General

Auto-delete snapshots that were not opened in last

Deletes temporary snapshots that you have not opened for the specified number of days. Snapshots marked as favorites are excluded when the value is greater than zero. Set the value to 0 to delete all temporary snapshots on exit, including favorites. This option is disabled by default; the initial threshold is 30 days.

Auto-delete the oldest snapshots so that the storage size never exceeds

Limits temporary snapshot storage to the specified size in GB. When the limit is exceeded, cleanup deletes snapshots in order of last access, starting with those you have not opened for the longest time. Favorites are excluded when the limit is greater than zero, so they can prevent cleanup from reaching the limit. Set the value to 0 to delete all temporary snapshots on exit, including favorites. This option is disabled by default; the initial limit is 100 GB.

Auto-delete the oldest monitoring snapshots so that their number does not exceed

Keeps the specified number of most recently accessed temporary monitoring snapshots and deletes older ones. Favorites are excluded from both deletion and the count. Set the value to 0 to delete all non-favorite temporary monitoring snapshots. Cleanup runs when a monitoring snapshot is added and on exit. This option is enabled by default with a limit of five snapshots.

Open timeline profiling snapshots in Visual Studio by default
