After I did a quick look at many of the cloned local copies created by BOX sync, I found there are some patterns on their file name and last modification date:
- They have a file name appendix (n) before the file extension, where n is a number ranging from 1 to 20
- They were last modified on the same day: Feb. 26, 2013
- They are all files. No sub folders were cloned
I could use search in windows 7 to locate all the files satisfying the above patterns with the following search syntax:
filename: "(" kind: NOT folders datemodified:2/26/2013
More than 3000 items were found matching the search criteria. After I verified that they were actually excessive files, I selected all of them and deleted them to clean up the mess.
