Adding extensions in bulk

I'm pulling some really old files which were originally on an old Mac running Mac OS 8.6.
They are text files, but do not have the extensions because HFS & HFS + has a file type that ID metadata it as TEXT (no doubt with the creator ttxt).

Is there a quick and easy way to add a .txt extension to 67 all files in the directory?
I tried ren *. *.txt but I got the error "the syntax of the command is incorrect."

(Windows XP, Vista, 7, 8)

Bulk Rename Utility tutorial
http://www.bulkrenameutility.co.UK/tutorial.php

Download and install the utility... (you can uncheck not...
'Install the Extension of Windows Explorer' and 'install
Samples)

Once installed... Open the program and in the upper left
pane, drill down to the folder your files are saved in.

When you select the folder, the file names should
appear in the upper right. (You will notice... There is a)
"Name" column and a "New name" column... so you
can see the changes that will apply.

First... to... Actions / select all... (you will not see
changes and you can't rename files unless
are selected / highlighted)

In the 'Extensions (11)' section of the screen... Open
the window menu and choose 'fixed'... now type your
new extension in the field empty.

When the column new name seems correct... left click
the button "Rename"... then... OK / OK.

The name change occurs instantly.

FWIW, you can experiment with a few samples
(copies) first just to get oriented with the user interface.

  • Adding extension to Interface to 4235 4FE - requirements, warnings?

    I'm under version 4.1 (1) S48 on 4235 sensor.

    I want to monitor two separate subnets in the DMZ with a sensor. 4.1 supports several interfaces of promiscuity, it seems that the addition of the 4FE interface card support this well. Bandwidth is not really a concern, these connections are not heavily used T - 1 connections.

    My questions are related to the impact on the sensor. Will there be additional requirements of memory/CPU by adding more surveillance interfaces? I noticed that it also seem to be a new plug-in memory available for sensors, I was wondering if this is related?

    From a point of view of configuration, I assumed that, for the moment, the same signature settings will be applied to all virtual devices (virtual sensor is equivalent to a physical interface of remote sensing)? It is very good for the current application, but I wonder if it is will be supported for different signature by virtual sensor parameters in the future?

    Any reserves, traps, etc. that you can share on the displacement of several interfaces of remote sensing would be appreciated.

    Thank you

    Chad

    Traps to keep in mind:

    4FE card is attached to four 10/100 ports. The standard onboard sniffing port is a 10/100/1000. So be aware of the limit of 100 Mbps on FE 4 10/100 ports.

    Since you are dealing with only T1 lines that won't be a problem for you.

    The performance of the IDS-4235 is based on the total bandwidth of all interfaces combined.

    If I remember correctly the IDS-4235 performance rating is about 250 Mbps.

    So let's say that you plug in 3 interfaces of the 4FE, then 3 interfaces could send up to 300 Mbps of traffic and overwhelm the sensor performance.

    It could be worse if we consider the 1000 Mbps card on board. So, theoretically with all 4 plugged FEs and the edge sniffing plugged as well, you could theoretically send 1.4 Gbps of traffic to this sensor years 250Mbps seriously overwhelm.

    In you case to connect only 2 ports currency limit you the total maximum rate 200 Mbps (still more low whereas you have T1 connections) so it will not be a problem for you, with performances of the 4235 250 Mbit/s.

    With regard to the other CPU/memmory. There is no additional CPU or available for the 4235 memmory. The additional memmory was only for old models of 4210 and 4220.

    You do not need anyway. 250 Mbit/s performance is based on the provided memmory and cpu regardless of the number of interaces since it's overall performance and not by the performance of the interface.

    When version 4.1 is loaded with the 4FE each of the interfaces is usually attributed to "interface group 0" and default is off (stop). You should make sure that the interface you are using are indeed assigned to the "interface group 0" and then activate the interfaces that you want to use (no downtime).

    You are right to assume that version 4.1 supports a single virtual sensor (single set of configurations of signature) which is applied to all interfaces.

    Indeed the virtual sensor is applied to "interface group 0" and all interfaces are placed in group 0. The only group 0 is currently supported for a single virtual sensor is currently supported.

    Support for multiple virtual devices / groups is planned for a future release (could not begin to speculate when that can happen).

    Since a single virtual sensor is used, it is sometimes confusing determine on what interface things occurred.

    Each event lists on which interface the packet that triggered the alert has been detected. SO for example with a sweep of ping host first 4 pings can be seen on an interface but the 5th ping that triggers the alert can be seen on the second interface; This translates into the second interface in the alert.

  • Help adding extensions to a VMFS data store

    Hello people,

    I am working on some automation for creation of data store and must be able to add extensions to a data store.  The initial creation of data store works well enough at this point, but I'm a little puzzled about how to add additional extensions.  In my example, I am using the navi cli to make the LUN UID off the coast of the Bay of EMC, then format it correctly for the canonical name the host for the creation of data store.

    I read a little about the extendvmfsdatastore here , but I am not able to separate the part "add the measure" of "questioning the existing data store and remove references to pass."  If someone has an extract whose orders must be performed and the text to pass to the .extendvmfsdatastore method, I'd be very happy.  I know measure in several data stores fall into disgrace with VMware, but I can't migrate 10TB data storage immediately.

    Thanks in advance!

    I went to add ons site and then tried to install one and there was a message adding extensions had been disabled and I want to enable it. I enabled and the option was available on the addons tab. Although I don't know why it has turned off by itself first.

  • extensions are available for IOS, but not mac os, why?

  • HP Touchsmart 520: changed file extensions

    After the last update on windows 7, all my file names have added extensions for them. For example, Alien has changed to Alien.mkv. Each video, the song and the document on my computer did. If I plug in an external hard drive, it changes too. Any ideas how to change their return other than to do it manually for each file? I get a warning also that the file may not work if I change.

    Hello

    Extensions are usually hidden by default (but should not be changed or deleted), in order to check the following.

    On the Start Menu, open the control panel and open Folder Options.  Click the view tab and make sure the box next to the entry "Hide extensions of known file types" is checked.  If you need to enter a check mark against this article, click on apply then Ok to save the change.

  • How to combine the extensions repository

    I have a core Appassure 5.4.3 with a 50 to deposit composed of nine degrees. Is there a documented procedure I can follow to combine scopes to only one? I'm afraid that with nine extents (nine different data and metadata locations) my performance is reached. It may take some time to mount a volume from this repository.

    In the application there is not a way to consolidate the scopes by adding extensions is a travel one-way. From 9 to 7 degrees, or down to none is not an option built in... The ways to do this would include additional hardware to accomplish this task, either in the form of new core and new repo, or just a new repo.

    You could archive data from existing repo agent or two at a time and put it on the repo again, however, you will need to have a separate repo available configured the way you want.

    support.Software.Dell.com/.../119953

    Or you could raise another kernel & repository and migrate data off the coast through replication.

    documents.Software.Dell.com/.../Roadmap-for-setting-up-Replication

    To answer your question though, no, it's not a way of the product now to reduce the number of extensions without additional resources. If they are on different forms of storage and/or different speeds of disks so I agree with you your performance could suffer. If they are comparable technologies and/or speed the decline in performance should be minimal.

  • Update of table after SELECT COLLECT in BULK IN

    Hello


    I have the following query

          SELECT TYPE(A, B, C, D)
          BULK COLLECT INTO ARRAY_TYPE_VAR
          FROM table
          WHERE ROWNUM <= number;
    

    And after execution of this I need to update the selected lines to mark as processed.

          UPDATE table
          SET is_proc = 'Y'
          WHERE ...
    

    -I want to just select a predefined number of lines (ROWNUM < = number)

    -Selected data comes from an intermediate table that I can't control and there is no PKs.

    Is it possible that I can use to identify the selected lines and use them in an UPDATE statement?

    Thank you

    I need to select the data to perform certain operations and validations and insert in the paintings of application.

    Since I have a large number of files, I found myself with performance while loading problems all in memory.

    I am trying to create a kind of limiting process:

    Until I have 0 not dealt with the lines:

    Select lines of high x-> perform data operations-> lines of the selected mark as processed

    The sql code I posted is inside a loop.

    I'm probably complicate an easy problem, but I'm kinda stuck with it.

    And Yes, there is a column that can be used to identify the data.

    There is NO NEED to 'Butterfly' lines of process or as treated brand.

    Assuming that you need to use the collections and PL/SQL just treat ALL lines but only a limited number at the time.

    Some examples of code (ONLY for the demonstration) which deals with the entire EMP table a few lines at a time:

    EXTRACTION is a BULK of COLLECTING all the data in "v". It will get either all data, or none if there is none.

    The construction of the LOOP would be used when you have a LIMIT clause while Oracle would be 'loop' return to
    Download the following set of lines. Run this example in the SCOTT schema and you will see how the LIMIT clause.
    I have 14 rows in my table EMP.

    DECLARE
    CURSOR c1 IS (SELECT * FROM emp);
    TYPE typ_tbl IS TABLE c1% rowtype;
    v typ_tbl;
    BEGIN
    OPEN c1;
    LOOP                                                 --Loop added
    C1 FETCH BULK COLLECT IN v LIMIT 3; -treat 3 records at a time
    -treat the first 3 max records
    DBMS_OUTPUT. Put_line ('Treatment' | v.COUNT |) "documents.");
    I'm IN v.first... v.Last LOOP
    DBMS_OUTPUT. Put_line (v (i) .empno);
    END LOOP;
    OUTPUT WHEN c1% NOTFOUND;
    END LOOP;
    DBMS_OUTPUT. Put_line ('all done');
    END;

    In the loop, you would do any processing of the nested table, you want to make
    and could use a FORALL do one INSERT into another table.

  • Cursor Bulk Collect

    Hi all
    I have a doubt about cursor in block collection. Both versions work correctly.

      TYPE typ_tbl IS TABLE OF c1%rowtype;
      v typ_tbl;
    BEGIN

      CLOSE c1;
      FOR i IN v.first..v.last
      LOOP
        DBMS_OUTPUT.PUT_LINE(v(i).t2);
      END LOOP;  
    END;
    
    2nd version: 
    DECLARE
      CURSOR c1 IS (SELECT t2 FROM test10);
      TYPE typ_tbl IS TABLE OF c1%rowtype;
      v typ_tbl;
    BEGIN

      LOOP
        DBMS_OUTPUT.PUT_LINE(v(i).t2);

    Is it necessary to have a loop and exit the statementwhen notfound cursor used with bulk collect?

    But in doing so, context switches will be more aint't it?

    Yes, you will need to switch between SQL and PL/SQL, which is one of the penalties you pay to use the PL/SQL when SQL is necessary (don't tell is your case here, just a generality). However, that there are compromises. Memory is a limited product, it is expensive and you do not have an infinite amount. It is not as effective to spend many thousands of records in memory and then apply to processes that together, if you bulk load a bit, process a little you avoid exhaust any given resource (CPU, memory, etc...).

    As I said, Oracle will use a fetch array of 100, instead of X, where X is the number of records your query when you use a bulk collect without LIMITS. If you had to carry 10 000 magazines across the room, do you think you would sooner do 100 at a time and do a lot of travel or find a way to carry all the 10,000 in a trip?

    If you are interested in the analysis comparative differences, set up a simple table and load 100,500,1000,10000,100000, etc... documents in it and see what look like processing times.

    For versatile use, the implicit cursor loop wins hands down for each perspective (my opinion). Yet once again, assuming that you NEED pl/sql at all.

  • Missing Basic code editor tools? Extensions?

    Is there really no batch search / replace, replacement of GREP or autocompletion HTML element? Assume that this 'new' tool could perform at least at a level of the code editor DW CS3 (or earlier?) could... like the idea of the editor of related files in place, but without these basic features I'm back to BBEdit for now.

    Also: thought maybe adding extensions would extend the feature, but there seems to be none? Is there a resource somewhere, like the forum of Code returns 0 results like Google.

    Hi Aaron,

    Well, there is a reason we call it a "preview release" rather than "1.0" :-)  There are a lot of features that are not thre or are not completely polished yet... but actually many things you mentioned already exist:

    • 'Replacement of GREP' - I assume you mean search - replace using a regular expression?  If you open the replacement bar you can use regular expressions (note the label beside the input field to describe the syntax "/... /").
    • Element HTML reference code - you should get the code hints for the names of tags and attribute names.  If you don't see that, you can share your HTML file so that we can investigate on?
    • There are also indicators in the last Edge Code, CSS code fwiw.  And there are indicators in the bext JS code release.
    • The extensions are listed on the main page of the opensource project, here: https://github.com/adobe/brackets/wiki/Brackets-Extensions.  We are working on the construction of navigation/install extension more polished experience, however.

    The only thing on your list that is missing is find-replace in many files at once.  You can track our progress on this or upvote user here, in our Trello backloghistory.

    Hope that helps,

  • Save as extensions scrambled on PS CS6 Mac Lion

    When I select Save as after editing a file as a PSD brouight or RAW file if I choose TIFF as the type of file, the added extension is PNG. If I choose JPEG extension is esd. I've just updated to be sure to have the latest version. The connection between the finder and photoshop does not seem to be working properly. Another example, when I choose to open a file menu which opens requires all first select the type of file I want to import before it will allow me to select a file type. There is no default.

    You have copied a previous version of Photoshop plugins and plugins in doubles are at the origin of the problem.

  • Why is the video from popular websites (for example Weather Channel) blocked on my Firefox?

    I recently downloaded Firefox on a PC, it is my default browser, and everything worked fine. I added extensions including Ghostery and add block more that work very well on my other browsers and I think on Firefox for a while. Now I can't get the video to work on popular websites (e.g., the Weather Channel), even if I disable Ghostery and add block more that I don't think that is the problem anyway. So I messed up something. Any thoughts would be appreciated.

    A frequent cause of script errors does not work on sites that use Flash is the feature of mode of the Flash player plugin. This feature has the security benefits, but it seems to have serious compatibility problems on some systems. You can disable it using the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. On the right side, find 'Shockwave Flash' and click on the link for more. Then uncheck the box for "Enable Adobe Flash protected mode" and try it for a day to see if that helps you.

    The Cowboys site certainly uses Flash. Do you get the commercial of the pre-roll for Dallas advertising or no video at all?
