The System Files Thumbnail Database is a binary dataset representing a Windows Thumbs.db file. The file is 34,816 bytes in size and is stored in the archive as a single application‑octet‑stream. It is catalogued as a “Dataset” with no creator or date information, and its access URL is listed as a placeholder. The dataset is part of Drexel University’s holdings and was sourced from the PINAX system.
Background
Thumbs.db is a proprietary Windows system file created automatically by Windows Explorer to cache thumbnail images for folders containing pictures, videos, or other media. The file is generated on the first view of a folder in thumbnail mode and is used to speed subsequent displays. In digital preservation contexts, such files are often archived to preserve the visual appearance of folders as they existed at a particular point in time. The Drexel University archive includes this file as part of a broader effort to preserve system files and their associated metadata, likely for research into file system behavior or for forensic analysis.
Contents
The dataset contains only the raw binary data of the Thumbs.db file. No OCR text or embedded metadata is present; the file is an opaque binary blob. The file is referenced in the archive as “File Thumbs Db” and is associated with the “File Pinax” record that provides descriptive metadata (title, subjects, source). The file itself does not contain human‑readable text, and any thumbnail images are embedded in a proprietary format that requires Windows Explorer or specialized tools to decode.
Scope
The archive holds a single Thumbs.db file, representing thumbnails for a specific set of system files or a folder within the Drexel University environment. The dataset covers the binary representation of the thumbnail cache only; it does not include the original image files, folder structure, or any contextual information about the files for which thumbnails were generated. The scope is limited to the binary cache data and does not extend to the visual content of the thumbnails themselves.
