Documents & Picture folders

Good evening.I have windows 7 home premium desktop.Been trying to sort my picture folder out getting rid of some older ones'Well not getting rid of just moving them to another backup'.
Regarding my picture folder I removed all the photos to an external drive to sort out then moved the ones I wanted to keep back to my picture folder on the C drive,Now this picture folder is also in my documents,Is that correct.
The way I'm looking at it this,If I have 10gb of pictures in my picture folder,And it shows that folder in my documents does that mean that there are 20gb of storage on my C drive?.I tried to delete the picture folder that's in my documents but found that it was a duplicate to the one in my pictures.
Many thanks.

i dont think it does mangoh,
i think it will tell the op the size of each folder ,presumably 10gb each, one could be a copy adding up to 20gb, however it may be a shortcut to the original folder location,
we need to establish whether its a duplicate or a shortcut,

try moving it to your users folder and see if it asks to merge, if its a duplicate copy then it will ask to replace the exsisting files. if so say yes then you will have one copy. 10gb.
