Opens and Save Files Utility

OpenSaveFilesView is a popular, lightweight freeware utility developed by NirSoft. It is specifically designed to uncover and display a comprehensive history of files that have been opened or saved on a Windows computer using the operating system’s standard Open/Save dialog boxes.

This utility acts as a forensic or reminder tool, extracting information hidden deep within the Windows Registry that tracks user activity. ⚙️ How the Utility Works

Every time you use an application (like Notepad, MS Word, or an image editor) and open or save a file via the program’s pop-up window interface, Windows tracks that interaction. OpenSaveFilesView targets two specific Registry keys known as the Most Recently Used (MRU) lists to compile its data:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePidlMRU

Note: The utility will only show files processed through these standard dialog boxes. It will not list files or programs that you double-clicked directly within File Explorer or executed via the command line. 📊 Information Captured by the Tool

For every file detected in the Registry history, OpenSaveFilesView displays a detailed breakdown across several data columns:

Filename & Extension: The exact title and format (e.g., .docx, .pdf, .png) of the file.

File Path: The precise folder location where the file lives or lived.

Order: A sequential numbering indicating the chronological order in which files of that specific extension were accessed.

Open Time: The exact timestamp of when the file was last opened (historically available for the most recent file of each format).

File Creation / Modification Time: System data showing when the file itself was first generated or last updated.

File Size & Attributes: The data size of the file alongside typical Windows permission tags (like Read-Only or Hidden). 🛠️ Core Features and Capabilities
