There can be one of the two cause for this error    Path is not correct -  but it is less likely as CreateDirectory should create any path unless path itself is not valid  read invalid characters Account through which your application is running don t have rights to create directory at path location  like if you are trying to create directory on shared drive with not enough privileges etc

I resolved a similar issue by simply restarting Visual Studio with admin rights    The problem was because it couldn t open one project related to Sharepoint without elevated access

File Copy file name  destination dir   file name Substring source dir Length   true     This line has the error because what the code expected is the directory name    file name  not the file name   This is the correct one  File Copy source dir   file name  destination dir   file name Substring source dir Length   true

Probably unrelated  but consider using Path Combine instead of destination dir   dir Substring       From the look of it  your  Substring   will leave a backlash at the beginning  but the helper classes like Path are there for a reason

The error is self explanatory  The path you are trying to access is not present   string source dir    E   Debug  VipBat   0      I m sure that this is not the correct path  Debug folder directly in E  drive looks wrong to me  I guess there must be the project name folder directory present    Second thing  what is  0  in your string  I am sure that it is an argument placeholder because folder name cannot contains  0  such name  So you need to use String Format   to replace the actual value   string source dir   String Format  E   Debug  VipBat   0   variableName     But first check the path existence that you are trying to access

Is the drive E a mapped drive  Then  it can be created by another account other than the user account  This may be the cause of the error

I had the same error  although in my case the problem was with the formatting of the DESTINATION path  The comments above are correct with respect to debugging the path string formatting  but there seems to be a bug in the File Copy exception reporting where it still throws back the SOURCE path instead of the DESTINATION path  So don t forget to look here as well   -TC
