I am trying to get the latest file from ftp.File format is like this-
abc_xx_123_a_b_c.exe
abc_xx_124_a_b_c.exe
abc_xx_125_a_b_c.exe
abc_xx_126_a_b_c.exe

There is no datestamp in the filename but number like 126 determine the latest file.So here abc_TEST_126_a_b_c.exe
is greater than abc_TEST_123_a_b_c.exe
and abc_xx_123_a_b_c.exe is the oldest file.

How would I accomplish this and I would prefer without doing script task.Thanks in advance.

Add a for each loop to loop through the files and add filenames received to a table. Then add a logic to get max of number value within filename, something like


SELECT TOP 1 filename
FROM Table
ORDER BY LEFT(STUFF(filename,1,PATINDEX('%[0-9]%',filename)-1,''),CHARINDEX('_',STUFF(filename,1,PATINDEX('%[0-9]%',filename)-1,''))-1)*1 DESC

then in a file system task pass the filename got above as source to move file to wherever you want
