Difference between PathAppend and PathCombine in Win32 API

Question

I want to understand what's the difference between those functions, and which of them should I use for work with paths?

For example: I want "C:\Temp" + "..\Folder" = "C:\Folder"

Thanks

Answer 1

PathCanonicalize() might be worth mentioning, in case the strings are already concatenated.

Answer 2

You have to use PathCombine for this.

Concatenates two strings that represent properly formed paths into one path; also concatenates any relative path elements.

PathAppend specifically rules out relative path qualifiers, per the MSN docs:

The path supplied in pszPath cannot begin with "..\" or ".\" to produce a relative path string.
