Browse and selectively access files from archive downloads directly within your RBI session without sending the raw archive to the endpoint.

When you download archive files during an Remote Browser Isolation (RBI) session, the raw
archive would otherwise bypass the isolation boundary and its contents are never
inspected within the remote environment before reaching the user's device. The Archive
Viewer extends the RBI file viewing workflow to intercept supported
archive downloads, process them entirely within the remote container, and present you
with an interactive file explorer instead of delivering the archive to the user's
device.
All archive content inspection, file extraction, and viewing occurs inside the remote
container. Nothing from the archive reaches user's device unless you explicitly request
a targeted file download through the Archive Viewer. This gives you granular control
over what archive content you can access while keeping the browsing session secure.
The Archive Viewer supports the following archive formats:.zip,
.rar, .7z, .tar,
.gz, .tgz
Archive Viewer Experience
When you download a supported archive in an RBI session, the
Archive Viewer downloads and extracts the file within the isolated container instead
of delivering it to the endpoint. The Archive Viewer displays the archive content in
a file explorer directly within the session, showing the filename, file size, and
modification date.
You can perform the following actions in the Archive Viewer:
- Browse folders. Navigate into and out of folders within the archive. A
breadcrumb path tracks the current location and lets you return to any previous
level.
- View supported files. Click the View icon on a
supported file type — such as PDF, DOCX, XLSX, PPTX, TXT, or CSV — to open it in
the Archive Viewer without downloading it to the endpoint.
- Download individual files. Click the Download icon
on any file to deliver only that file to the endpoint, subject to the download
policy in the isolation profile.
- Open nested archives. Click the View icon on an
archive file listed inside the Archive Viewer to open it in a new Archive Viewer
tab, up to a maximum of three nesting levels.
- Sort entries. Use the sort dropdown in the upper-right corner of the
file explorer to sort archive contents by Name,
Size, Date Modified, or
Type.
- Open password-protected files from within
Archive Viewer. If an archive is password-protected, a password prompt appears
before the Archive Viewer opens in File Explorer.
Some archive files may be flagged as malicious by the firewall during
inspection, which can cause file sizes to display as 0 bytes in the
Archive Viewer. If an archive does not open correctly, verify that the
file is permitted by your security policies.
- Ensure that your browser's pop-up blocker is disabled for the site you are
browsing to open Archive Viewer in a new tab.
- If View Files in
Isolation is disabled, you can download archive
files directly to your system, provided the Download
Files option is enabled.
Nested Archive Navigation
You can open archives within archives — for example, a ZIP file inside another ZIP
file — directly from the Archive Viewer. Each nested archive opens in the same tab
within the remote browser. RBI enforces a maximum nesting depth
to prevent excessive resource use; the maximum supported level is three. When you
attempt to open a nested archive beyond three, RBI displays a
Failed to open nested archive notification with a message
indicating the maximum nesting limit has been reached, instead of opening another
Archive Viewer tab.
To retrieve a nested archive file without opening it in the Archive Viewer, click
Download on the archive entry. The file downloads
directly to the endpoint and does not launch another Archive Viewer session.
