Welcome to Eight Forums.

I assume you have a Window 7 ISO with this install.wim in it. You can use DISM to manipulate the install.wim file. Are you trying to make a bootable USB to install this Windows 7? Are you failing because the install.wim is larger than the 4GB file size limit of Fat32?

While you could use DISM to compress the install.wim to an install.esd, it's a complicated process and there's no guarantee that the install.esd you make would be less than 4GB.

The simplest solution is to split the install.wim into multiple .swm files, each less than 4GB. Place these in the sources folder instead of the single .wim. Setup doesn't care if there is a single install.wim or a set of install.swm, install2.swm, etc. files. It can install Windows from either.

Instructions are in the link below, use /Filesize:4000 for files that will be copied to a Fat32 USB.

To make a bootable install USB, mount the ISO, copy all the files and folders except for the install.wim to a large enough USB formatted as Fat32. Copy your split .swm files to the Sources folder on the USB instead of the (too large) original install.wim. Use Disk Management to mark the USB's partition as Active. You can now boot from this USB to install Windows 7.

how can i compress the windows 7 using ESD method

DISM cannot convert a .wim to a .esd (or a .esd to a .wim) in one go. What you can do is export a single edition at a time (Home, Pro, etc.) by specifying its index number. You have repeat this for each edition you need to export to the .esd. This tutorial shows how to export from an esd to a wim, just swap the file extensions to do it the other way round. The command you need would look like this.

dism /Export-Image /SourceImageFile:D:\Sources\install.wim /SourceIndex:1 /DestinationImageFile:D:\Sources\install.esd /Compress:Max /CheckIntegrity
