The functionality of this app and the app "File Content Explorer" is identical, but this app is technically based on WinUI 3 and the app "File Content Explorer" on UWP. Unlike a UWP app, this app can be started with administrator privileges and multiple instances of this app can run simultaneously. For this, the app requires all the permissions of a Win32 application during installation. Despite minor differences, the screenshots are from the app "File Content Explorer". This app is a combination of a simple file manager and a file viewer with a practical preview function for all common file types. In addition to the overview, the file management functions also work in the detail view in order to ensure the most efficient file management possible. No installed programs are required to display the supported file types and all files can be viewed without risk, as no macros or scripts are executed. The use of separate programs for file operations and file viewing can be inefficient when managing a large number of files due to frequent program changes and the preview functions and thumbnails of Windows Explorer have several limitations in contrast to this app. Windows Explorer only shows the thumbnails and previews for harmless files and requires certain settings and installed programs for this. For example, Windows Explorer only shows Office files as a preview if they do not come from other computers, do not contain macros and a suitable Office program is installed, while thumbnails are only displayed for files that are already locally saved. On the other hand, this app already shows as much of the content of the supported file types as possible in the overview and the delay-free preview, so that the detail view usually only has to be opened for a complete display of the content. The overview consists of two halves in which all items of a selected folder are displayed and between which various file operations can be carried out. Depending on the settings and the number of files, a flat view can be opened in one half via the context menu in which all files in the subfolders are displayed instead of the folders. Unsupported file types are displayed in the overview with their icon or as mere characters, while they are first displayed in hex format in the detail view, which can be opened by double-clicking, the context menu or the enter key. In the detail view you can switch between content display and hex format for supported file types and each file can also be opened with the linked program. The overview can also be filtered according to various criteria, whereby any number of filters can be created and saved. In addition to the usual keyboard navigation and support of the delete key in the overview and the detail view, it is possible to search for items in the overview by their initial letter and use the backspace key to exit all views. For file management, this app supports the file operations copy, mirror, delete, compare, and split. When mirroring, only new and modified files are copied to the target folder, where unnecessary files can also be deleted to keep it synchronized with the source folder. Additionally, SHA-256 hashes of files and folders can be created and compared via the context menu. When renaming a file, the file extension can be checked or suggested based on the content. The integrated file viewer can display and play text files, image files, video files, audio files, Office files in OOXML or ODF format, PDF files, RTF files, ZIP files, and folders. Filter criteria for each filter can be defined as content type, a search text or regular expression for the content of text and Office files, four OR-linked file patterns, a file size range, a date range, and two OR-linked folder patterns. Filtering by content also displays the corresponding results in the detailed view. For OOXML files from Word, PowerPoint, and Excel, display as plain text or with basic formatting is supported. For ODF files, only display as plain text without formatting is possible. Text files or Office files in text format can be compared line by line, either unchanged or in synchronized form by automatically inserting blank lines for maximum matching, and the differences can be highlighted. Due to specific app restrictions, this app does not display files that have the System or Hidden file attribute set, and no folders that have the Hidden file attribute set. However, these file attributes are usually set only for various files or folders of Windows or some programs. In addition, these elements are not included in any file operations. These restrictions also apply to the shortcut files with the file extension lnk and url. The only exception is deleting a folder, where corresponding items are also deleted.
