this works for me… using System.IO; private long GetTotalFreeSpace(string driveName) { foreach (DriveInfo drive in DriveInfo.GetDrives()) { if (drive.IsReady && drive.Name == driveName) { return drive.TotalFreeSpace; } } return -1; }
Python Object Data Size If the data is stored in some python object, there will be a little more data attached to the actual data in memory. This may be easily tested. It is interesting to note how, at first, the overhead of the python object is significant for small data, but quickly becomes negligible. … Read more
You can use the CURLOPT_COOKIEJAR option, and set the file to “/dev/null” for Linux / MacOS X or “NULL” for Windows. This will prevent the cookies from being written to disk, but it will keep them around in memory as long as you reuse the handle and don’t call curl_easy_cleanup().
Example: Getting human readable size like 1 Gb String memory = bytesToHuman(totalMemory()) /************************************************************************************************* Returns size in bytes. If you need calculate external memory, change this: StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); to this: StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath()); **************************************************************************************************/ public long totalMemory() { StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); long total = (statFs.getBlockCount() * statFs.getBlockSize()); return total; … Read more
You need to check the HResult and test against ERROR_DISK_FULL (0x70) and ERROR_HANDLE_DISK_FULL (0x27), which can be converted to HResults by OR‘ing with 0x80070000. For .Net Framework 4.5 and above, you can use the Exception.HResult property: static bool IsDiskFull(Exception ex) { const int HR_ERROR_HANDLE_DISK_FULL = unchecked((int)0x80070027); const int HR_ERROR_DISK_FULL = unchecked((int)0x80070070); return ex.HResult == HR_ERROR_HANDLE_DISK_FULL … Read more

In general if you don’t need to shrink your datafiles you shouldn’t shrink them at all. This is because “growing” your datafiles on disk is a fairly expensive operation and the more space that MongoDB can allocate in datafiles the less fragmentation you will have. So, you should try to provide as much disk-space as … Read more
this post might fit well to your question. also check this thread. there is so much info here on SO. googled a bit and here is the solution (found at android git) File path = Environment.getDataDirectory(); StatFs stat = new StatFs(path.getPath()); long blockSize = stat.getBlockSize(); long availableBlocks = stat.getAvailableBlocks(); return Formatter.formatFileSize(this, availableBlocks * blockSize);
This doesn’t give the name of the partition, but you can get the filesystem statistics directly using the statvfs Unix system call. To call it from Python, use os.statvfs(‘/home/foo/bar/baz’). The relevant fields in the result, according to POSIX: unsigned long f_frsize Fundamental file system block size. fsblkcnt_t f_blocks Total number of blocks on file system … Read more
Have a look at the File class documentation. This is one of the new features in 1.6. These new methods also include: public long getTotalSpace() public long getFreeSpace() public long getUsableSpace() If you’re still using 1.5 then you can use the Apache Commons IO library and its FileSystem class
