The simplest thing is to make the file read only. Hiding it will only protect you from the mildly curious. I have my systems set to show hidden files...that is not at all uncommon.

Answer 3

how are you going to write to this file if you don't want it modified?



you can set the File Attributes to ReadOnly, but...

I guess you could check if the User is you, and if so set it to read/write. If not you set it to ReadOnly. Don't know if that would work, but worth a try

see this link for setting the Attributes

Answer 4

By Using VB.Net you can use following ways to secure your file to an extend. Either you can mark your file as ReadOnly, Hidden or as a System File.

Dim attribute As System.IO.FileAttributes = IO.FileAttributes.Encrypted
System.IO.File.SetAttributes("file1.txt", attribute)

Dim attribute As System.IO.FileAttributes = IO.FileAttributes.Hidden
System.IO.File.SetAttributes("file1.txt", attribute)

Dim attribute As System.IO.FileAttributes = IO.FileAttributes.System
System.IO.File.SetAttributes("file1.txt", attribute)

You should consider different method to protect file from tampering, Readonly and Hidden will not work because user can remove readonly attribute from file through properties. You can use resgistry or encrypt/encode the text before save to file. Also, you can put the text file in IsolatedStorage

If that what you want, take it. If not, ignored it and no complain
