Your expression does not match a fully qualified domain name such as this. "\\Server.Domain\Folder\

just wanted to thank you for the expression... I have modified it a bit though and wanted to share. 1) I wanted the share portion and the path portion to be captured into registers. (ie. (\\server\share)(\folder1\folder2\file.exe) 2) I needed to allow hidden shares (ie. \\server\share$). 3) Trailing slashes are now allowed. (ie. \\server\share$\folder\) 4)I noticed that some valid folder name characters were not allowed in the current expression and so rather than adding the valid characters, I have modified it to restrict the use of non-valid characters. (ie. \\server\share$\folder.1\folder.2\!folder 3\) ^(\\\\[\w-]+\\[^\\/:*?<>|""]+)((?:\\[^\\/:*?<>|""]+)*\\?)$ one thing I thought about (but decided it was unimportant for my project) was specifically capturing the file name to another register, but there would be no way to distinguish between a folder name and a file with no extension.

Its a very nice expression but it seems to be working only with share names that have no spaces how about modifying it to allow spaces, for exampe \\myserver\my share\my folder\my file.txt It will be a great help for me.
