File Viewer Plus Review — Fast, Lightweight, and Versatile

How to Open Any File with File Viewer PlusFile Viewer Plus is a versatile Windows application designed to open, view, convert, and edit hundreds of file types without needing the original software that created them. Whether you’re dealing with documents, images, archives, audio, video, or specialized formats (CAD, GIS, hex dumps), File Viewer Plus aims to simplify the process of accessing file contents quickly and reliably. This guide covers how to use File Viewer Plus to open practically any file, plus tips for troubleshooting, converting, and integrating it into your workflow.

What File Viewer Plus Does

File Viewer Plus provides a single interface capable of:

Opening hundreds of file formats including Office documents, PDFs, images, audio/video, and many proprietary formats.
Previewing file contents without installing the original application.
Converting files to common formats (e.g., DOCX→PDF, RAW→JPEG, WAV→MP3).
Basic editing for images, text files, and metadata.
Viewing hex and binary data for forensic or development use.
Batch operations for converting or renaming multiple files.

Installing File Viewer Plus

Download the installer from the official website and run it.
Follow the on-screen prompts to install. You may be offered a trial; enterprise licensing is available for multiple users.
Optionally associate common file types with File Viewer Plus during installation so files open in it by default.

Opening Files — Basic Methods

Method 1: Double-click a file associated with File Viewer Plus.
Method 2: Right-click any file → Open with → File Viewer Plus.
Method 3: Launch File Viewer Plus, then drag-and-drop files into its window.
Method 4: Use File → Open… (or Ctrl+O) inside the app to browse and select files.

When you open a file, File Viewer Plus detects its format and displays it in the appropriate viewer — document, image editor, media player, hex viewer, etc.

Opening Unknown or Proprietary File Types

If Windows shows an unknown extension, try renaming the extension to a known one (careful — only if you have reason to suspect the underlying format).
Use File Viewer Plus’s support for file signature detection: the app can often identify a file by its internal signature (magic number) even if the extension is missing or incorrect.
If File Viewer Plus can’t render the file visually, open it in the Hex Viewer to inspect headers which may reveal format identifiers (e.g., %PDF-, PK for ZIP/Office Open XML, RIFF for WAV/AVI).

Viewing Documents (Word, Excel, PDF, TXT)

Documents open in a text/document viewer that preserves formatting for common formats.
For scanned PDFs or images containing text, use OCR (if available in your version) to extract editable text.
Use the page navigation and search features to quickly find content inside long documents.

Opening and Editing Images

File Viewer Plus supports common and RAW camera formats.
Use the built-in image editor for cropping, resizing, color adjustments, and basic retouching.
Save edited images in a different format (e.g., RAW → JPEG) via File → Save As or the Export tool.

Media Files: Audio & Video

The media player supports playback for many popular codecs.
If a file won’t play, the issue is often a missing codec — try converting the file to a more common format (e.g., MKV→MP4) using the Convert feature.
Adjust playback controls, view media metadata, and extract audio where supported.

Archives and Compressed Files

Open ZIP, RAR, 7z, and other archive formats to view contents without extracting.
Extract single files or the entire archive to a folder using the Extract function.
Preview files inside archives before extracting to save time and disk space.

Specialized Formats: CAD, GIS, Hex, and More

CAD and GIS formats may open in a viewer mode with basic pan/zoom; advanced editing is limited.
Use the Hex Viewer for binary inspection, signature searching, or simple analysis of corrupted files.
For forensic needs, File Viewer Plus provides details like file metadata, embedded thumbnails, and timestamps.

Converting Files

Open the file.
Choose File → Save As or Export.
Select the desired target format. Common conversions: DOCX→PDF, PNG→JPEG, WAV→MP3, HEIC→JPEG, RAW→JPEG.
For batch conversions, use the Batch Convert tool and set a destination folder and naming convention.

Tips:

Use lossless formats (PNG, TIFF, WAV) if you need to preserve original quality.
For documents, export to PDF to preserve formatting across systems.

Batch Operations

Batch Convert: select multiple files and convert them all to a single target format.
Batch Rename: rename multiple files using patterns, numbering, or metadata tags.
Useful for photographers exporting many RAW files or for organizations standardizing document formats.

Troubleshooting

If a file fails to open, first confirm its extension and try opening it with the Hex Viewer to inspect headers.
Install necessary codecs if media won’t play; alternatively, convert the file to a more compatible format.
Corrupted files may only show partial content; try extracting what you can or using recovery-specific tools.
If File Viewer Plus displays limited functionality, verify you’re running a version with the required features (some advanced tools may be in paid versions).

Security & Privacy Considerations

Avoid opening files from untrusted sources. Malicious files can contain exploit code, especially documents with macros or unknown executable attachments.
For suspicious files, view them in Hex mode first or open them in a sandboxed environment.
Keep the application updated to benefit from security patches and improved format support.

Tips and Best Practices

Set File Viewer Plus as the default for many common file types to streamline opening multiple formats.
Use batch conversion to maintain consistent file standards across projects.
Keep a small toolkit of complementary utilities: dedicated editors for complex CAD/GIS work, specialized recovery tools, and up-to-date codec packs for media.
Regularly back up important files before converting or editing.

When Not to Use File Viewer Plus

For heavy editing of CAD, GIS, or other professional formats, use the native specialized software.
For advanced image retouching or audio/video production, use full-featured editors (Photoshop, Premiere, Audacity, etc.).
For files requiring execution or installation (program installers, scripts), use appropriate system tools and sandboxing rather than a viewer.

Conclusion

File Viewer Plus is a powerful, convenient tool for opening and working with a wide range of file types without needing the original applications. Its strengths are format coverage, quick previews, conversion capabilities, and lightweight editing. For everyday tasks—inspecting unknown files, converting formats, or quickly viewing content—it’s often faster and simpler than installing multiple specialized programs.
