File System Limits

When you create a file or a folder, do you check that the full path is not too long?! Make sure that you handle the PathTooLongException:

 

PathTooLongException

 

Try to exceed the maximim lenght on Windows, and you’ll get this error:

 

Destination Path Too Long

 

Here are some limits in Windows APIs that you should know about:

 

#define MAX_PATH 260 // Maximum length of full path
#define MAX_DIR 256 // Maximum length of path component
#define MAX_FNAME 256 // Maximum length of file name component
#define MAX_EXT 256 // Maximum length of extension component
