Problem Copying Large Path Files

Some time ago I saw one problem as a consequence of a project, this consisted on moving all directories from one network device to an external drive as a backup policy. But, during the copying process happened problems with certain directories and files, an unknown error actually.

However, I got the impression that this problem could be produced by the large length of the paths of this directories or files and yes, that was the reason.

As a proof of this, I created a large path for a directory that just contains one text file, as you can see "D:\Large Named Directory" has a lot of similar inner directories, having the last one the "Large Named Textfile.txt" file. Pay attention, because it's not possible to create more directories inside the last one, because Windows has a limit... like everything in life.

Now, the image showed before represents the directories in the network drive, and we are going to copy them to a new directory located in the "local drive" which is represented by "D:\Another Large Directory to Copy Directory" directory, but when we do this simple procedure, we get this error message.
 
Error when trying to manipulate the last folder

All of this because the file in the first location had a full path with less than 256 characters, however, in the new location it would have needed a full path with more than 256 characters which is not allowed by Windows. So, what you have to do in this situation is changing the path directory destination to the shortest name to not exceed the 256 path length limit.

I Need to Send an Automatic Email with Lotus Notes

Image
If you don't know, Lotus Notes is an email client used in a lot of companies around the world. Therefore, I use it at work everyday, but someday I needed to send an automatic email to a few people all Fridays at 10:00.   To get this task accomplished I decided to create an agent and avoid remembering the fact of sending the email. As you can image, I did this example on a Spanish version of Lotus Notes 8.5 but I will explain it clearly enough. The first step is getting yourself into the inbox, then select the "Create" menu item and inside of it, click on "Agent...". You will get a dialog box opened, in this we have the possibility of setting the rules for this agent. However, in this case we will only set "Trigger" option to "On schedule" with the "Weekly" frequency. Don't forget to push the "Schedule..." button to program the agent in the right way. After this, select "OK" and close the dialog bo...

Turn Horizontal Visio Swimlanes into Vertical Ones

Image
In one ocassion, a friend at work called me because she had a problem with Microsoft Visio , she was trying to draw a process flowchat but using swimlanes, this was not a problem until she realized that it would be better to use vertical swimlanes instead of horizontal ones.    But, when she tried to drag a vertical one it just put together to the previous swimlanes created before.  To avoid creating a new visio document and lost your work just go to 'Cross-Functional Flowchart' ribbon and select 'Orientation' and 'Vertical'.     And it's done, now you can work with vertical swimlanes or if you like it you can turn them back to horizontal ones.
