Instructions below show how to move existing documents stored in the online version of Dropbox over into your MyCase account. Dropbox on your computer will work the same way:
First, select the documents that you would like to move into MyCase, and click "Move"
Then, select the case you would like to move the documents to in MyCase and select "Move."
After the files have been moved into the case folder, they will now be available in MyCase under the "documents" section for your case.
