2.Directory browser

This part shows files and folders of the partition whose sectors are being edited.

Double click the folder to visit its files and click the mark ".." to return to parent directory.


This area interprets current cursor. When legal and valid data is entered the edit box, the interpreter will automatically convert it to corresponding hex value and write it to area ④, which saves manually conversion. Here are the types it can interpret:

2) GUID: GUID (Global Unique Identifier) is a 128-bit number identifier produced by algorithm.
3) Time and date: C Date is a 32-bit integer value, representing seconds since January 1, 1970; DOS Date is used by several DOS function calls and by all FAT file systems, and the lower word determines the time, the upper word the data; FILETIME is a 64-bit integer value representing the number of 100-nanosecond intervals since January 1, 1601. Used by the Win32 API.
