How do I know the size of a file

Hi,
Would anybody please show me how to get the size of a file. for example, I create a file like this
FileInputStream FINPUT = new FileInputStream ("c:\\testing.prn");
I need to know the size of FINPUT before using it but I don't know how.
note: It is not neccessary to use FileInputStream. I can use any stream or file that allow me to check the size and read out the data from the file byte by byte.
Thanks a lot.
Hung

Thank you for your responding. But, how can I read out the data? I need to read the data from the file byte by byte.
Thanks
Hung.

Inputs are welcome !

How to know the size of a DB ?If you want to know the physical size, query dba_data_files + dba_temp_files. if you need to know the actual consumed space in those files, compute sum of bytes from DBA_SEGMENTS.

How to know the size of a webservice request

Hello...
I'd like to know if you know how do I get the size of a Web request? I mean, I need to know the size of a Web Request 'cause I'll fill a Gauge Object up based on the quantity that I have received from the WebService.
I'm using the KSOAP and KXML API's for consuming that WebServices and I used the Content-lengh Method and it didnt return anything to me... it returned empty. So, do you know how do I fill a Gauge Object based on the size of the WebRequest? Could you tell me some examples plz?
Thanx...

How to determine the size of a file on application server

Hello,
using open dataset I have created a file on the application server and have put some data into the file.
Now I want to know the size of this file.
Is there a function module to do this ?
Best regards
Michael

Hi,
Use Function module   'EPS_GET_FILE_ATTRIBUTES'
DATA fsize TYPE epsf-epsfilsiz.
CALL FUNCTION 'EPS_GET_FILE_ATTRIBUTES'
EXPORTING
    file_name =     " here provide filename
    dir_name =    " here provide directory
IMPORTING
    file_size = fsize.
WRITE: 'File size' , fsize.

How to know the size in bytes of a directory?

I would like to know if there's a class or a function which allows to know the size of all files in a directory?

You have to create a File object for your directory, then list all files (using the list() method) and create a File object for each item returned. Then ask each File object for it's size and add them up.

How to know the size of bad sector block after zero out erase?

I found some problems on my USB external harddisk recently. After I backup all the files, I erased the whole volume by choosing "zero out data" option. According to some web articles, "zero out" detects and marks those bad sectors to avoid further read/write action on the damaged area.
My question is that how can I know the size of disk space marked as bad sector? Because I can only see how many space is used or available when I check a disk in disk utility. There are about 600MB used for my 1TB hard drive. I guess there is some storage used by spotlight or other hidden files. But I have no idea for how many MB is occupied by bad sector...

Yes you can look at see the original number of spares, the number used, and the number remaining spares.
Disk Warrior for one, writes the SMART data to system.log Other programs can also read and report (not sure which if any write to system.log though) those field values from SMART table entries.
IF the number of spares is declining, time to replace. Trouble is OS X hasn't had a good record of reporting I/O errors, let alone remapping. Some 3rd party utilities will. I've found the vendor (WD, Hitachi etc) have the best utility for their own drives, but those are Windows programs or LinuxCD. Also the best way to zero and map out bad sectors, too.

How to know the size of archived logs created under ASM

I using Oracle 10g on Linux x86-64.
I need to ship the archived logs(not the entire directory, only a few) from the Live database to the DR site, so I need an estimate of how much time it will take to ship them across the network ?
Is there anyway I can know the size of a specific archived log file stored under ASM ?
We can use du in ASM to know the size of directory but I dont find a command in ASM to get the size of a file ?

No we are also switching logfiles manually , so the maximum size may not
have reached.
What I need is something like ls -l command in the Unix prompt which will
help us to find the size of the file , a similar command to help us determine
a size of file in ASM ?What is the objective?
Anyways, you can get the size of an archived log file by quering V$ARCHIVED_LOG view.
SQL> select sequence#, name, blocks*block_size from v$archived_log where sequence# > 180;
SEQUENCE# NAME                                     BLOCKS*BLOCK_SIZE

How to change the size of redo file

Deal all,
I finish installed the db,and the size of redo file is 50m by default. I found many "checkpoint not complete" events in alert.log file.
Now i want to change it to 100M and try to avoid the event appear again ,how can i do?

As Sb has already correct reply that size of redo logs can not be changed. We have to create new bigger/smaller size of redo logs and then 'alter system switch logfile' to inactivate older logs. Now you can drop older logs. Redo logs are something a glass of water. We can not change the size of glass, if we wish to dring more/less water, we will take that sized glass and we will get that sized water.
Remember to consider the multiplexing/grouping when doing any maintenance like this. And there may be archive log & backup space considerations.

How to know the size of the EEPROM after loading any Applet

How can I know the size of the EEPROM after loading any applet..
Any comments on this is appreciated
Thank you in advance

Thanks for your suggestion.
But when I try to use
short memRemaining = JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_PERSISTENT);
it always shows 32767. Even after loading some applet.
And I am using 72K Java card then how it can show only 32Kbyte as the remaining memory value.This is because a short isn't big enough to display a number above 32767. One way around this is to use a byte[] to fill up some of the space with your temporary applet.
byte[] memoryFiller = new byte[32767];
short memRemaining = JCSystem.getAvailableMemory(JCSystem.MEMORY_TYPE_PERSISTENT);The value of memRemaining + 32767 is the amount of persistent memory left on the card. If memRemaining is still 32767, you can add another byte[] starting with small values and increase the size until you get a meaning ful result (less than 32K).

How to know the size of data in some columns of a table?

Hi,
How can the size of of data for some specified column be determined?
For example : TableA has 20 columns and the size of table is 20 GB. I want to know the size of data kept in last four columns.
Thanks in Advance,
Vishu

You could use vsize to determine the size of a column element and sum them upselect sum(vsize(column_of_interest)) from whatever_table;

How to find the size of a file or folder

How can I find the size of a file or folder?
I am trying to determine the size of my iPhoto and Mail folder.
It says "Size: --" under general from Get Info.

It's working fine...
When you ask for that info, and Finder presents those '--' dashes instead of a value, actually, Finder is calculating the value in background.
That's something that i recently noticed and wonder why tha heck he needs to do all that work by himself, kinda re-inventing the wheel of file size value "calculus"...
I posted some thoughts about it here: File / Folder size... How do Finder gets it?
Will appreciate feedback about this!
Props!

How to know the size of a message I wrote

When I created a photojournal, with comments before each photo, I got a message "The size of the message you are trying to send exceeds the global size limit of the server."
So it was not sent and I was told to reduce it and try again. I did that with the photos, deleted a few, as well, but still got the error message, and have not discovered how to find the size of the message.

save it to drafts.
in the drafts folder, click on the little table widget right on the right side of the column headings... select size
Remember size increases about 30% for attachments.
