3571	Periodic cache purging?	Tristan Croll	Greg Couch	"{{{
The following bug report has been submitted:
Platform:        Linux-3.10.0-1127.13.1.el7.x86_64-x86_64-with-centos-7.8.2003-Core
ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC)
Description
I think it would be wise for ChimeraX to occasionally purge old files from its caches in ~/Downloads. To save disk space (can get quite large for people who look at lots of maps), but more importantly to reduce the instance of people looking at out-of-date versions. Case in point: the models of the SARS-CoV-2 RNA polymerase with the C-terminal register shift. Most of these have now been corrected with new versions in the PDB under the original accession ID, but when I opened them in ChimeraX with ""open {PDB ID}"" I was still getting the old versions until I manually went and deleted them from ~/Downloads/ChimeraX/PDB.
