Sometimes my development databases use to much space that is not required. Most of my dev sqlserver databaeses are not used – kep for future reference only. Thre is way to keep their size to minimum:
backup log MyDbName with truncate_only dbcc shrinkfile(MyDbName_log,2)
Second sql statement uses database transaction log filename, it may have different name. You can check it’s name on database properties dialog -> Files.
