Hi,
Thank you for posting in Symantec community.
Q. Which is almost 10gb in size. and contains around 24 folders. The date on some of thes folders is from 2012. Do i need to keep all these?
--> Do not delete files manually, those will re-populate again. 10 GB size is acceptable size. In case if you think old files are stuck can run SEPM repair.
If we checked system requirements, followings are the recommendations for disk space:
Small Business Edition: 16 GB available minimum; 100 GB available recommended.
Enterprise version: 16 GB available minimum (100 GB recommended) for the management server; 40 GB available minimum (200 GB recommended) for the management server and a locally installed database.

However, in the latest version of SEP 12.1 RU5 new feature is introduced, Content Storage Optimization feature:
As part of the upgrade to SEPM 12.1 RU5, the SEPM converts all of the content from full definitions to delta definitions. This process is resource intensive and may take an extended period of time. After this process is completed, the SEPM will use significantly less disk space.
In a typical enterprise setup where 30 content revisions stored, the SEPM upgrade process must reduce 55GB of full content to under 2GB of delta content. This process requires significant resources to complete and is impacted by the performance of any available CPUs, CPU cores (physical/logical/hyperthreading), memory, and disks (I/O). On a server that performs multiple roles, stores larger numbers of content, or is otherwise resource constrained, this process may take a longer duration to complete.
