Can I append data to the file ?

可以，可以使用RestorableTsFileIOWriter 实现追加写；
Yes, you can use RestorableTsFileIOWriter to append data to an existed TsFile.

Can I modify data in a TsFile?

不行， TsFile不能做数据修改，这种情况下要么使用IoTDB，要么自己组织多个TsFile并用后者替代前者的数据。
No, you can not modify data in a TsFile. If you need to modify data, use IoTDB interface, or you can manage several TsFiles and use the latter version to cover the previous versions.
