How to check particular prefix files exist or not inside directory

ganeshK — Tue, 25 Jan 2022 06:33:53 GMT

Hi,

I wanted to check particular prefix files are exist inside directory or not. If exist i want to perform some operation.

Tried with tFileexist -> It is checking only fully qualified file name. I want to check file exist or not with particluar prefix.

Tried with tFileList -> It is listing all files taking too much time. Simply i wanted to check is there any file exist with particular prefix.

Example:

Folder contains 1_filename1, 1_filename2, 1_filename3 , 2_filename1, 2_filename2, 2_filename3 etc..

I want to check is there any file exist with 2_*

Regards,

Ganesh.R

Hi maybe you can do this :

in a tJava

-- in advanced settings :

import java.io.File;

-- in basic settings:

File dir = new File("here your directory path");

Boolean fileExist = (dir.listFiles(file -> file.getName().matches("^2_.*"))).length>0;

send me love and kudos
