Is there any way I can make a file in normal xp "Advanced Hidden" like you can in an ISO file with UltraISO?

Thanks,

MrChris

Yes, but using a different method. It's called < ADS (Alternate Data Streams) >, a feature of the < NTFS file system > which Windows XP is installed on. Windows XP also supports the older and slower < FAT32 files system >, which in you might have Windows installed on that - if so you cannot use ADS and other important NTFS features (and I strogly suggest you < reformat your system drive > and reinstall Windows on an NTFS file system.

ADS allows you to save a few version of a file under the same name. For example, I could have a file name C:\Report.txt and save another file under a different “stream”, or version, under C:\Report.txt:HiddenVersion

The file Report.txt will be visible and can be opened, but the file Report.txt:HiddenVersion is not visible – not in windows explorer and not in the command prompt (cmd.exe).

You can try it for yourself:

1. Click Start >> Run…
2. Type notepad C:\myfile.txt
3. Press OK
4. Notepad open up with the regular unhidden file myfile.txt. Type something in it and save it.
5. Go to Run again, but this time type notepad C:\myfile.txt:mysecret
6. Notepad will ask you weather to create myfile.txt:mysecret or not. Click Yes.
7. This is a new file, but under the same filename (but with a stream name of mysecret). Type something different in it and save it.
8. Now try opening myfile.txt the familiar way, by going to My Computer >> C: >> Double-click myfile.txt
9. You will see that the file that was open was the first one you save, the unhidden one. You will also notice that the second, hidden file you saved is no where to be seen.
10. To open your hidden file, go back to Run and type notepad C:\myfile.txt:mysecret and you will be able to see your hidden file again.

You can create as many alternate streams as you wish. When you delete, rename, or move the unhidden file, it affects all the streams (they will all be deleted, renamed or moved).
