What else can I help you with?
Linux command to create myfiletxt in the DATA folder?
You want to do that from command line? Create folder DATA with mkdir DATA. (You should have permissions to create it) If you want to create an empty file, just say touch DATA/myfile.txt Or you can use the vi editor to write to the file (vi will open the file if it exists else will create that file for you), just type vi DATA/myfile.txt You may need to learn some vi keys before you try that. On Linux, try vimtutor! And just in case you think it is boring to type DATA/something... do CD DATA after creating the directory (folder) . Enjoy :)
How do you insert data in middle of file in java?
One way to do it would be as follows: * Read the entire file to a String variable * Write the data before the insertion point * Write the data to be inserted * Write the data after the insertion point Probably the following would be more efficient: * Read the part of the file after the insertion point, to a String variable * Write the data to be inserted * Write the data after the insertion point Perhaps some classes have methods that can automate this, from the point of view of the programmer. But if you want to INSERT something, it's unavoidable to have the overhead of reading the data after the insertion point, and writing it back again. This assumes you use a text file; when working with a database, there are other, usually more efficient, options.
What are the advantages of a file management system?

If you do not have write access to the file and you are not the owner, then you cannot write to the file with a program running as some other user. Although, setting the setuid bit on the executable of a custom helper program or daemon might be set up in some fashion to do what you want.

Why are data translation utilities of use?
Some programs can only use certain file types. Data translation changes the file type to a type that is usable by the program.
What are disadvantages of file system?
File system data management (or flat-file databases) served as the only method of file storage and retrieval before the advent of database management systems (such as relational databases). While retaining some use, flat-file databases suffer from poor accessibility, data redundancy, lack of standard file access and the inability to organize data.
What is a differences between application and file?
