I have a zip file on a server.
How can I check if the file size is larger than 27 MB?
File file = new File("U:\intranet_root\intranet\R1112B2.zip");
if (file > 27) {
//do something
}
Use the length()
method of the File
class to return the size of the file in bytes.
// Get file from file name
File file = new File("U:\intranet_root\intranet\R1112B2.zip");
// Get length of file in bytes
long fileSizeInBytes = file.length();
// Convert the bytes to Kilobytes (1 KB = 1024 Bytes)
long fileSizeInKB = fileSizeInBytes / 1024;
// Convert the KB to MegaBytes (1 MB = 1024 KBytes)
long fileSizeInMB = fileSizeInKB / 1024;
if (fileSizeInMB > 27) {
...
}
You could combine the conversion into one step, but I've tried to fully illustrate the process.
