问题 What is the difference between apk size and download size, when I analyze apk in android studio, it always shows me apks size greater than download size, what is the difference. 回答1: According to the APK Analyzer documentation... Raw File Size represents the unzipped size of the entity on disk while Download Size represents the estimated compressed size of the entity as it would be delivered by Google Play. The % of Total Download Size indicates the percentage of the APK's total download size

问题 When performing computer simulations of systems with n (e.g. 10000) particles, the usual workflow involves saving the state of the system frequently at given intervals. This would entail writing down in a file the position coordinates of all the particles (so 3 floats/doubles per line, each line for a particle), with some header information. The floating precision is set to a fixed value. The way I usually save/write down my configuration files is as follows (part of a function that creates

问题 I know I can get file size of FILE * by fseek , but what I have is just a INT fd. How can I get file size in this case? 回答1: You can use lseek with SEEK_END as the origin, as it returns the new offset in the file, eg. off_t fsize; fsize = lseek(fd, 0, SEEK_END); 回答2: fstat will work. But I'm not exactly sure how you plan the get the file size via fseek unless you also use ftell (eg. fseek to the end, then ftell where you are). fstat is better, even for FILE, since you can get the file

问题 I am working on an assignment in socket programming in which I have to send a file between sparc and linux machine. Before sending the file in char stream I have to get the file size and tell the client. Here are some of the ways I tried to get the size but I am not sure which one is the proper one. For testing purpose, I created a file with content " test" (space + (string)test) Method 1 - Using fseeko() and ftello() This is a method I found on https://www.securecoding.cert.org/confluence

问题 I am new to Python. I am trying to input one path and use os.walk() to search all files, and return the files' names. I also want to use os.path.getsize() to get file size, and finally, write them into a csv file. However, if the file name is not in English, but in Chinese, German, French, etc, Python cannot recognize it and does not return the size of the file. I'd like to use os.path.getsize(path) (referring to the example below), but it does not recognize the file's name. How can I let

问题 I'm going crazy trying to get this to work in MinGW 32-bit. It works on all other platforms I've tried. All I want to do is get the size of a > 4GB file into a 64-bit int. This works fine on other platforms: #define _FILE_OFFSET_BITS 64 #include <sys/stat.h> int64_t fsize(const char *filename) { struct stat st; if (stat(filename, &st) == 0) return st.st_size; return -1; } I tried adding the following defines before the above code, based on various suggestions I found online: #define

问题 We're using the following with a 10MB limit for attachments. EXEC msdb..sp_send_dbmail @recipients = 'me@me.co.uk', @subject = 'foo bar', @file_attachments = 'C:\xxx\yyy\myFile.xlsx, @body_format = 'html', @body = 'norf'; Is it possible in the SQL Server scripts to check the size of myFile.xlsx before running this script? 回答1: I have a solution by using Batch Files: [C:\FileSize.cmd] @echo %~z1 Now you can get size of <your_file> by using that file: DECLARE @t table(filesize int) INSERT INTO

问题 I have an Access database, and it is 14 Mb! I really want to reduce the size as I takes a minute to download from the server. I've embedded images as backgrounds on the forms. However, converting the JPG to PNG or GIF doesn't seem to reduce the file size at all. Compacting also doesn't do much. Please advise if anyone knows how to reduce the file size significantly Thanks!! 回答1: The answer is simple: Move the pictures off the database to separate files. That said, 14 MB isn't really that much
