Hides your valuable files by using different methods of your choosing, here is a copy of the readme explaining each method, and in accordance, Binary File Addition is the best.
Here is a description of each method:
1. hideme - uses C++ and batch to use system protection API (both attribute changes and DWM modification).
2. Binary File Addition - Basically copies all binary info from one file into the destination file, keeping its information IN disguise in the other file.
3. NTFS Alternate File Stream - Simple, it groups the files into one, leaving the embeder file visible and the embedee invisible, if you drag and drop the embeder file into a drive in a different file system format (like FAT32, EXT4) both files will show, so if that will ever happen, binary is you best bet.
