## Description

### Methods

| `function MoveToFirstFile: Boolean;`
Moves the cursor to the first file in the archive. Returns true (1) if the cursor position was set successfully.

| `function MoveToNextFile: Boolean;`
Moves the cursor to the next file in the archive. Returns true (1) if the cursor position was set successfully.

| `function MoveToFile(const fileName: ustring; caseSensitive: Boolean): Boolean;`

| `function Close: Boolean;`
Closes the archive. This should be called directly to ensure that cleanup occurs on the correct thread.

| `function GetFileName: ustring;`
Returns the name of the file.

| `function GetFileSize: Int64;`
Returns the uncompressed size of the file.

| `function GetFileLastModified: TCefBaseTime;`
Returns the last modified timestamp for the file.

| `function OpenFile(const password: ustring): Boolean;`
Opens the file for reading of uncompressed data. A read password may optionally be specified.

| `function CloseFile: Boolean;`
Closes the file.

| `function ReadFile(buffer: Pointer; bufferSize: NativeUInt): Integer;`
Read uncompressed file contents into the specified buffer. Returns < 0 if an error occurred, 0 if at the end of file, or the number of bytes read.

| `function Tell: Int64;`
Returns the current offset in the uncompressed file contents.

| `function Eof: Boolean;`
Returns true (1) if at end of the file contents.
