A software with one-click layout for up to four directory panes, offering easy multiple file renaming, a powerful thumbnail viewer and editor for pictures and video, navigation history, directory synchronization, file cataloging, start-up program management and custom looks.

One of the great things about One Cat File Manager is that it is quite easy to get started, thanks to the similarity with the standard Windows interface. However, there is one big difference: the icons in the main toolbar that control the layout - this feature allows you to change between a single file pane and as many as four panes with ease.
With One Cat File Manager, browsing, copying, and moving files around is a breeze. The integrated thumbnail image viewer with multiple thumbnail layouts, slideshows, effects, and image processing provides most of what you require to browse and edit your image collection. You can also view any file display in this mode, which allows your images, video, or even slide shows to play along as you work on your files.
In addition, version 4 of One Cat File Manager has some impressive features that make it even better. For example, the software provides file analysis features that show statistics such as size or type distributions viewable in a spreadsheet or charts. Renaming multiple files has always been a real pain while using Windows, but this is no longer an issue with One Cat File Manager as the software allows you to rename an entire set of files with a preview of how they will turn out.
What's more, version 4 extends the renaming capabilities to include prefixes, suffixes, and procedural renaming. Procedural renaming provides you with the ability to rename files completely from scratch all at once according to various rule sets. In short, trying One Cat File Manager is addictive!
