In Advance way, you need to know FAT32 or NTFS system on how to replicate/trick/encrypt files/folders binaries. There is an easy way from just renaming file name into symbol that explorer would not show it, until encrypt all the data inside and compress it. I know this at the time when I use Windows ME and DOS. Now there is more security features mostly in NTFS that have permissions to read/write file/folder.
Even you use C#, you need to know to program it in unmanaged code because there is no managed library for access/modify low level file system (i think). So master the file system first. You need to trick by your own way, or else, better use the existing application right! In basic way, enumerate and recursive all files inside all folders, open it, encrypt it and replace the data with encrypted. So when other person open the file they can't see the valid content. During the encryption, use the password provided by 'the person who want to encrypt' to encrypt the file. When other user decrypt with wrong password, they also can't see the valid data because the password is wrong. This can be applied to encrypt file only, other user still can see the folder structure and file list. In simple way, you just use WinZip, WinRar or just free AllZip software to zip file/folder and set password to it. On Apr 20, 10:53 pm, "toanmh\\" <[email protected]> wrote: > uhm.
