```
public void setFileLastModified(java.io.File file,
                                long time)
```
    Calls File.setLastModified(long time). Originally written to to dynamically bind to that call on Java1.2+.
    
    Parameters:
    
    file - the file whose modified time is to be set
    
    time - the time to which the last modified time is to be set. if this is -1, the current time is used.
  - resolveFile
```
public java.io.File resolveFile(java.io.File file,
                                java.lang.String filename)
```
    Interpret the filename as a file relative to the given file unless the filename already represents an absolute filename. Differs from new File(file, filename) in that the resulting File's path will always be a normalized, absolute pathname. Also, if it is determined that filename is context-relative, file will be discarded and the reference will be resolved using available context/state information about the filesystem.
    
    Parameters:
    
    file - the "reference" file for relative paths. This instance must be an absolute file and must not contain "./" or "../" sequences (same for \ instead of /). If it is null, this call is equivalent to new java.io.File(filename).getAbsoluteFile().
    
    filename - a file name.
    
    Returns:
    
    an absolute file.
    
    Throws:
    
    java.lang.NullPointerException - if filename is null.
  - isContextRelativePath
```
public static boolean isContextRelativePath(java.lang.String filename)
```
    On DOS and NetWare, the evaluation of certain file specifications is context-dependent. These are filenames beginning with a single separator (relative to current root directory) and filenames with a drive specification and no intervening separator (relative to current directory of the specified root).
    
    Parameters:
    
    filename - the filename to evaluate.
    
    Returns:
    
    true if the filename is relative to system context.
    
    Throws:
    
    java.lang.NullPointerException - if filename is null.
    
    Since:
    
    Ant 1.7
  - isAbsolutePath
```
public static boolean isAbsolutePath(java.lang.String filename)
```
    Verifies that the specified filename represents an absolute path. Differs from new java.io.File("filename").isAbsolute() in that a path beginning with a double file separator--signifying a Windows UNC--must at minimum match "\\a\b" to be considered an absolute path.
    
    Parameters:
    
    filename - the filename to be checked.
    
    Returns:
    
    true if the filename represents an absolute path.
    
    Throws:
    
    java.lang.NullPointerException - if filename is null.
    
    Since:
    
    Ant 1.6.3
  - translatePath
```
public static java.lang.String translatePath(java.lang.String toProcess)
```
    Translate a path into its native (platform specific) format.
    This method uses PathTokenizer to separate the input path into its components. This handles DOS style paths in a relatively sensible way. The file separators are then converted to their platform specific versions.
    
    Parameters:
    
    toProcess - The path to be translated. May be null.
    
    Returns:
    
    the native version of the specified path or an empty string if the path is null or empty.
    
    Since:
    
    ant 1.7
    
    See Also:
    
    PathTokenizer
  - normalize
```
public java.io.File normalize(java.lang.String path)
```
    "Normalize" the given absolute path.
    This includes:
    - Uppercase the drive letter if there is one.
    - Remove redundant slashes after the drive spec.
    - Resolve all ./, .\, ../ and ..\ sequences.
    - DOS style paths that start with a drive letter will have \ as the separator.
    Unlike File.getCanonicalPath() this method specifically does not resolve symbolic links.
    
    If the path tries to go beyond the file system root (i.e. it contains more ".." segments than can be travelled up) the method will return the original path unchanged.
    Parameters:
    
    path - the path to be normalized.
    
    Returns:
    
    the normalized version of the path.
    
    Throws:
    
    java.lang.NullPointerException - if path is null.
  - dissect
```
public java.lang.String[] dissect(java.lang.String path)
```
    Dissect the specified absolute path.
    
    Parameters:
    
    path - the path to dissect.
    
    Returns:
    
    String[] {root, remaining path}.
    
    Throws:
    
    java.lang.NullPointerException - if path is null.
    
    Since:
    
    Ant 1.7
  - toVMSPath
```
public java.lang.String toVMSPath(java.io.File f)
```
    Returns a VMS String representation of a File object. This is useful since the JVM by default internally converts VMS paths to Unix style. The returned String is always an absolute path.
    
    Parameters:
    
    f - The File to get the VMS path for.
    
    Returns:
    
    The absolute VMS path to f.

```
public boolean createNewFile(java.io.File f)
                      throws java.io.IOException
```
    This was originally an emulation of File.createNewFile for JDK 1.1, but it is now implemented using that method (Ant 1.6.3 onwards).
    This method has historically not guaranteed that the operation was atomic. In its current implementation it is.
    
    Parameters:
    
    f - the file to be created.
    
    Returns:
    
    true if the file did not exist already.
    
    Throws:
    
    java.io.IOException - on error.

```
    Create a new file, optionally creating parent directories.
    
    Parameters:
    
    f - the file to be created.
    
    mkdirs - boolean whether to create parent directories.

```
    Deprecated. use SymbolicLinkUtils instead
    
    Checks whether a given file is a symbolic link.
    It doesn't really test for symbolic links but whether the canonical and absolute paths of the file are identical--this may lead to false positives on some platforms.
    
    Parameters:
    
    parent - the parent directory of the file to test
    
    name - the name of the file to test.
    
    Returns:
    
    true if the file is a symbolic link.

```
    Removes a leading path from a second path.
    This method uses normalize(java.lang.String) under the covers and does not resolve symbolic links.
    
    Parameters:
    
    leading - The leading path, must not be null, must be absolute.
    
    path - The path to remove from, must not be null, must be absolute.
    
    Returns:
    
    path's normalized absolute if it doesn't start with leading; path's path with leading's path removed otherwise.
    
    Since:

public boolean isLeadingPath(java.io.File leading,
                             java.io.File path)
```
    Learn whether one path "leads" another.
    This method uses normalize(java.lang.String) under the covers and does not resolve symbolic links.
    
    If either path tries to go beyond the file system root (i.e. it contains more ".." segments than can be travelled up) the method will return false.
    
    Parameters:
    
    leading - The leading path, must not be null, must be absolute.
    
    path - The path to check, must not be null, must be absolute.

  - toURI
```
public java.lang.String toURI(java.lang.String path)
```
    Constructs a file: URI that represents the external form of the given pathname.
    Will be an absolute URI if the given path is absolute.
    
    This code encodes non ASCII characters too.
    
    The coding of the output is the same as what File.toURI().toASCIIString() produces
    See dt-sysid which makes some mention of how characters not supported by URI Reference syntax should be escaped.
    
    Parameters:
    
    path - the path in the local file system.
    
    Returns:
    
    the URI version of the local path.
    
    Since:

  - fromURI
```
public java.lang.String fromURI(java.lang.String uri)
```
    Constructs a file path from a file: URI.
    Will be an absolute path if the given URI is absolute.
    
    Swallows '%' that are not followed by two characters, doesn't deal with non-ASCII characters.
    
    Parameters:
    
    uri - the URI designating a file in the local filesystem.
    
    Returns:
    
    the local file system path for the file.

```
    Compares two filenames.
    Unlike java.io.File#equals this method will try to compare the absolute paths and "normalize" the filenames before comparing them.
    
    Parameters:
    
    f1 - the file whose name is to be compared.
    
    f2 - the other file whose name is to be compared.

                   java.io.File to)
            throws java.io.IOException
```
    Renames a file, even if that involves crossing file system boundaries.
    This will remove to (if it exists), ensure that to's parent directory exists and move from, which involves deleting from as well.
    
    Parameters:
    
    from - the file to move.
    
    to - the new file name.
    
    Throws:

  - getFileTimestampGranularity
```
public long getFileTimestampGranularity()
```
    Get the granularity of file timestamps. The choice is made based on OS, which is incorrect--it should really be by filesystem. We do not have an easy way to probe for file systems, however, so this heuristic gives us a decent default.
    
    Returns:
    
    the difference, in milliseconds, which two file timestamps must have in order for the two files to be considered to have different timestamps.
  - hasErrorInCase
```
public boolean hasErrorInCase(java.io.File localFile)
```
    test whether a file or directory exists, with an error in the upper/lower case spelling of the name. Using this method is only interesting on case insensitive file systems (Windows).
    It will return true only if 3 conditions are met:
    - operating system is case insensitive
    - file exists
    - actual name from directory reading is different from the supplied argument
    The purpose is to identify files or directories on case-insensitive filesystems whose case is not what is expected.
    Possibly to rename them afterwards to the desired upper/lowercase combination.
    Parameters:
    
    localFile - file to test
    
    Returns:
    
    true if the file exists and the case of the actual file is not the case of the parameter

```
    Returns true if the source is older than the dest. If the dest file does not exist, then the test returns false; it is implicitly not up do date.
    
    Parameters:
    
    source - source file (should be the older).
    
    dest - dest file (should be the newer).
