1. How to put the Recycle Bin and

The Info2 file records the appropriate information for each file that was deleted and placed in the Recycle Bin, such as the drive indicator Dirve designator, the full file name of the original deleted files, the file size, location (path), and the time the file was moved to the Recycle Bin. When a file is moved to the Recycle Bin, the file is renamed to:

d%driveletter%_%indexnumber%_%fileextension%.

d%driveletter%:

"D" represents the disk drive,%driveletter% is placed on the file, and the first disk has its own recycler directory and Info2 file.

%indexnumber%:

Each file or folder that is put into the Recycle Bin is assigned an index number that marks the deletion order, and the larger the index number, the later the deletion. However, when the add-in is emptied or the system restarts, the index number will be assigned from the new start.

%fileextension%:
The name extension of the original file. When a folder is deleted, it has no extension.

For example:

After a file name of Hacker.txt is deleted and placed in the Recycle Bin, the file will be renamed to Dc2.txt, and the file entry can be found in the C:\Recycler\%SID%\INFO2 file.
