             Summary: CopyFrom method doesn't update File Size after replacing file
                 Key: VFS-842
                 URL: https://issues.apache.org/jira/browse/VFS-842
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.9.0
            Reporter: Usman Ashraf Bajwah


Consider the scenario where we have two folders source and destination both have file with same name use copyFrom method file will be copied (replaced) in the destination folder alright but size of the file WILL NOT BE UPDATED IF THE SIZE OF DESTINATION FILE BEFORE COPY WAS GREATER THAN THE SIZE OF SOURCE FILE. In order to produce this issue. Use following code. and also take 2 image files in two different folders. Also make sure the destination folder contains image with higher size.

{color:#000000}I have verified the file is successfully copied but on File explorer the old size is showing. It seems there is some issue while we write the content of the file. Please let me know if you need any information{color}
