Preview pane in Windows 10 file explore will not show a preview of a PDF file if the filename has a "#" hashtag in it. We use PDF file names with a hashtags in them for purchase requisition tracking. Example: PR#1234. If we remove the hashtag it will show in the preview pane. This seems to have changed recently. Employees are reporting that Preview was working with files that had a hashtag in them previously. The exact change point is unknown. We checked other file types shuch as MS Excel and it was not a problem. Excel will show in the preview pane with a hashtag in the file name.
Anyone got a way to make this work without renaming thousands of files?
I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Acrobat forum so that proper help can be offered.
