Next "available" File/Folder Name,...
in [Win32 Kernel]
|
From: Kerem Gümrükcü on 27 Jan 2010 04:00 Hi, i am looking for some API that will give me the next available file/folder name if the file/folder aleady exists. Example: you have a file named "New Text.txt", o the operating system suggests here "New Text(1).txt" if you create a new file within the shell. Is there any API that could give me the next available name for a file if i provide a filename as input? I guess its some shell interface or function, but i could not find anything so far,... Thanks in advance,...

I use the following for files: internal static string GetUniqueFilePath(string filePathIN) { int count = 1; string result = filePathIN; FileInfo fInfo = new FileInfo(result); if (fInfo.Exists) { do { result = filePathIN + "." + count.ToString("0000"); count++; fInfo = new FileInfo(result); } while (fInfo.Exists); } return result; } It adds the number at the end so you would need to tweak it a bit to put the number in a different place. -- Jeff Gaines Dorset UK There are 3 types of people in this world.

I dont want to reinvent the wheel if there is such a function already build into windows itself,...if not, i have to go the hard way,...

Once you had that "next available file/folder name" and just before you can create it, your program can be preempted and someone else can calculate this file/folder and create it, so what value will your prior call to this imaginary function have?. Having a function that does this as an API is subject to race conditions, so it is per se useless, unless tightly coupled with a file/foldeer creation call. The only sure thing is a function that tries to *create* the next possible file/folder. You mentioned PathMakeUniqueName, I never used that, does it only "suggest" the file name or does it create the file as well? If it doesn't create the file name, you will have to use that in a loop until a combination of the result of both PathMakeUniqueName and CreateFile succeed. BTW: MSDN online says that PathMakeUniqueName is suppported on W2K as well. -- S
