Deletion of Thumbnails

[outskirter]

If I empty one folder that previously contained images for which XYplorer had created thumbnails, is there an easy way of deleting the thumbnails from the cache? Obviously I wouldn't want to delete all of my thumbnails, otherwise I'd have to regenerate them. Up 'til now I've been opening XYThumbs.txt to figure out which of the thumbnails are no longer valid. Sometimes a lot of them are left behind, and they're kind of awkward to find due to those long hexadecimal file names.

Code: Select all

      $thumbsmod = ""; $thumbssync = "";
      $dat2 = formatlist(folderreport("files", "r", "<xythumbs>", , , "<crlf>"), "f", "<crlf>", "*.dat2");
    if (confirm(quote("OK") . "  to recreate and sync your your XYthumbs.txt file with<crlf>the thumbnnail data files after thumbnail cleanup, or<crlf 2>" . quote("CANCEL") . " to update XYthumb.txt only after cleanup.")) {$sync = "1";}

Thanks, binocular222. I must have missed that post, since I tend to avoid scripting discussions, finding them too technical. I'm using XYplorerFree, anyway, so scripts are not an option. What I had in mind was opening a folder, going to the thumbnail config dialogue, directly or by right-clicking the thumbnail button on the toolbar, and issuing a command to clear the thumbnails for the current folder.

Without script:
- Open \\XYplorer\Data\Thumbnails\XYThumbs.txt
- Find any invalid/empty folder path
- Delete the relevant *.dbits files

Thanks, that's exactly what I've been doing all along.

Honestly, you should consider upgrading to full version.
Scripting brings XY to a totally new level of speed, automation and usability. Catalog is nice too.
