How can I password individual folders in windows Xp?

Answer 1

If your PC is format with NTFS (not FAT32) and if you are using an account with administrator rights, you can right click on any folder and go into the security tab for that folder. You can there change the properties to the folder for the IDs on the computer. You can let your ID read/write, while making the folder restricted to other IDs.
