Anyone knows if I can delete the files in that folder without any problems and when how and why they are created. Accumulated 4.5 GB in there :-)
They are all rather fresh. They simply contain Telerik.Sitefinity.dll each with 24 MB but I have 190 of them in the past 3 days.
To me it seems every time I start the sitefinity manager it will create one folder with every project in that version. I have been updating some sites. So on every update it will create one of these folders and probably not clean it out later.
Started Sitefinity 7.0 manger and got one folder for each site that I have already updated, Closed and exit the sitefnity manager and started it again and bang, doubled that amount.
