  Type Name Description
Public function Virtual bool

CopyFile ( const TCHAR* To,
const TCHAR* From,
EPlatformFileRead ReadFlags,
EPlatformFileWrite WriteFlags
)

 Copy a file. This will fail if the destination file already exists.
Public function Virtual bool

CreateDirectory ( const TCHAR* Directory
)

 Create a directory and return true if the directory was created or already existed.
Public function Virtual bool

DeleteDirectory ( const TCHAR* Directory
)

 Delete a directory and return true if the directory was deleted or otherwise does not exist.
Public function Virtual bool

DeleteFile ( const TCHAR* Filename
)

 Delete a file and return true if the file exists. Will not delete read only files.
Public function Virtual bool
DirectoryExists

( const TCHAR* Directory
)

 Return true if the directory exists.
Public function Virtual bool

FileExists ( const TCHAR* Filename
)

 Return true if the file exists.
Public function Virtual int64

FileSize ( const TCHAR* Filename
)

 Return the size of the file, or -1 if it doesn't exist.
Public function Virtual FDateTime

GetAccessTimeStamp ( const TCHAR* Filename
)

 Return the last access time of a file.
Public function Virtual FString

GetFilenameOnDisk ( const TCHAR* Filename
)

 For case insensitive filesystems, returns the full path of the file with the same case as in the filesystem
Public function Virtual FFileStatData

GetStatData ( const TCHAR* FilenameOrDirectory
)

 Return the stat data for the given file or directory.
Public function Virtual FDateTime

GetTimeStamp ( const TCHAR* Filename
)

 Return the modification time of a file.
Public function Virtual bool

IsReadOnly ( const TCHAR* Filename
)

 Return true if the file is read only.
Public function Virtual ESymlinkResult

IsSymlink ( const TCHAR* Filename
)

 Return true if the file is a symbolic link
Public function Virtual bool

IterateDirectory ( const TCHAR* Directory,
FDirectoryVisitor& Visitor
)

 Call the Visit function of the visitor once for each file or directory in a single directory.
Public function Virtual bool

IterateDirectoryStat ( const TCHAR* Directory,
FDirectoryStatVisitor& Visitor
)

 Call the Visit function of the visitor once for each file or directory in a single directory.
Public function Virtual bool

MoveFile ( const TCHAR* To,
const TCHAR* From
)

 Attempt to move a file. Return true if successful. Will not overwrite existing files.
Public function Virtual IMappedFileHandle *

OpenMapped ( const TCHAR* Filename
)

 Open a file for async reading. This call does hit the disk; it is synchronous open.
Public function Virtual IFileHandle *

OpenRead ( const TCHAR* Filename,
bool bAllowWrite
)

 Attempt to open a file for reading.
Public function Virtual IFileHandle *

OpenWrite ( const TCHAR* Filename,
bool bAppend,
bool bAllowRead
)

 Attempt to open a file for writing.
Public function Virtual bool

SetReadOnly ( const TCHAR* Filename,
bool bNewReadOnlyValue
)
