Dear all,

I want to free some space in my C: unit. To my surprise I have discovered some across-related files (5 GB in total), which seem to be old, but I am afraid to delete something still needed.

These files are in my user folder | AppData | Roaming | across | databases

And most of their names look like

across_OLIVER-PC_16h02m_24_10_2014.mdf and so on...

The biggest is more than 1 GB! Do I really need these files? What are they for? The one of the example is one year old, and since I work connected to a server, I don't think they are useful anymore.

Does anybody know what are these files needed for?

Your help will be very much appreciated,

I am not sure, but.... Jul 17, 2015

..... crossTank is your TM (heavy) and the other one looks like a common file, but the one who really can answer this question is yourself. In some point in time, you created them, so how does anybody else knows if you still need them or not?

I would suggest, try to open them and have a look what is 'inside'.

That could be right... Jul 18, 2015

but one of the main problems of across is its lack of transparency.

I only use across server-based, so I "Retrieve tasks" and "Deliver tasks", the rest is out of my reach. In fact, the AppData folder is invisible in Explorer by default, so that you could have those files in your drive for ages without noticing.

I have tried to execute the files, which are "SQL Server Database Transaction Log Files" and "SQL Server DB Primary Data File", but, as I suspected, nothing happens.

They really look like old files with no use, but still I would like to know if that could have a negative effect in the software.

Thank you for your answer, Robert!

Have a nice weekend
