In today's digital age, the security of file passwords has become increasingly important. Whether it is important documents at work or private photos in life, we all hope to be able to protect their privacy. However, sometimes we may forget passwords or passwords may be stolen. What should we do at this time? Don't worry. Today I will share with you some practical skills and experience in recovering passwords for Excel, Word, PDF, PPT, RAR, ZIP, 7z and other files, so that you don't have to worry about passwords anymore!
I. Excel File Password Recovery
Excel is one of the commonly used office software in our daily work, and a lot of important data are saved in Excel files. If you forget the password of an Excel file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String Dim i As Integer Dim j As Integer Dim k As Integer Dim l As Integer
FileName = "C:\example.xlsx" 'The path of the Excel file that needs to recover the password
Password = ""
For i = 65 To 90 'Capital letters A-Z
For j = 65 To 90
For k = 65 To 90
For l = 65 To 90
Password = Chr(i) & Chr(j) & Chr(k) & Chr(l)
On Error Resume Next
Workbooks.Open Filename:=FileName, Password:=Password
If Err.Number = 0 Then
MsgBox "The password is: " & Password
Exit Sub
End If
Err.Clear
Next l
Next k
Next j
Next i
End Sub ```
This code will try all password combinations from AAAA to ZZZZ to open the specified Excel file. If the password is correct, a message box will pop up to display the password; if the password is incorrect, it will continue to try the next password combination. It should be noted that this method requires a certain programming foundation. If you are not familiar with VBA programming, it is recommended not to try. 3. Contacting the file owner: If you forget the password of an Excel file yourself, the best way is to contact the file owner and ask them for the password. If it is a work file, you can ask your colleagues or superiors; if it is a private file, you can ask the creator of the file.
II. Word File Password Recovery
Word is also one of the commonly used office software. Many documents are saved in Word files. If you forget the password of a Word file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String Dim i As Integer Dim j As Integer Dim k As Integer Dim l As Integer
FileName = "C:\example.docx" 'The path of the Word file that needs to recover the password
Password = ""
For i = 65 To 90 'Capital letters A-Z
For j = 65 To 90
For k = 65 To 90
For l = 65 To 90
Password = Chr(i) & Chr(j) & Chr(k) & Chr(l)
On Error Resume Next
Documents.Open FileName:=FileName, Password:=Password
If Err.Number = 0 Then
MsgBox "The password is: " & Password
Exit Sub
End If
Err.Clear
Next l
Next k
Next j
Next i
End Sub ```
The principle of this code is similar to the VBA code for Excel file password recovery. It also tries all possible password combinations to open the Word file. 3. Contacting the file owner: Similar to Excel files, the best way is to contact the file owner and ask them for the password.
III. PDF File Password Recovery
PDF files are a commonly used document format, and many important files are saved in PDF format. If you forget the password of a PDF file, we can recover it through the following methods:
IV. PPT File Password Recovery
PPT is a software commonly used when making presentation slides. Many important presentation slides are saved in PPT files. If you forget the password of a PPT file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String Dim i As Integer Dim j As Integer Dim k As Integer Dim l As Integer
FileName = "C:\example.ppt" 'The path of the PPT file that needs to recover the password
Password = ""
For i = 65 To 90 'Capital letters A-Z
For j = 65 To 90
For k = 65 To 90
For l = 65 To 90
Password = Chr(i) & Chr(j) & Chr(k) & Chr(l)
On Error Resume Next
Presentations.Open FileName:=FileName, Password:=Password
If Err.Number = 0 Then
MsgBox "The password is: " & Password
Exit Sub
End If
Err.Clear
Next l
Next k
Next j
Next i
End Sub ```
The principle of this code is similar to the VBA code for Excel, Word, and PDF file password recovery. It also tries all possible password combinations to open the PPT file. 3. Contacting the file owner: Similar to other files, the best way is to contact the file owner and ask them for the password.
V. RAR, ZIP, 7z File Password Recovery
RAR, ZIP, and 7z are commonly used compressed file formats, and many important files are saved in compressed file form. If you forget the password of a RAR, ZIP, or 7z file, we can recover it through the following methods:
