                                 boolean copyAndDeleteOnRenameFail)
                          throws IOException

Renames a file.

Parameters:

from - the from file

to - the to file

copyAndDeleteOnRenameFail - whether to fallback and do copy and delete, if renameTo fails

Returns:

true if the file was renamed, otherwise false

Throws:

IOException - is thrown if error renaming file

renameFileUsingCopy

public static boolean renameFileUsingCopy(File from,
                                          File to)
                                   throws IOException

Rename file using copy and delete strategy. This is primarily used in environments where the regular rename operation is unreliable.

Parameters:

from - the file to be renamed

to - the new target file

Returns:

true if the file was renamed successfully, otherwise false

Throws:

IOException - If an I/O error occurs during copy or delete operations.

copyFile

public static void copyFile(File from,
                            File to)
                     throws IOException

Copies the file

Parameters:

from - the source file

to - the destination file

Throws:

IOException - If an I/O error occurs during copy operation

deleteFile

public static boolean deleteFile(File file)

Deletes the file.

This implementation will attempt to delete the file up till three times with one second delay, which can mitigate problems on deleting files on some platforms such as Windows.

Parameters:

file - the file to delete

isAbsolute

public static boolean isAbsolute(File file)

Is the given file an absolute file.

Will also work around issue on Windows to consider files on Windows starting with a \ as absolute files. This makes the logic consistent across all OS platforms.

Parameters:

file - the file

Returns:

true if its an absolute path, false otherwise.

createNewFile

public static boolean createNewFile(File file)
                             throws IOException

Creates a new file.

Parameters:

file - the file

Returns:

true if created a new file, false otherwise

Throws:

IOException - is thrown if error creating the new file
