<Result> = fChangeExtension(<File path> , <New extension>)
<Result>: Boolean
  • True if the size changed,
  • False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
<File path>: Character string
File to be used (up to 260 characters). This parameter can correspond to:
  • a file name. This file will be automatically searched in the current directory (returned by fCurrentDir).
  • a file name with its full or relative path. A UNC path can be used.
<New extension>: Character string
New extension. If the new extension does not have a leading dot ".", it will be added automatically.
Remarks
If fChangeExtension handles a file with multiple extensions, only the last extension will change. For example, if you change the extension of "MyFile.log.doc", the result will be "MyFile.log.docx".
