Path, File and Folder Name Restrictions

You should only use the following ASCII characters for path, file and folder names:

• A through Z
• a through z
• 0 through 9
• underscore: _
• dash: -
• period: .

Windows Operation System

Windows operating systems have a maximum path length of 260 characters. An explanation from Microsoft is found here:

https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx

Although Windows will attempt to stop you from creating path lengths that are too long, it is possible to do this (from certain applications, cutting-and-pasting, etc.) If a project source file uses such a path, the project will not build correctly.

Additionally, there is a command-line limitation for Windows OS of 8191 characters. For details, see:

Section “Command line too long (Windows OS)”

Cross-Platform Operating Systems

If you plan on using MPLAB X IDE on different platforms (Windows, Mac, or Linux operating systems), be aware of these issues:

• Use the forward slash “/” in relative paths. The backslash “\” works only on Windows OS platforms. Example: #include headers/myheader.h.
• Linux OS is case-sensitive, so generictypedefs.h is not the same as GenericTypeDefs.h.
