You can defragment endpoint disks using below script,

import os;
defragmentation=os.popen(‘defrag.exe /C’).read()
print(defragmentation);

Note: NO STDOUT text. Check success or failure state of script.

Hi all,

Please refer updated procedure for disk defragmentation,


import os; 
import ctypes
class disable_file_system_redirection:
    _disable = ctypes.windll.kernel32.Wow64DisableWow64FsRedirection
    _revert = ctypes.windll.kernel32.Wow64RevertWow64FsRedirection
    def __enter__(self):
        self.old_value = ctypes.c_long()
        self.success = self._disable(ctypes.byref(self.old_value))
    def __exit__(self, type, value, traceback):
        if self.success:
            self._revert(self.old_value)

with disable_file_system_redirection():
    out=os.popen('defrag.exe /C').read()
    print(out);

Hi @mkannan,

Does this script work as well in SSD?

Thank you,
Alfie

Hi @alfie013

Yes, it will support SSD hard disk if windows ‘defrag.exe’ tool works with SSD.

Thanks

Hi @mkannan,

Can you please add on the script to check first the HDD/ssd before defragging it. For example, I run the Analyze and if the result is 0 meaning no need to defrag else if 1 or above it will defrag the HDD/SSD.

Thank you,
Alfie

Hi @alfie013

We will analyze and let you know the update soon.

Thank you.

Hi,

Please use the script to perform defragmentation after analysis of fragments.

Note:
The script analyzes all the Drives for fragments. Checks whether the fragmented rate is 0% then the script prints only analyzed report otherwise, the script performs complete defragmentation operation and prints the report
