I deployed the OS through SCCM by using the hardlink and store data in local drives

During the deployment is create a folder "c:\locaStatedata"  based tasksequence config

So far the migration work fine.

Our concern to cleanup unnessary folder in drive c:\  and I want to delete the "c:\locaStatedata" which is the hardlink info

May I know what is effect if I delete the mention  folder ?  or what is approach  to delete the mention folder

Please advise

You have to delete the folder.

This can be done properly via the usmtutils.exe utility included with USMT 4. To properly remove the State Store, run the command:

usmtutils.exe /rd <Path_to_State_Store>

where <Path_to_State_Store> is the path as specified in the OSDStateStorePath variable via the "Set Local State Location" task (without the brackets <>).

Not deleting the State Store can cause the following problems:

• If an administrator tries to access the State Store, it may change the permissions of all of the user files in the State Store to the administrator's permissions. This may cause users not to be able to access their files and they may receive "Access Denied" error messages. For this reason it is recommended that an administrator not try to access the State Store directly.
• A user deleting files in their profile will not cause the actual file to be deleted since a second link exists to the file in the State Store. Although the user will no longer see the file in their profile, the link to the file will still exist in the State Store, and disk space will not be freed up.
• In Step 18 (Method 1) and Step 9 (Method 2), the option "Continue on Error" is disabled. This option is originally enabled because with USMT 3, USMT 3 could report a lot of false positive errors, causing the task to un-necessarily fail. However this has been improved in USMT 4 and this situation should rarely happen with USMT 4.
  If the option is left checked and the USMT 4 state capture fails for some reason, the Task Sequence will continue and eventually wipe the drive at the "Apply Operating System Image"/"Apply Operating System" task, causing all user files and settings to be deleted and lost. For this reason it is safer to leave this option unchecked when using USMT 4. Leaving the option unchecked will cause the Task Sequence to fail in the event that users' files are not captured successfully, which is a desired outcome.
• In Steps 18 and 21 (Method 1) and Steps 9 and 13 (Method 2), the option "Enable verbose logging" is enabled. This is optional, but it is advisable to leave this option enabled to help troubleshoot USMT 4 capture and restore failures. Enabling verbose logging will cause the capture and restore tasks to take a bit longer, but will the add the benefit of having more detailed logs to help resolve problems.
• The tasks "Request State Store" and "Release State Store" are not needed in the Task Sequences that performs local capture with hardlinking because these tasks are only used when a State Migration Point (SMP) is being used. An SMP is only used when the State Store is saved to a network location. When using hardlinking, the State Store is always saved to the local hard drive and an SMP is not used.
• In Steps 17 and 20 (Method 1) and Steps 8 and 12 (Method 2), please make sure to make the distinction between the variables specified in the tasks "Set USMT Additional Capture Options" and "Set USMT Additional Restore Options". The variables have similar names but they are different. One is OSDMigrateAdditionalCaptureOptionsand the other is OSDMigrateAdditionalRestoreOptions.
