I am trying to copy a file using the following code:
File targetFile = new File(targetPath + File.separator + filename);
...
targetFile.createNewFile();
fileInputStream = new FileInputStream(fileToCopy);
fileOutputStream = new FileOutputStream(targetFile);
byte[] buffer = new byte[64*1024];
int i = 0;
while((i = fileInputStream.read(buffer)) != -1) {
fileOutputStream.write(buffer, 0, i);
}
For some users the targetFile.createNewFile
results in this exception:
java.io.IOException: The filename, directory name, or volume label syntax is incorrect
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(File.java:850)
Filename and directory name seem to be correct. The directory targetPath
is even checked for existence before the copy code is executed and the filename looks like this: AB_timestamp.xml
The user has write permissions to the targetPath
and can copy the file without problems using the OS.
As I don't have access to a machine this happens on yet and can't reproduce the problem on my own machine I turn to you for hints on the reason for this exception.
This can occur when filename has timestamp with colons, eg. myfile_HH:mm:ss.csv
Removing colons fixed the issue.
Try this, as it takes more care of adjusting directory separator characters in the path between targetPath and filename:
File targetFile = new File(targetPath, filename);
