TLPD is designed to tackle the 'path name too long' issue. It scans the directory tree, searching for files and folders with full path name that may be too long for Windows to handle. TLPD is portable, has silent mode. ReadMe and source are available.
Excellent, useful tool, elegantly simple to use. Will search ALL directories on ALL drives by default, or the user may choose to navigate to an individual folder path; also offers the option to choose the number of characters ("maximum threshold") of the full path length user wishes to check for. All in all, this small-footprint utility is as handy as a shirt pocket..."Support" rcv'd only a "Just OK" (3) rating from this user, but truthfully, the product & it's use is so straightforward that none should be required
