Vba excel if exists file

The function that allows us to check if a file or folder exists is know as the DIR function.  The syntax for the DIR function is as follows:

DIR [( path [, attributes ])]

The PATH argument is basically an address which returns the name of your file or folder.  If the name is not found, DIR returns an empty string.

The ATTRIBUTES argument (which are optional) are listed in the below table.

ConstantVALUE	Value	Description
vbNormal	0	(Default) Files with no attributes
vbReadOnly	1	Read-only files
vbHidden	2	Hidden files
vbSystem	4	System files
vbDirectory	16	Directories or folders

The default is vbNormal, which are files with no specific attributes.  You can filter for files with a specific attribute by using the constants listed above.

An interesting thing you can use with the DIR function are wildcards.  Wildcards represent “any characters” and are useful when you want to capture multiple items in a search based on a pattern of characters.  There are two wildcard characters:

Asterisk (*) – This wildcard character will allow for any character(s) in any quantity.

Examples:  

Exc* (any text starting with “Exc”)

*el (any text ending with “el”)

Exc*el (any text starting with “Exc”, ending with “el”, and any character in between)

Question Mark (?) – This wildcards character will allow for any character in a single character position

Examples:   

??cel (The first and second characters can be anything, but the third through fifth characters must be “cel”)

Ex?el (The first and second characters must be “Ex”, the fourth and fifth characters must be “el”, but the third character can be anything)

Practical Examples

Task #1

We will use the DIR function to check if a file exists.  If the file doesn’t exist, we will display a “File does not exist” message to the user.  If the file exists, we will open the file.

Task #2

We will use the DIR function to check if a folder exists.  If the folder doesn’t exist, we will prompt the user to ask if they would like to create that folder.  If the responds with a “Yes”, we will create the folder for them.

Task #1 (Version 1) – Checking for the existence of a file

First, open the Visual Basic Editor (ALT-F11) and create an empty module (i.e. “LessonsFilesFolders”).

The DIR function returns a string, so we need to declare a variable named FileName to hold the returned value.

Dim FileName As String

The next step is to query a folder for a file and return the filename if it exists, or an empty string if the file does not exist.  We will store the response in the FileName variable we created in the previous step.

FileName = VBA.FileSystem.Dir(“your folder nameyour file name”)

In our example we will use the following code:

FileName = VBA.FileSystem.Dir(“C:UsersLGDesktopVBAS2_recordMacros_start.xlsx”)

If the file does not exist, the DIR function will return an empty string.  We will test for the empty string response with an IF statement.  If the file does not exist, we will display a message stating such.  If the file does exist, this first version will simply show the filename in a message box.

If FileName = VBA.Constants.vbNullString Then
    MsgBox "File does not exist."
Else
    MsgBox FileName
End If

The completed code should look like the following:

Sub FileExists()
Dim FileName As String
    FileName = VBA.FileSystem.Dir("C:UsersLGDesktopVBAS2_recordMacros_start.xlsx")
    If FileName = VBA.Constants.vbNullString Then
        MsgBox "File does not exist."
    Else
        MsgBox FileName
    End If
    
End Sub

Execute the code by pressing F5 and observe the response.

This confirms that the file exists in the defined folder.

Task #1 (Version 2) – Checking for the existence of a file using wildcards

Alter the code to use wildcards when searching for the filename.

FileName = VBA.FileSystem.Dir("C:UsersLGDesktopVBAS2_*start.xls?)

We will also alter the code; instead of displaying a message, we will open the requested file.

Workbooks.Open "C:UsersLGDesktopVBA" & FileName

The updated code should appear as follows:

Sub FileExists()
Dim FileName As String
    FileName = VBA.FileSystem.Dir("C:UsersLGDesktopVBAS2_*start.xls?")
    If FileName = VBA.Constants.vbNullString Then
        MsgBox "File does not exist."
    Else
        Workbooks.Open "C:UsersLGDesktopVBA" & FileName
    End If
    
End Sub

Execute the code by pressing F5 and observe that the file opens.

Task #2 – Check if a folder exists

In this task, we will check to see if a folder exists.  If the folder does not exist, we will prompt the user and ask if they would like to create the folder.

We will create two variables:

Path – Hold the full folderfilename information

Folder – Hold only the folder name

Dim Path as String
Dim Folder as String

We will set the Path variable to point to a folder that does not exist:

Path = “C:UsersLGDesktopVBAS12”

We will set the Folder variable to hold the folder location stored by the Path variable.  Because this is a folder, we will use the optional constant vbDirectory in the DIR function.

Folder = Dir(Path,vbDirectory)

As we did earlier, we will check to see if the response returns an empty string.  If the Folder variable contains an empty string, we will prompt the user to ask if they wish to create the folder.

We need to store the user’s response, so we will create a variable to hold the response.

Dim Answer as VbMsgBoxResult

If the folder does not exist, we will display a message and store the user’s response in the Answer variable.

Answer = MsgBox("Path does not exist. Would you like to create it?", vbYesNo, "Create Path?")

Now we will test the answer.  We will use a Case statement to test the response.

If the user responds with “Yes”, we will create the folder.  If the user responds with anything else, we will exit the subroutine.

Select Case Answer
    Case vbYes
        VBA.FileSystem.MkDir (Path)
    Case Else
        Exit Sub
End Select

If the folder does exist, we will inform the user of its existence with a message box response.

Else
    MsgBox "Folder exists."

The completed code should look like the following:

Sub Path_Exists()
Dim Path As String
Dim Folder As String
Dim Answer As VbMsgBoxResult
    Path = "C:UsersLGDesktopVBAS12"
    Folder = Dir(Path, vbDirectory)
 
    If Folder = vbNullString Then
        Answer = MsgBox("Path does not exist. Would you like to create it?", vbYesNo, "Create Path?")
        Select Case Answer
            Case vbYes
                VBA.FileSystem.MkDir (Path)
            Case Else
                Exit Sub
        End Select
    Else
        MsgBox "Folder exists."
    End If
End Sub

Execute the code by pressing F5.  Because the folder does not exist, we are presented with the following message prompt.

If we answer “Yes”, the folder is created.

If we execute the macro a second time, we see the following response.

This is because the folder was created in the previous test.

Conclusion

We have demonstrated how you can use the DIR function to test whether a file or folder exists and decide what actions you wish to perform depending on the outcome of the test.

VBA check if file exists example Excel Macro code helps to Check if file Exists in Location using Excel VBA. You can use FileSystemObject or Dir function to check if file Exists in Location using Excel VBA.

For example, When we are automating any task we generally save the output file in a location. Using this program we can check if there is any file exists already in the same location. So that we can delete or rename the old file.

Solution(s):

You can use FileSystemObject or Dir function to check if file Exists in Location using Excel VBA.Follwoing are the examples to show you how to check If a file is already exists in a folder or not. Follwoing are the two different methods.

Check if file Exists in Location using Excel VBA – Example Cases:

• Check if file Exists in Location using Excel VBA – Using FileSystemObjects
• Check if file Exists in Location using Excel VBA – Using Dir Function

Check if file Exists in Location using Excel VBA – Using FileSystemObjects

Following is the example to check if a file exists in a folder with using FileExists function of FileSystemObject.

Code:

'In this Example I am checking if Sample.xls file which exists in the same location of the macro file
Sub sbCheckingIfFileExists()

Dim FSO
Dim sFile As String

sFile = ThisWorkbook.Path & "Sample.xls"
'OR
'"C:Sample.xls" 'You can change this Loaction

Set FSO = CreateObject("Scripting.FileSystemObject")

If Not FSO.FileExists(sFile) Then
    MsgBox "Specified File Not Found", vbInformation, "Not Found"
Else
    MsgBox "Specified File Exists", vbInformation, "Exists"
End If

End Sub

Check if file Exists in Location using Excel VBA – Using Dir Function

Following is the example to check if a file exists in a folder with using Dir function.

Code:

'In this Example I am checking if Sample.xls file which exists in the same location of the macro file
Sub Check_If_File_Exists()

    Dim stFileName As String

    stFileName = ThisWorkbook.Path & "Sample.xls"  'You can change this location

    If Dir(stFileName) <> "" Then
        MsgBox "Specified File Exists", vbInformation, "Exists"
    Else
         MsgBox "Specified File Not Found", vbInformation, "Not Found"
    End If

End Sub

Output:

If file exists in a location, it will show following message. Otherwise it will show “Specified File Not Found” message.

Instructions:

1. Open an excel workbook
2. Press Alt+F11 to open VBA Editor
3. Insert a new module from Insert menu
4. Copy the above code and Paste in the code window
5. Press F5 to check the output
6. You should see a message box as shown above

   Hello,

   I like the above VBA coding and want to know if an macro can be created to see the list of files exist in some particular folder or not?
   and instead of msg box pop-up, it will just show it in one cell adjacent to the file name if it exist or not? If it can be done then it will resolve all my purpose. Please e-mail me at —- if you already have any sample macro for it.

   Thank you

   Thank you for the quick response!
   However, the link showed a Analysis of data and I need an macro to check for various files exist in particular folder or not. I am not sure if the same link can be modify for my need or not?

   Could you please help me and assist me if an macro can be created to check multiple files exist in the folder or not and instead of pop-up message box, it will show in excel columns only?

   Thanks Buddy,

   Analysis Tab is awesome, however it is not resolving my purpose completely. The tab is pulling the file names from the folder but I still need to check the names manually to find if anything missing.
   We save some same set of files each day in particular folder, so what I am asking is if through formula it is possible to check if file exist or not and will revert with “Yes” or “No” then it will be great.

   i am not very good at excel so it is difficult for me to frame the formula. Can you please assist me if possible?
