Features: - Fast file and folder search across all indexed drives - Support for wildcards and boolean operators - Multiple sort options (name, path, size, dates) - Case-sensitive and whole word matching - Regular expression support - Path matching Search Syntax Guide: 1. Basic Operators: - space: AND operator - |: OR operator - !: NOT operator - < >: Grouping - " ": Search for an exact phrase 2. Wildcards: - *: Matches zero or more characters - ?: Matches exactly one character Note: Wildcards match the whole filename by default. Disable Match whole filename to match wildcards anywhere. 3. Functions: Size and Count: - size:<size>[kb|mb|gb]: Search by file size - count:<max>: Limit number of results - childcount:<count>: Folders with specific number of children - childfilecount:<count>: Folders with specific number of files - childfoldercount:<count>: Folders with specific number of subfolders - len:<length>: Match filename length Dates: - datemodified:<date>, dm:<date>: Modified date - dateaccessed:<date>, da:<date>: Access date - datecreated:<date>, dc:<date>: Creation date - daterun:<date>, dr:<date>: Last run date - recentchange:<date>, rc:<date>: Recently changed date Date formats: YYYY[-MM[-DD[Thh[:mm[:ss[.sss]]]]]] or today, yesterday, lastweek, etc. File Attributes and Types: - attrib:<attributes>, attributes:<attributes>: Search by file attributes (A:Archive, H:Hidden, S:System, etc.) - type:<type>: Search by file type - ext:<list>: Search by semicolon-separated extensions Path and Name: - path:<path>: Search in specific path - parent:<path>, infolder:<path>, nosubfolders:<path>: Search in path excluding subfolders - startwith:<text>: Files starting with text - endwith:<text>: Files ending with text - child:<filename>: Folders containing specific child - depth:<count>, parents:<count>: Files at specific folder depth - root: Files with no parent folder - shell:<name>: Search in known shell folders Duplicates and Lists: - dupe, namepartdupe, attribdupe, dadupe, dcdupe, dmdupe, sizedupe: Find duplicates - filelist:<list>: Search pipe-separated (|) file list - filelistfilename:<filename>: Search files from list file - frn:<frnlist>: Search by File Reference Numbers - fsi:<index>: Search by file system index - empty: Find empty folders 4. Function Syntax: - function:value: Equal to value - function:<=value: Less than or equal - function:<value: Less than - function:=value: Equal to - function:>value: Greater than - function:>=value: Greater than or equal - function:start..end: Range of values - function:start-end: Range of values 5. Modifiers: - case:, nocase:: Enable/disable case sensitivity - file:, folder:: Match only files or folders - path:, nopath:: Match full path or filename only - regex:, noregex:: Enable/disable regex - wfn:, nowfn:: Match whole filename or anywhere - wholeword:, ww:: Match whole words only - wildcards:, nowildcards:: Enable/disable wildcards Examples: 1.
