If this option is on, WinCatalog will automatically adjust the width of the columns in the main grid view in order not to show the horizontal scroll bar. This option may be good if you have three or four columns to display, but it is better to turn this option off for more columns.
If this option is turned on, WinCatalog will use the same icons for files as you see in File Explorer. If this feature is turend off, WinCatalog may use own icons for archives (purple box), video files (film frame), and photos (a photo of dancing girls for JPG files, a photo of a parrot for RAW files). WinCatalog displays custom icons only if it was able to parse the files and grab additional information, it may be considered as a marker if the particular file has doesn't have additional metadata in the catalog.
This option provides the ability to change sort logic by switching between natural and ordinal (i.e. computer) string comparison.
The default option is the natural string comparison (a1→a2→a3→a10→a11→a20→a30→a100). Turning off the natural comparison feature means the sorting decisions are based on simple byte comparisons (a1→a10→a11→a100→a2→a20→a3→a30).
The default sort logic for entries in WinCatalog is to display drives and folders before files, which is the default Windows File Explorer sorting style. Turning this option off will cause displaying folders and files sorted by names ignoring types (Mac OS Finder style).
