You can try Recoll (https://www.lesbonscomptes.com/recoll/pages/index-recoll.html - instant result when searching, but needs indexing first and you might want to donate a little for windows version) or dnGrep (https://dngrep.github.io/ - slower but free and do not need much setup).

NeoFinder. There is a windows version too, but a different name. Great for cataloging/ indexing disks, server volumes, dvds, cds, etc. Can even include a thumbnail photo, text sample, & metadata. Powerful search tools. Easy to use. Not a subscription. Both Mac & Windows versions use same database. Recommended. Mac : https://cdfinder.de/ Windows version: http://www.abemeda.de/.

Not sure this is everything you need, NeoFinder. Https://cdfinder.de/ Is meant for keeping a catalog of removable media so has no expectation of being connected to the source volume to operate. Source: almost 2 years ago

I've found that neither PreRoll Post or YoYotta are very intuitive or useful for cataloguing LTO. I discovered NeoFinder (cdfinder.de) a few years ago and it's incredible and so useful. It creates a catalog file that you easily search or browse similarly to how you would in Finder. It can also create thumbnails and previews for photos/video/audio/etc. It's been bulletproof and I've even used it to catalog... Source: about 2 years ago

I don't know if it's the way I had Bridge set up, but it was desperately slow showing catalogues of images - if it cached the db I didn't notice any speed boost in reading from it that's for sure. If you're on a Mac just looking for images try NeoFinder - I've found it substantially faster! Source: over 2 years ago

On my Mac I use NeoFinder and it's fantastic - fast, extensive and capable of handling a bucketload of file formats. They have a sister product AbeMedia for Windows. I've never used it, but if it's half as good NeoFinder it will be what you're looking for. Source: almost 3 years ago
