I created a copy of that folder and copied the files over one at a time (thankfully there were only a few files in that folder), and tested opening with Explorer with each file I added. Every time it opened correctly until I got to this guy:<\/p>\n<p><a href=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image4.png\"><img loading=\"lazy\" decoding=\"async\" style=\"padding-left: 0px;padding-right: 0px;padding-top: 0px;border: 0px\" title=\"image\" src=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image_thumb4.png\" alt=\"image\" width=\"308\" height=\"108\" border=\"0\" \/><\/a><\/p>\n<p>As soon as I removed it from that folder \u2013 presto! Problem solved! Armed with the <strong><em>how<\/em><\/strong> but not the <strong><em>why<\/em><\/strong> I took the battle to the Googles\u2026 and I came across a forum post that mentioned illegal characters in the file name, so I started to suspect that this is where the problem was. My first thought was that it was the plus sign, but that wasn&#8217;t it, and it wasn&#8217;t file length either (260 characters allowed in the complete URL for the file or folder &#8211; just in case you were wondering). After trying variations of file length and removing characters to no avail, I copied the URL to the file and pasted it into Notepad. Turns out that one of the spaces in the filename had an ascii 255 character that looked like a space, but wasn&#8217;t.<\/p>\n<p><a href=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image5.png\"><img loading=\"lazy\" decoding=\"async\" style=\"padding-left: 0px;padding-right: 0px;padding-top: 0px;border: 0px\" title=\"image\" src=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image_thumb5.png\" alt=\"image\" width=\"314\" height=\"37\" border=\"0\" \/><\/a><\/p>\n<p>I renamed the file and removed the offending space and put it back in again, and now it was properly rendered in the URL as <strong>%20, <\/strong><\/p>\n<p><a href=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image6.png\"><img loading=\"lazy\" decoding=\"async\" style=\"padding-left: 0px;padding-right: 0px;padding-top: 0px;border: 0px\" title=\"image\" src=\"\/wp-content\/uploads\/brainlitter\/2011\/12\/image_thumb6.png\" alt=\"image\" width=\"302\" height=\"34\" border=\"0\" \/><\/a><\/p>\n<p>and now <strong>Open in Explorer <\/strong>works as it should in that folder.
