    This is normal. The PerfectBrowseCache holds the rendered previews for all the photos in the folders you have Cataloged. It will grow to be as large as needed. This article may help. Catalogs and Caches - ON1 Photo RAW 2022 & ON1 PHOTO RAW 2021

    Thank you Brian.

    Several factors come into play when deciding on Preview size for catalogued folders (as mentioned in the article referred to), but personally I have found that Medium size preview option has minimal impact on load times (as compared to Standard) but with much less use of space.

    Admittedly, I have a relatively small library and am not a high power user but might be worth experimenting with something other than Standard if space becomes an issue.
