I hope the maximum is as randor suggested.
But optimal condition may be according to your need.
if application dont bother about time but memory then split into small size and large number of file say 5-10k.
but if your application bother about time them split into 250-512k size files

Let me tell you the splitting of files will not be depended on the file size and the number of partitions.
I mean if you have 10Mb file if u need to divide it in to 10 files then each file will have 1024kb and 128 byte extra to identify the next file link.But as you have 128 byte*10 extra bytes to store your file size willbe more once you add the size of all files.

There is no maximum, except the value that you decide. As Randor said, if you have a 1MB source file you can split into 1048576 1-byte subfiles. Maybe if you explain why you want to do this then a better suggestion could be made.

Actually, the maximum would be the number of clusters on a given partition.

The likelihood of reaching this is quite small, which is why I ignored it. I was more interested in trying to discover what he was trying to do, but I guess we'll never know.

Cluster size is very small usually, if NTFS then it can have maximum default value of 4 KB. It will be not problem to keep file size greater than 4KB. In Actual scenario, no application can create a huge amount of file, so we can ignore it as Richard said. If such a design is done then it should have a strong reason else your design is having some big problem.

I think his question was academic and since you can split a file into an infinite number of zero byte files (theoretically), the limit would be the number of clusters of the given partition.

Yes it seems to be, 5* for this guess

I think his question was purely academic, his (her?) responses would indicate that.

I have written application on Visual C++ . It is mainly MFC Application.
I can code .net also(with respect to C++ )
At runtime if .net framework is installed on target machine my MFC application has act as MFC .net application otherwise it act as Simple MFC application.
Is it possible ? ( I don`t want to compile with .net because many of our customers not dependent on .net )
Expecting Suggestions

If you have to work on machines without .NET...
And you are prepared to program in MFC...
And MFC works on machine with .NET...
Then where's your problem?

Now My need is.
I want to create a application like the following

You need to handle the WM_SETFOCUS message and not call the base class handler to hide the carot.

I have a CTreeCtrl defined in my header with a instance of m_cTree. Here's a brief description of how the Tree looks:
[+] Reports (main Heading)
[+]Construction (child of Reports)
[+] Materials (child of Construction)
Materials Report.txt(the ".txt" is only to show you this is the actual report)
[+]Maintenance (child of Reports)
Maintenance Report.txt(the ".txt" is only to show you this is the actual report)
[+] Cost (child of Maintenance)
[+]Exspenses (child of Reports)
[+] Job Cost (child of Exspenses)
Exspenses Report.txt(the ".txt" is only to show you this is the actual report)
======================= end of example ======================
In OnNM_ClickTreeCtrl()
I cannot get the reports using this:
HTREEITEM hItem= m_cTree.GetSelectedItem();
HTREEITEM hChildItem = m_cTree.GetChildItem(hItem);
CString sSelText= m_cTree.GetItemText( hItem );
What is returns is whatever is selected including the button("[+]", the main heading, each child and finally the report. How do I only receive the click on the Reports themselves, not all the headings?
PLEASE use my example in your explaination, WITH(please) the appropriate code.
Thanks in advance.

Its better to handle this in the selection changed event(TVN_SELCHANGED) other wise, if some one operate the tree control through keyboard, your application wont work.
Larry Mills Sr wrote: How do I only receive the click on the Reports themselves, not all the headings?
You can use the item data corresponding to each item, to identify whether the items is report or not. I mean, while inserting the report, you should set the item data(SetItemData) as some value, say X. When the selection change occurs, retrive the item data correspoding to that item, check whether the item data is X.

Could you please provide a workable example for TVN_SELCHANGED?
Here's How I set up the TreeCtrl:
strItems[0]= _T("Reports");
strItems[1]= _T("Construction");
strItems[2]= _T("Materials");
HTREEITEM hReportsItemRoot= m_cTree.InsertItem(strItems[0]);
HTREEITEM hConstItemRoot= m_cTree.InsertItem(strItems[1], hReportsItemRoot);
HTREEITEM hMaterialsItemRoot= m_cTree.InsertItem(strItems[2],hConstItemRoot);
In your explaination, could you please use my example data, Please.

Hi
I have an application written in VB that checks whether a new wav file has been added to a folder by using the following:
MyFile = Dir("C:\MyDirectory\*.wav")
If MyFile contains a string, the file is then moved to another directory to manipulate.
I wish to do the same in VC (6.0) - have you any suggestions?
Thanks for any help that you can give!
Mike

Take a look at the FindFirstFile/FindNextFile[^] functions; they may be what you need.

Excellent - thanks very much - using the example got exactly what I wanted!
Thanks very much
