What version of the product are you using? On what operating system?

Note: version r412

Please provide any additional information below.

Not sure if the file size is right, either.

Hello,

I have a similar problem on r561 version.

1: Client upload one file "filename1.doc" and name it "file name version 1".

2 few days later, the same client upload the same file with some modifications 
"filename1.doc" and name it "file name version 2".

Then in the list, the first version disappear.
I understand that it comes from the original name of the uploaded files.

The problem is this one:
The Client has not been notified for the conflict filename.

Maybe 2 solutions:
- an automatic rename of filename, if already exists.
- a notification for the client.
