Adobe Bridge processes and maintains a cache of all audio and video playback files. This improves the performance of playback files because the files are availble for ready access whenever you want to view them later. It is recommended that you regularly clean the old and unused media cache files to optimize the performance. The cache for deleted files is regenerated whenever the source media requires them.
Select one of the following options to set your media cache preferences:
- Do not delete cache files automatically: Select this option to prevent automatic deletion of media cache files. This option is enabled by default.
- Automatically delete cache files older than: Select this option to automatically delete the cache files older than the specified number of days. The default value is 90 days. You can change this to a time period of your preference.
- Automatically delete oldest cache files when cache exceeds: Select this option to automatically delete the old cache files when cache maximum limit reaches to the specified size (in GB). The default size is 10% of the size of the location where the media cache is present.
The automatic deletion of media cache files applies only for the .pek, .cfa, and .ims files that are present within the subdirectory folders, Peak Files and Media Cache Files.
When the age or size preference is enabled, changes take place only after you quit and restart Bridge. On the next application launch, Bridge determines whether the media cache files meet the criteria for deletion, and if so, begins deletion five minutes after launch. This housekeeping then occurs on a weekly basis.
