I once used a search tool similar to what you describe, it may very well have been the same. It worked in the background, and was a huge resource eater, and created a lot of enormous hidden files. I uninstalled it after a while, the overhead just wasn't worth it.

>the soft you pointed "V" is not instantaneous search file.
>its like all search tools i seen in visual foxpro.it consumes certain time (not negligible many minutes...waiting for result).
>its not free and this is better and light:https://www.nirsoft.net/utils/search_my_files.html
>"Everything" is better filer soft and result is instantaneous.
>I dared the same question: why VFP developers did not work this area of instant file search ? it's surprising,no.I never see a work on this domain in vfp namespace.
>i guess its doable in vfp the only one problem is to find the exact method to update the initial scanned table "online" and gives instantaneous result.

>-scan/endscan directories consumes too time
>-last vfpx works (maybe gofish) ...also
