FindFilesInFolder

Introduced

v5.0

Description

Searches a folder for files with names that match a regular expression. The search is not recursive: only the specified folder is searched. On Windows, the search is case-insensitive; on Linux, it is case-sensitive.

Scripting Syntax

oArray = FindFilesInFolder( Directory, [RegularExpression], [FindAllMatches], [ReturnFullPath] );

Return Value

By default, FindFilesInFolder returns the name of the first file that matches the regular expression. If no match is found, an empty string is returned.

If FindAllMatches is True, FindFilesInFolder returns a JScript Array that contains the names of all the files that match. The VBScript example on this page shows how to handle this JScript array in VBScript.

Parameters

Parameter Type Description
Directory String Full path of the folder to search
RegularExpression String A correctly-formed regular expression

Default Value: ".*", which matches all files

FindAllMatches Boolean True to return all files that match the regular expression. False to return only the first file that matches.

Default Value: false

ReturnFullPath Boolean True to return the full path name of the files that match. False to return only the file name.

Default Value: true

Examples

1. JScript Example

/*

	Example that shows how to get all the .scntoc files in the 

	current project

*/

var strTestFolder = XSIUtils.BuildPath( Application.InstallationPath( siProjectPath ), "Scenes" ) ;

/*

	This regular expression matches any string

	that ends with ".scntoc". This is the same

	as the command-line wildcard "*.scntoc".

*/

var regularExpressionToMatch = ".*\.scntoc$" ;

var aTocFiles = FindFilesInFolder( 

			strTestFolder, 

			regularExpressionToMatch, 

			true, 			// Find all matches

			false ) ;		// Return file name only

					

				

strMsg = "\nFound the following .scntoc files in " + strTestFolder + "\n" ;

	

for ( var i = 0 ; i < aTocFiles.length ; i++ )

{

	strMsg += aTocFiles[i] + "\n" ;

}

Application.LogMessage( strMsg ) ;

2. VBScript Example

'

'	Example that shows how to get the list of .scntoc files

'

'in a folder.

dim strTestFolder, strTocFiles, strMsg, aTocFiles, regularExpressionToMatch

strTestFolder = XSIUtils.BuildPath( Application.InstallationPath( siProjectPath ),"Scenes" ) 

' This regular expression matches any string

' that ends with ".scntoc". This is the same

' as the command-line wildcard "*.scntoc".

regularExpressionToMatch = ".*\.scntoc$" 

'The command returns a JScript array, which appears as a 

'comma-delimited string in VBScript

strTocFiles = FindFilesInFolder( _

			strTestFolder, _

			regularExpressionToMatch, _

			true, 		 _	

			false )

'It is easy to convert it to a VBScript array

aTocFiles = split( strTocFiles, "," )

									

strMsg = vbCrLf & "Found the following .scntoc files in " & strTestFolder & vbCrLf	

for i = 0 to Ubound( aTocFiles )

	strMsg = strMsg & aTocFiles(i) & vbCrLf 

next

Application.LogMessage strMsg

3. JScript Example

/*

	This example shows how the FindFilesInFolder command could

	be implemented in JScript as a self-installed custom command.  

	The custom command uses the FileSystemObject class and

	JScript Regular Expression support
