Bug with using "Replace" on existing file.
User A uploads testdoc.ps1. User B downloads testdoc.ps1, modifies it, and uploads it. User B gets this dialog while uploading:
"A file with this name already exists in this folder. What would you like to do?"
User B clicks "Replace". User B sees the new file. User A sees the old file and is not able to see the new ps1 that User B uploaded. Additionally, other users see only the old file, not the new file User B uploaded.
