What are diskcache and voicefiles exactly for? can...

Hi,
just in the phone’s Memory card I have folder “cities” having 2 folders “diskcache” and “voicefiles”; they both are about 200 MB.
voicefiles include voice files e.g. “take the tenth exit”..“half a mile”
diskcahe includes several folders from a to z with unknown files inside.
What are these? I can’t find any use....
Are they safe to delete?

Solved!
Go to Solution.

As has already been stated by some of our members, these folders contain data for Ovi Maps. You can delete these without damaging the operation of your phone, but if you use Maps then you are recommended to manage the content using Ovi Suite.
If you delete these folders, they will be automatically recreated next time you start Maps, but without content which means you need to redownload any maps and voices that you need.If the Maps spplication is online, it can automatically download map data tiles for the area that you are looking at on the map, but beware because this may incur high data costs if you do not have a fixed-price data plan with your network operator.

  • What are XRE_PATH_POFILE and XRE_PATH_LOCAL_PROFILE used for?

    Can anyone explain how Firefox uses the XRE_PATH_POFILE and XRE_PATH_LOCAL_PROFILE environment variables?
    I recently found a discussion that mentioned them in relation to altering the location of the urlclassifier3.sqlite file. I stupidly failed to note the location of this discussion and now am unable to find it again. (I think it was somewhere in bugzilla.mozilla.org.)
    If I set XRE_PATH_LOCAL_PROFILE before launching Firefox then urlclassifer3.sqlite is relocated to the specified location along with the Cache directory. However I'm looking to deploy this to multiple users and do not want to use it without understanding exactly what is that environment variable is supposed to be used for.
    Google searches for both environment variable names have failed to yield any explanation of what they're used for.

    Hi Wasic,
    all java classes which are needed for the start of weblogic server have to
    be in the CLASSPATH. To this variable belong at least the classes in
    $WEBLOGIC_HOME/lib/weblogic451spXboot.jar and $WEBLOGIC_HOME/classes/boot.
    But there can be more. All classes which have to be loaded by the weblogic
    classloader should only be in a path which you can define by the weblogic
    property "weblogic.class.path". the standard startscript for weblogic server
    uses the environment variable CLASSPATH to define the classpath for the java
    virtuell machine and the WEBLOGIC_CLASSPATH variable to define the classpath
    for the webloic classloader (have a look in the standard script
    "startWebLogic.sh"). EJB´s and servlets should always be in the weblogic
    classpath. You can all weblogic properties like "weblogic.class.path" define
    in the commandline of the jvm with "-D<propertyname=propertyvalue>.

  • What are SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas, when can used?

    Hi everyone,
    I have recently joined in Discussion forums and feeling very excited to read blogs.
    My question is about SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas.
    what are these pragmas and when can we use them?
    It would be greatly appreciated if anyone can answer this.
    Regards,
    Sachin Jaiswal

    Go to http://tahiti.oracle.com, type in your searchwords, choose the database versions you are using and read the results.
    e.g.
    serially_reusable version 11.2
    restrict_references version 11.2
    Also this is not really related to forms, so for this type of question the SQL and PL/SQL forum might be more apropriate:
    PL/SQL
    but as you can see looking up in the documentation brings you answers to your questions in no time ;)

  • What are object and port handles in CAN communication via labview

    Hi,
    I have just started working on the NI labview...i had a problem that when i changed the bitrate using CAN interface create-->CAN SDO create-->CAN write.after that i am not able to communicate with the device with the new bitrate....i have seen a few similiar forums, which talks about object and port handles as an solution of the problems..

    So i want ask that is this object and port handles....

    Thanks your code.
    I try the code you posted, It still no work, I found you has improved the "Get data.vi",It works better,but the second frame still no shown.
    I used the  NI CAN monitor in MAX to monitor the CAN bus,there is no second frame shown in the monitor,See attach pictures.but It shown in the Vector CAN monitor and the code call the Vector DLL.

  • What are advantage and disadvantage for Physical Standy and Logical Standby

    HI,
    What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
    Thanks
    Ken

    Logical standby database
    The key advantage for logical standby databases is that they're opened read/write, even while they're in
    applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
    database. Also, additional indexes, materialized views and so on can be created.
    However (this being a disadvantage) not all datatypes are supported.
    Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
    SQL statements and replays them on the logical standby database.
    Physical standby database
    A physical standby database is a byte for byte exact copy of the primary database. This also means that
    rowids stay the same in a physical standby database environment.
    Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
    physical database.
    A physical standby database might be opened read only; however, the received logs are in this case not
    applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

  • What are SCMRWBS and SCMEMWCL for ?

    Hello all,
    I'm now filling the installation parameter sheet of SCM(APO) system.
    This sheet has two paraemters whose content I'm not sure of.
    That is, software units SCMRWBS and SCMEMWCL.
    What are SCMRWBS and SCMEMWCL for ?
    Do we need to install them while my project will use PP/DS and BP modules ?
    And can we see whether these usage types installed or not via SAPGUI ?
    I beg your help !
    Thank you for your cooperation in advance.
    Regards,

    Hi Hideki,
    SCMRWBS is for SCM Replenishment Workbench. If you are using F&R modules of mySAP SCM suite, then this component is neccessary.
    Smilarly, SCMEMWCL is SCM Web Communication Layer for Event Management. Again this is part of mySAP SCM, but belongs to Event Management module.
    As far as PP/DS is concerned these two components are not neccessary. However, these components may have some dependencies on other applications / modules. Please check with SAP for any specific inputs if you have any concern over installing them onto your system.
    Thanks,
    Rajesh

  • What are strengths and weaknesses of the sap.m.Shell and sap.m.App as container for an application wrapper?

    My question today: What are strengths and weaknesses of the
    sap.m.Shell
    and
    sap.m.App
    as container for an application wrapper?
    I currently use non of them, but I see the advantages.
    SAP best practise is to use one of them or nest them as shell > app. What are strengths and weaknesses of the approaches?

    We prefer to say, the tender mercies of the Fetch block.
    You'll notice the "wfm info" cluster as an output of the Fetch
    VI.  This cluster has gain and offset members- use these to scale
    your binary data to floating point voltage representation.
    As you point out, the numbers won't be exactly what you expect given
    the vertical range and the device resolution.  There are a few
    reasons for this.  First, we don't use the absolute full scale of
    the ADC for the maximum input voltage.  There are a couple of
    codes of headroom at the top and bottom.  This allows your input
    signal to slightly exceed the specified vertical range without clipping
    (you'll get a warning from the driver).  Second, these gain and
    offset numbers take into account calibration information for your
    device.  Using these numbers will correct for small deviations
    from the ideal offset and gain.
    So if you use the gain and offset numbers from the driver, your
    measurements will be more accurate than if you assume 0 offset and
    perfect gain.  They will be most accurate if you make sure to
    perform a self-calibration once the device is in your system and at the
    temperature that your tests will be run.

    u can check the below the material also
    what is BAPI?
    BAPI stands for Business API(Application Program Interface).
    I have answered this question before..
    A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
    You can make your function module remotely enabled in attributes of Function module but
    A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
    BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
    The following standardized BAPIs are provided:
    Reading instances of SAP business objects
    GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
    The BAPI GetList() is a class method.
    GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
    The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
    Create( ) and CreateFromData! ( )
    The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
    Change( )
    The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
    Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
    The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
    Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
    Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.
