How to find the Size of the file ?

Hi,
I have files lying my local machine folder. The file size is huge.
Is there any way to determine the file size, without loading the file data into memory, if we know the filename and the location ?
Appreciate your input.
Regards

you can use the following code:Or even shorter :)
System.out.println("File size = " +new File(filename).length());

How to find the File name using the FTP Adapter

hi all,
how to find the File name using the FTP Adapter with BPEL.
Regards

Found the solution for this.
First In the mediator's routing rule use assign property $in.property.jca.file.FileName to $out.property.jca.file.FileName
In the BPEL's receive activity go to the properties tab and get the property to a BPEL variable. That should do it.
Thanks for the posts

How to find the file that delete from time capsule?

How to find the file that delete from time capsule?

I mean I saved JPEG file in Time capsule and unfortunately delete the file. Can I get it back
IF.... .no other backups have occured since you deleted the file, you might be able to retrieve it using an application like Disk Warrior. It's about $100 as I recall, and there are no guarantees that it will work.
DiskWarrior 4 - The Disk Utility for Mac Disk Repair, Mac Directory ...
Any of the free or low priced utilities that you might see or try will not be able to retrieve a deleted file from a Time Capsule.
If any backups have occured since you deleted the file, the deleted file has almost certainly been overwritten. No way to retrieve it in that case.

How to find the file versions in Oracle applications?

I am requested by the Oracle applications team to check the versions of the following files.
POXWPA6B.pls-115.68.11510.6
POXWPA7B.pls-115.38.11510.7
I have zero experience in managing oracle applications. I would appreciate if some one could let me know how to find the versions in my server. My DB and the applications are in Linux servers.
Also would appreciate if some one could provide pointers to handling Application DBA scenario like this.
Thanks,

Here is an example:
1) /u01/oracle/testappl/po/11.5.0/patch/115/sql>strings -a POXWPA7B.pls | grep -i Header

How to find the file type without the file extension using indesign javascript (.jsx)

hi,
How to identify the file type (eg: InDesign or Quark) without knowing their file type. How can we find what kind of file is that??? without their extension like ('.indd','.qxd') before import to the document...

Hi subha_oviya,
Take a look at the file filtering section in the InDesign CS3 sample script ImageCatalog.jsx to see how to look for file types. I'm assuming that you're using InDesign CS3, and that you're using the Mac OS--you didn't say.
Thanks,

We are interesting in file with maximal values in "field" 2 and 3 assuming that fields are parts of filename separated with "_". I especially created (the file we are interested in) CHECK_300914_215928_xxaa_account_name_20140930201143.txt file to be the first created/modified file.
find . -name CHECK_300914_215928_xxaa_account_name_20140930201143.txt
./CHECK_300914_215928_xxaa_account_name_20140930201143.txt
will definitely work. But we should know the file name. As for topicstarter note it is not the case.
ls -tr . | tail -1
CHECK_300914_200747_xxaa_account_name_20140930195924.txt
gave incorrect file.

HT1199 My iTunes music list all have the exclamation point. I do not know how to find the files to restore the music. Any advice?

All the songs in my iTunes have the exclamation point. I do not know how to find location of the music...any suggestions?

Ok, your music could be in one of a coupel formats, MP3 or, more likely, Apples AAC format, which has a m4a prefix. Open Finder. Hold Command and press F, this will open a search window in the top of Finder. Type mp3 here, let it search. If it finds your music files, double tap on one and "open Enclosing Folder" That should show you where they are at. If nothing is found, try searching m4a instead. One of the two should show you where your music is.

How to find the file by name and identify its type?

Hi,
In a folder thare are many files, the file types are doc, docx, pdf, and rtf. The file name is something like "FirstName LastName(more extrat letters).filetype".
Now I would like to find all the files with a certain name and identify their types. For example, by input "Bill Gates", I would get the list of all files :
Bill Gates.doc, Bill Gates-2010.pdf etc ...
Any good ideas are welcome.
Pengyou

For finding files whose names match a certain pattern, create a FileFilter or FilenameFilter that returns true when the name matches the pattern in question, and then call list() or listFiles() with that filter.
For identifying the "type", that depends what you mean. File's don't actually have a type. It's just that they're interpreted as such in some contexts. The simplest thing is to just look at the extension. You can be more sophisticated than that, but that gets complicated real fast. It depends what you're actually trying to accomplish.

Consolidating itunes media library-how to shorten file names or how to find the file that is creating the problem?

Hi I've switched to Mac for six months now, so is still new to mac and I am using my old 1TB windows PC side by side for my music collection. Now I have seen the posts already in apple community about consolidating itunes music library but could not get the proper way of doing it. My system and itunes is also saying 'file name is too long' and it stops but the questin is how do I know which file is creating the problem and how do I shorten it?
If anybody can answer I'll be obliged to him/her, because its my 6/7 years of music collection stuck in an old pc. Thanks in advance.

By 'it stops' I meant the consolidation process in itunes stops.

How to find the XML file size in the scenarios?

Hi All,
Recently i have attended an interview at a MNC.
They asked some realtime questions like
1.how to find the XML document size in a File-File scenario?
2.What is mass-assignment replication etc.....
Can anybody tell me the solution for these.
Best regards
Hari prasad

If the input is a flat file, there is no exact way to calculate the size of the generated XML file, since it depends on many factors (number of fields in the recordsets, size of the name of the fields, number of records, etc).
As a rule of thumb, generally ppl use XML file size = 2 x Flat file size, in order to do sizing calculations etc. But again, that is just an estimation, not a precise calculation.

How to find the location of java class files at runtime?

Does anyonw have an idea how to get the file name of a java class given the binary name?
I mean how can I get the file name for my class myPackage.myClass?
I am looking for a function which takes "myPackage.myClass" as input and returns
"c:\\javaprojects\\myPackage\\myClass.class".
I tried to do it with the LassLoader class but it did not work. Does anyone have an idea if the Java core API already has a function which does that?
Thanks, Bernhard

Hi ,
It is a simple SAMPLE code , you think and build a logics to handle all classes.
Try this sample, It doesn't handle the inner classes you put logic to handle the logics for inner classes.
The inner class format is it contains the character $ in the File location but inside the code you put "." instedad of "$" you to find out or put trials.

One more option, though not so clean would be use Data Pump and its estimate file size option for the schema. The estimate would tell you the info about the size of the schema.

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.
