Is there a size limit on catalogs, or how much data can WhereIsIt handle? Is there a slow down when working with large catalogs?
The only limit are your system capabilities and some common sense practical usage. The theoretical limit per single catalog file is 2 GB in size, which is the equivalent of about 70 million files and folders with moderate use of descriptions, or about 120 million, if using catalog compression in version 3 (not recommended). Practical limits are lower than that though, operations like searching or saving on such large files are likely to take too long to be still comfortable to use. The usual size of catalog files would be up to a couple hundred MB or so, however that’s your call. There are a few customers who have their catalogs over 1.5 GB in size (a disk image of corporate network server), and are still satisfied with performance. That’s a bit extreme though, a wouldn’t recommend pushing it that far. In any case, no one says that you must have just one catalog – in fact you don’t usually work with such large collections. WhereIsIt can have opened multiple catalogs at once and use the
