File and Folder Encryption on Windows XP

By godzillex ·
Hi,

I'm new to Windows XP, and need help with the following questions:

1. On Windows XP, when copying an encrypted file (from an encrypted folder) and placing it in another non-encrypted folder, does the file gets automatically decrypted (since it's no longer in an encrypted folder)?

2. What happens when the same encrypted file gets copied into a floppy disk? Can someone else read the file from floppy on their machine without knowing how to decrypt it?

3. I recall letting Windows XP encrypt my entire C: drive, but now do not recall on which configuration screen I did this! Does anyone know how I may undo this act?

4. How secure is the XP's built-in encryption?

5. Does anyone know how to encrypt Windows TEMP folders (they seem to be always locked by the system)?

Thanks!

If you copy the file to another location on a ntfs file system it will keep the encryption, but if it is copied to a drive with a fat file system it will loose its encryption.

2. What happens when the same encrypted file gets copied into a floppy disk? Can someone else read the file from floppy on their machine without knowing how to decrypt it?
Only the user who set it to encrypt will be allowed to open and edit the file. Anyone else who tries to open, copy, move, or rename your encrypted file will get an access denied mesage.

3. I recall letting Windows XP encrypt my entire C: drive, but now do not recall on which configuration screen I did this! Does anyone know how I may undo this act?
System files cannot be encrypted. So this cannot be possible. You may of compressed the drive tho.

4. How secure is the XP's built-in encryption? Pretty secure, I guess really depends on what your wanting to do.

5. Does anyone know how to encrypt Windows TEMP folders (they seem to be always locked by the system)?
I dont know if it is possible to encrypt the temp folders, but why would you want to in the first place?
