replacing a document in SharePoint so version history and approval requirements are not bypassed.
Files appear in File Explorer but not in SharePoint
Check the OneDrive synchronization status and resolve any reported error. Verify completion in the browser view rather than assuming that a local copy has reached the library.
Document-Control Risks When Extracting Zip Files
These controls matter when an archive contains documents used to direct work, demonstrate conformity, or retain evidence. They may be unnecessary for temporary or noncontrolled material.
- Uncontrolled copies: Extraction can create local copies outside the governed library. Remove temporary copies according to the organization’s retention and security rules.
- Version ambiguity: A ZIP archive can contain files that are older than the approved library versions. Compare revision identifiers, approval status, or other controlled metadata before release.
- Lost metadata: Folder extraction preserves files and folders, but it does not automatically recreate SharePoint columns, approval status, retention labels, or workflow history.
- Duplicate records: Uploading extracted files into an occupied folder can create naming conflicts or unintended replacements.
- Access exposure: A local extraction may place restricted files on a device or location with different access controls.
For a broader governance approach, use a defined SharePoint document-management process that assigns ownership, metadata, approval, versioning, retention, and access responsibilities. Unzipping is only a file-handling step inside that process.
SharePoint Zip File Checklist for Quality and Operations Teams
- Confirm the archive came from an expected and trusted source.
- Identify the correct destination library and folder before extraction.
- Confirm that the person performing the task can download and upload.
- Extract to an approved local working location.
- Review folder structure, file names, and expected file count before upload.
- Check for duplicate names and decide whether each file is new, revised, or already present.
- For controlled documents, verify revision, approval, effective status, and required metadata.
- Upload the extracted files or folder and wait for the transfer or synchronization to complete.
- Open representative files from SharePoint and confirm access from the intended user group.
- Remove temporary local copies when policy requires it.
The practical rule is simple: extract the archive through an approved method, then verify the destination and the files. A successful upload proves that files moved; it does not by itself prove that the documents are current, approved, or ready for operational use.
