I had a look at previous QlikCommunity discussions on this topic and it seems that it is only possible with services like web server, QVS et cetera.
What I would recommend is have a a vb script run on your qvw after reload to move the file from its current location to the location you want.
Check out this link for options on the type of move you want to do. Let me know if you come right mate
Hi , We can't change the location for .qvw logfile which was created by reload task. The workaround, please uncheck the Timestamp in Logfile Name in the Document Properties --> General. So we have only one Log file in the qvw folder.
There is another option, create a batch file, to move all the log files form qvw folder into another location.
