File system access restriction

For security reasons, Qlik Sense in standard mode does not support paths in the data load script or functions and variables that expose the file system.

However, since file system paths were supported in QlikView, it is possible to disable standard mode and use legacy mode in order to reuse QlikView load scripts.

Disabling standard mode can create a security risk by exposing the file system.

Disabling standard mode

Security aspects when connecting to file based ODBC and OLE DB data connections

ODBC and OLE DB data connections using file-based drivers will expose the path to the connected data file in the connection string. The path can be exposed when the connection is edited, in the data selection dialog, or in certain SQL queries. This is the case both in standard mode and legacy mode.

If exposing the path to the data file is a concern, it is recommended to connect to the data file using a folder data connection if it is possible.

Limitations in standard mode

Several statements, variables and functions cannot be used or have limitations in standard mode. Using unsupported statements in the data load script produces an error when the load script runs. Error messages can be found in the script log file. Using unsupported variables and functions does not produce error messages or log file entries. Instead, the function returns NULL.

There is no indication that a variable, statement or function is unsupported when you are editing the data load script.

System variables

System variables
Variable	Standard mode	Legacy mode	Definition
Floppy	Not supported	Supported	Returns the drive letter of the first floppy drive found, normally a:.
CD	Not supported	Supported	Returns the drive letter of the first CD-ROM drive found. If no CD-ROM is found, then c: is returned.
QvPath	Not supported	Supported	Returns the browse string to the Qlik Sense executable.
QvRoot	Not supported	Supported	Returns the root directory of the Qlik Sense executable.
QvWorkPath	Not supported	Supported	Returns the browse string to the current Qlik Sense app.
QvWorkRoot	Not supported	Supported	Returns the root directory of the current Qlik Sense app.
WinPath	Not supported	Supported	Returns the browse string to Windows.
WinRoot	Not supported	Supported	Returns the root directory of Windows.
$(include=...)	Supported input: Path using library connection	Supported input: Path using library connection or file system	The Include/Must_Include variable specifies a file that contains text that should be included in the script and evaluated as script code. It is not used to add data. You can store parts of your script code in a separate text file and reuse it in several apps. This is a user-defined variable.

Regular script statements

Regular script statements
Statement	Standard mode	Legacy mode	Definition
Binary Binary	Supported input: Path using library connection	Supported input: Path using library connection or file system	The binary statement is used for loading data from another app.
Connect Connect	Supported input: Path using library connection	Supported input: Path using library connection or file system	The CONNECT statement is used to define Qlik Sense access to a general database through the OLE DB/ODBC interface. For ODBC, the data source first needs to be specified using the ODBC administrator.
Directory Directory	Supported input: Path using library connection	Supported input: Path using library connection or file system	The Directory statement defines which directory to look in for data files in subsequent LOAD statements, until a new Directory statement is made.
Execute Execute	Not supported	Supported input: Path using library connection or file system	The Execute statement is used to run other programs while Qlik Sense is loading data. For example, to make conversions that are necessary.
LOAD from ... Load	Supported input: Path using library connection	Supported input: Path using library connection or file system	The LOAD statement loads fields from a file, from data defined in the script, from a previously loaded table, from a web page, from the result of a subsequent SELECT statement or by generating data automatically.
Store into ... Store	Supported input: Path using library connection	Supported input: Path using library connection or file system	The Store statement creates a QVD, or text file.

Script control statements

Script control statements
Statement	Standard mode	Legacy mode	Definition
For each... filelist mask/dirlist mask For each..next	Supported input: Path using library connection Returned output: Library connection	Supported input: Path using library connection or file system Returned output: Library connection or file system path, depending on input	The filelist mask syntax produces a comma separated list of all files in the current directory matching the filelist mask. The dirlist mask syntax produces a comma separated list of all directories in the current directory matching the directory name mask.

File functions

File functions
Function	Standard mode	Legacy mode	Definition
Attribute() Attribute - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	Returns the value of the meta tags of different media files as text.
ConnectString() ConnectString - script function	Returned output: Library connection name	Library connection name or actual connection, depending on input	Returns the active connect string for ODBC or OLE DB connections.
FileDir() FileDir - script function	Returned output: Library connection	Returned output: Library connection or file system path, depending on input	The FileDir function returns a string containing the path to the directory of the table file currently being read.
FilePath() FilePath - script function	Returned output: Library connection	Returned output: Library connection or file system path, depending on input	The FilePath function returns a string containing the full path to the table file currently being read.
FileSize() FileSize - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	The FileSize function returns an integer containing the size in bytes of the file filename or, if no filename is specified, of the table file currently being read.
FileTime() FileTime - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	The FileTime function returns a timestamp in UTC format of the last modification of a specified file. If a file is not specified, the function returns a timestamp in UTC of the last modification of the currently read table file.
GetFolderPath() GetFolderPath - script function	Not supported	Returned output: Absolute path	The GetFolderPath function returns the value of the Microsoft Windows SHGetFolderPath function. This function takes as input the name of a Microsoft Windows folder and returns the full path of the folder.
QvdCreateTime() QvdCreateTime - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	This script function returns the XML-header timestamp from a QVD file, if any is present, otherwise it returns NULL. In the timestamp, time is provided in UTC.
QvdFieldName() QvdFieldName - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	This script function returns the name of field number fieldno in a QVD file. If the field does not exist NULL is returned.
QvdNoOfFields() QvdNoOfFields - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	This script function returns the number of fields in a QVD file.
QvdNoOfRecords() QvdNoOfRecords - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	This script function returns the number of records currently in a QVD file.
QvdTableName() QvdTableName - script function	Supported input: Path using library connection	Supported input: Path using library connection or file system	This script function returns the name of the table stored in a QVD file.

System functions

System functions
Function	Standard mode	Legacy mode	Definition
DocumentPath()	Not supported	Returned output: Absolute path	This function returns a string containing the full path to the current Qlik Sense app.
