HP WEBES 6.3 DESTA - Database size

[GuillerminGo]

Hello experts,

I´ve got a windows server 2008 R2 sp1 server running  WEBES 6.3 were OS drive is almost full. I´ve been deleting old files and noticed that the C:\Program Files (x86)\HP\svctools\specific\desta\database\data\base\17397 folder has a 10 GB size, which I would like to decrease as soon as possible in order to improve disk usage.

In this folder I can see, for instance, a file called 17437 (1GB), other file called 1747.1 (1GB) and  another one called 1747.2 (0,6GB). There are more files with a similar behavior and different names.

Since I´m not a WEBES expert, I guess it wouldn't be a good idea to just delete the oldest files from a windows explorer session, right?

I´ve been googling and found another post where an expert tells that this is a known bug fixed in the WEBS 6.1 patch. Bad news are that I have 6.3 version.

Can someone help me or point me in the right way to decrease this folder size?

Thanks in advance

and apologies for my poor english
