Try looking at your filenames, although Windows, OSX, Linux, etc. can handle 'funky' filenames, some apps can't especially if they utilize the shell interface (maybe behind the scenes, so you might not realize it). Things like spaces, special characters, more than one dot/period, etc. in the folder/file name might be causing the error.
I'm so old school that I still NEVER use spaces in my folder/filenames (I use underscore in folder names and dash in filenames for 'spaces'), and only a-z A-Z and 0-9 in my folder and file names.
This practice derives from when spaces and special characters were NOT permitted in folder/file names on operating systems, still good practice though, cause I've seen even today popular modern day apps having trouble with special characters, etc.
