SQL Server 2008 - RS - Loop of multiple Bulk Inserts

Question

Hi,
I want to import multiple flat files to a table on SQL Server 2008 R2. However, I don't have access to Integration Services to use a foreach loop, so I'm doing the process using T-SQL. Actually, I'm using manually code to which file to introduce the data on
tables. My code are like this:
cREATE TABLE #temporaryTable
    [column1] [varchar](100) NOT NULL,
    [column2 [varchar](100) NOT NULL
BULK
INSERT #temp
FROM 'C:\Teste\testeFile01.txt' 
WITH
FIELDTERMINATOR = ';',
ROWTERMINATOR = '\n',
FIRSTROW = 1
GO
BULK
INSERT #temp
FROM 'C:\Teste\testeFile02.txt' 
WITH
FIELDTERMINATOR = ';',
ROWTERMINATOR = '\n',
FIRSTROW = 1
GO
-------------------------------------------------INSERT INTO dbo.TESTE ( Col_1, Col_2)
Select RTRIM(LTRIM([column1])), RTRIM(LTRIM([column2])) From #temporaryTable
IF EXISTS(SELECT * FROM #temporaryTable) drop table #temporaryTable
The problem is that I have 20 flat files to Insert... Do I have any loop solution in T-SQL to insert all the flat files on same table?
Thanks!

Here is a working sample of powershell script I adopted from internet( I don't have the source handy now).
Import-Module -Name 'SQLPS' -DisableNameChecking
$workdir="C:\temp\test\"
$svrname = "MC\MySQL2014"
Try
#Change default timeout time from 600 to unlimited
$svr = new-object ('Microsoft.SqlServer.Management.Smo.Server') $svrname
$svr.ConnectionContext.StatementTimeout = 0
$table="test1.dbo.myRegions"
#remove the filename column in the target table
$q1 = @"
Use test1;
IF COL_LENGTH('dbo.myRegions','filename') IS NOT NULL
BEGIN
ALTER TABLE test1.dbo.myRegions DROP COLUMN filename;
END
Invoke-Sqlcmd -ServerInstance $svr.Name -Database master -Query $q1
$dt = (get-date).ToString("yyyMMdd")
$formatfilename="$($table)_$($dt).xml"
$destination_formatfilename ="$($workdir)$($formatfilename)"
$cmdformatfile="bcp $table format nul -c -x -f $($destination_formatfilename) -T -t\t -S $($svrname) "
Invoke-Expression $cmdformatfile
#Delay 1 second
Start-Sleep -s 1
$q2 = @"
Alter table test1.dbo.myRegions Add filename varchar(500) Null;
#add the filename column to the target table
Invoke-Sqlcmd -ServerInstance $svr.Name -Database master -Query $q2
$files = Get-ChildItem $workdir
$items = $files | Where-Object {$_.Extension -eq ".txt"}
for ($i=0; $i -lt $items.Count; $i++) {
$strFileName = $items[$i].Name
$strFileNameNoExtension= $items[$i].BaseName
$query = @"
BULK INSERT test1.dbo.myRegions from '$($workdir)$($strFileName)' WITH (FIELDTERMINATOR = '\t', FIRSTROW = 2, FORMATFILE = '$($destination_formatfilename)');
Invoke-Sqlcmd -ServerInstance $svr.Name -Database master -Query $query -querytimeout 65534
#Delay 10 second
Start-Sleep -s 10
# Update the filename column
Invoke-Sqlcmd -ServerInstance $svr.Name -Database master -querytimeout 65534 -Query "Update test1.dbo.myRegions SET filename= '$($strFileName)' WHERE filename is null; "
# Move uploaded file to archive
If ((Test-Path "$($workdir)$($strFileName)") -eq $True) { Move-Item -Path "$($workdir)$($strFileName)" -Destination "$($workdir)Processed\$($strFileNameNoExtension)_$($dt).txt"}
Catch [Exception]
write-host "--$strFileName "$_.Exception.Message
