  - fromFile
```
public static Optional<TSDataScanDir.MetaData> fromFile(Path filename)
```
  - getFileName
```
public Path getFileName()
```
    The name of the file.
  - getBegin
```
public org.joda.time.DateTime getBegin()
```
    The lowest timestamp in the file.
  - getEnd
```
public org.joda.time.DateTime getEnd()
```
    The highest timestamp in the file.

```
public short getVersionMajor()
```
    The major version of the file data.
  - getVersionMinor
```
public short getVersionMinor()
```
    The minor version of the file data.
  - getFileSize
```
public long getFileSize()
```
    The size of the file.
  - canAddSingleRecord
```
public boolean canAddSingleRecord()
```
    If the file supports adding records one at a time.
  - isUpgradable
```
public boolean isUpgradable()
```
    Check if the file is upgradable to the latest version of the file data used by the implementation. If a file is upgradable, it means that the data inside it is valid in both the version it currently has and the version the implementation uses. In that case, the WriteableTSDataFile implementation may opt to add new records to that file. Otherwise, it will have to start a new file to write records to.
    
    Returns:
    
    True if the file version can be set to the latest version, false otherwise.
