Yes I find it very convenient for reviewing folder contents and moving files about - without having to 'import' or 'export' anything. It's got a good interface for that. Faststone Viewer runs it a close second.
I have occasional periods using, it’s a useful browser if you don't need a catalog, and it integrates well with Photoshop (and other programs).As the title asks.........
If you aren't using Lightroom's cataloguing tools, you might find Bridge more efficient . For starters, no need to import anything before starting work, and the ability to open a file directly in ACR.Never, ever did. Never saw the point. I shoot RAW, develop in Lightroom, do not use the cataloging functions, export the TIFFs to Photoshop and edit there, with the option of going back from Photoshop to CameraRAW if I missed something in Lightroom. Lastly, from the final, edited TIFF I export JPEGs to the desired size(s).
