i try to rename a file using vb.net in this way:
my.computer.filesyste.rename(oldname,newname)
But if i use a software to recover files deleted, i find a file named :"_ldname", and if i recovery the file "_ldname" i have, in this way, two files equals.
Can i do this without have a duplicate of my file?
Best regards
Sebastiano
You cannot, this is a windows filesystem limitation and nothing to do with programming. Two files cannot have the same name in the same location.
The recovery software should be forcing a rename to Myfile(1).txt or something like that to distinguish between the two files.
You could always use:
If File.Exists(path) = False Then
To make sure the file doesn't already exists. Then if it does exist you could add a "(1)" to the file name.

I use DotNetZip for creating zips. It has many option but I couldn't find if it is possible to store the disk where the file is located, in the archive. E.g. like the Absolute mode in 7-Zip. As far as I can see I can only do this:
zip.AddFile(cFileFull, cPath);
When cFileFull is e.g. "c:\temp\SomeFile.txt" and cPath = "c:\temp" opening the zipfile shows
temp
while I would like to see
C
and then, when I click on C
temp
This allows storing the same path/file found on different drives. Is this possible?
I'm relatively new to Netlogo and already struggling ;)
I have the following problem: I want my program to open a folder, check a file in that folder and afterwards remove that file from that folder. I figured the best way to do this is via a while loop, but I'm struggling to find the right syntax. Hope you all can help!
The command 'file-open' will open a file using the path provided (the string after file-open: e.g. file-open "C:\Documents\model-out.txt" will open a file titled model-out.txt in the Documents folder on the C drive.)
You can then use 'file-read' or 'file-write' to read or write to the file respectively.
The command 'file-close' will close the file, which then can be deleted with 'file-delete'.
You can also check if a file exists in a folder using the command if file-exists? "C:\Documents\model-out.txt", and if true, the file can be deleted using file-delete.
Also check the command 'set-current-directory'.
Best,
I've been trying to delete files having same extension by using labview.
I am using delete.vi to delete files like below.
But, I want to delete all files having same extension.
Imagine a folder like below.
Here, I would like to delete all files having '.MASTER, .jou, .IFPDAT, . f06, .f04, .DBALL' as extension.
I would like to make an automatic file delete function like below.
Would there be any good examples?
The best way is to use "List Folder" with wild-cards (using "pattern" input) to get an array of files. Then you have to delete files one by one.
You can use System Exec.vi.
Here's an example to delete all DXF files in a folder:

[Question] Does Session::RemoveFiles() remove files in sub directory of source directory? If not, how to implement this ability?
(Please do not ask me why I have the remote directory as /C/testTransfer/. The code just for testing purpose.)
I have a SFTP program using WinSCP .Net assembly. Program language is C++/CLI. It opens up a work file. The file contains many lines of FTP instructions.
One type of instruction I have to handle is to transfer *.txt from source directory. The source directory may contain sub directories which may contain .txt as well. Once transfer is successful, delete the source files.
I use Session::GetFiles() for the transfer. It correctly transfer all .txt files (/C/testTransfer/*.txt), even those in sub directories (/C/testTransfer/sub/*.txt), in the source to the destination.
transferOptions->FileMask = "*.txt";
session->GetFiles("/C/testTransfer", "C:\\temp\\win", false, transferOption);
Now to remove, I use session->RemoveFiles("/C/testTransfer/*.txt"). I only see *.txt in the source (/C/testTransfer/*.txt), but not in the sub directory (/C/testTransfer/sub/*.txt), are removed.
The Session::RemoveFiles can remove even files in subdirectories in general. But not this way with wildcard, because WinSCP will not descend to subdirectories that do not match the wildcard (*.txt). Also note that even if you do not need the wildcard, the Session::RemoveFiles would remove even the subdirectories themselves, what I'm not sure you want it to.
Though you have other (and better = more safe) options:
Use the remove parameter of the Session::GetFiles method to instruct it to remove source file after successful transfer.
If you need to delete source files transactionally (=only after download of all files succeed), iterate the TransferOperationResult::Transfers returned by Session::GetFiles and call the Session::RemoveFiles for each (unless the TransferEventArgs::Error is not null).
Use the TransferEventArgs::FileName to get a file path to pass to the Session::RemoveFiles. Use the RemotePath::EscapeFileMask to escape the file name before passing it to the Session::RemoveFiles.
There's a similar full example available for Moving local files to different location after successful upload.
To recursively delete files matching a wildcard in a standalone operation (not after downloading the same files), use the Session::EnumerateRemoteFiles. Pass your wildcard to its mask argument. Use the EnumerationOptions.AllDirectories option for recursion.
Call the Session::RemoveFiles for each returned file. Use the RemotePath::EscapeFileMask to escape the file name before passing it to the Session::RemoveFiles.
By default AutoCAD installs a text based file called acad2010.lsp at the set location below
Dim FILE_NAME As String = "C:\Program Files\AutoCAD 2010\Support\acad2010.lsp"
However it my be that the user/ administrator/ or third party has changed the location of this file. Is it possible to then locate it using the following
Dim FILE_NAME As String = "C:\*\acad2010.lsp"
In other words search the entire c:\ drive for file acad2010.lsp?
If this doesn't work can you please let me know what would?
You could search for it with an FSO. It's not going to be fast however you do it but this is the fastest way I can think of.
http://www.microbion.co.uk/developers/fso.htm should give you a rough idea of how it's done.
Your solution will not work. Is not possible to locate it using *. (BTW is possible in ms-builds scripts). The only way of doing it is:
1- Create a FindFile function (check for example
http://xlvba.3.forumer.com/index.php?showtopic=125)
2- Use it to locate the exact path of the file. (It could be really time
consuming)
3- From this point your code is the same...
Unfortunately, you can't use wildcards in a filepath. You have two options:
Prompt the user for the file location using the "Open File" dialog. The code to do this varies based on which Office product you are using. In Excel, you would use the Application.FindFile method (more info here).
Write your own function to search the filesystem for the file. Microsoft provides an example here.
If that file is used by internal functions of the application, the installer will have recorded a registry key for the file's location.
Open regedit.exe and search for the file name and path.
You can read a registry entry using this VBA one-liner:
CreateObject("WScript.Shell").RegRead(strRegPath)
You may need a terminating backslash on the key address, but that's a safe and simple registry access method. More details on the MSDN site:
