That's the normal display in Windows Explorer. Your files are only stored once, the others link to it. If you delete a file in one place, it will be gone in all.   Best to leave alone.   SECOND ATTEMPT TO POST THIS
Using XP home edition vers 5.1; service pack 3 installed in a dimentions 3000 purchased from Dell in 2004.   There are 2 computer users craig and deb.  I seem to have an identical folder [name=craig1] located in several places.  Here are the 3 locations: 1.  desktop my documents craig1 folder   2.  my computer documents and setting craig my documents craig1 folder 3.  my computer craig's documents craig1 folder I have a backup file that I want to burn to a 700MB CD and the backup is 6GB.  I do not know if the folders are duplicates.  I would like to reduce the size of my backup file.  I moved one file from the craig1 folder in section 1 above to the 'recycle bin' and it also disappeared from the craig1 folder in section 2 above.   Reading Troubleshooting your PC for Dummies [2nd edition 2005] page116, the author, Dan Gookin, states "Don't bother peppering me with questions about why Windows XP has two sets of folders for everything!  That's trouble I would rather not shoot in this chapter."   I do not know if the folders as listed above are the 'normal' folder hierarchy or not.  Can I remove these folders that appear to be duplicates or are these folders a XP built-in redundancy?  Although Mr. Gookin did not want to explore the reasoning for two sets of folders for everything I would appreciate an explaination of how this folder system works.   Thanks.
