In your case the parser won't ever see the else belonging to the if because goto will happily accept everything up to the end of the command. You can see a similar issue when using echo instead of goto.
Also using parentheses will allow you to use the statements directly without having to jump around although I wasn't able to rewrite your code to actually use structured programming techniques; maybe it's too early or it doesn't lend itself well to block structures as the code is right now. If you want to rule out any problems with the else part, try removing the else and place the command on a new line.
Like this:. Back in the days when I did more of this kinda thing, there wasn't. Second, I vaguely remember some kind of bug with testing for the existence of directories. Life would be easier if you could test for the existence of a file in that directory. If there's no file you can be sure of, something to try this used to work up to Win95, IIRC would be to append the device file name NUL to your directory name, e.

You need to make those shares public to everyone. I highly doubt every user has access to your C drive. If you are running this as a login script, do your users have access to that UNC path, including the subfolder that appears to be a specific user's directory?
Why don't you create a share on a server and give everyone access to the share? That way the files are somewhere that can be backed up if necessary and you don't have to give everyone access to your PC.
Thanks for all the replies. I will check what y'all suggested. However, I don't think it is a permissions issue.
Test if Directory exists in Batch file (.cmd)
I have a smaller similar script that used the same path, and executed with no issues as intended. Any guidance would be appreciated. I'm not so sure I have a batch reference book at the house I could look it up in.

Good to know my logic was correct, just not the actual placement of 's in the code itself. Thanks yall! Then you can just look at the share and all that tasty data will be neatly organized and in one place.
