- Run command immediate as administrator
- after that use command dir /a and test if you’ll be able to see $RECYCLE.BIN listing
- cd $RECYCLE.BIN to go contained in the listing and use command dir /a

To test customers related to the SID directories you should utilize command wmic useraccount get identify,sid
It is going to record all of the customers related to SID’s. After that duplicate any SID by deciding on and utilizing ctrl C (as properly you should utilize tab key to autocomplete the SID after typing first few characters of SID).
Now, to maneuver into the SID listing:
cd SID (paste the copied worth)
for instance, if the SID listing identify was S-1-5-32
after that use command dir /a to record the parts of that listing you shall see $I and $R information. In sure circumstances, solely $I****** file can be obtainable.
For illustration functions, we’re utilizing information acquired from different programs.
- Now, create a folder and provides a path to repeat the file. Syntax can be file identify “path” ($IABTIOW.doc “D:DesktopTest filesi filesTESTOutput”), you’ll be able to alternatively use the copy command.
- Copy the file/folder identify (whereas contained in the stated listing) and replica to path (the place you want to copy the stated file or folder). The trail might be copied by entering into folder and clicking the handle bar – your file can be copied and the related software program will attempt to open it, however will not have the ability to open (like pictures app for png/jpeg information)

Click on on save. After that, you need to have the ability to see an interface like under:
Then click on parse. It is going to show the file for you if it has efficiently parsed it – the output file can be in .tsv format. You possibly can open the .tsv file with notepad or notepad++. Now, it is possible for you to to see particulars pertaining to the stated $I file.
