filesize

A newbie question but I have googled abit and can't seem to find any solution. I want to allow users to directly upload files to S3, not via my server first. By doing so, is there any way the files can be checked for size limit and permitted types before actually uploading to S3? Preferably not to use flash but javascript. stonyau If you are talking about security problem (people uploading huge file to your bucket), yes, You CAN restrict file size with browser-based upload to S3. Here is an example of the "policy" variable, where "content-length-range" is the key point. "expiration": "'.date(

I'm using this function to convert a file size in bytes to a human-readable file size: function getReadableFileSizeString(fileSizeInBytes) { var i = -1; var byteUnits = [' kB', ' MB', ' GB', ' TB', 'PB', 'EB', 'ZB', 'YB']; do { fileSizeInBytes = fileSizeInBytes / 1024; i++; } while (fileSizeInBytes > 1024); return Math.max(fileSizeInBytes, 0.1).toFixed(1) + byteUnits[i]; }; However, it seems like this isn't 100% accurate. For example: getReadableFileSizeString(1551859712); // output is "1.4 GB" Shouldn't this be "1.5 GB" ? It seems like the division by 1024 is losing precision. Am I totally

why is the output of du often so different from du -b ? -b is shorthand for --apparent-size --block-size=1 . only using --apparent-size gives me the same result most of the time, but --block-size=1 seems to do the trick. i wonder if the output is then correct even, and which numbers are the ones i want? (i.e. actual filesize, if copied to another storage device) Apparent size is the number of bytes your applications think are in the file. It's the amount of data that would be transferred over the network (not counting protocol headers) if you decided to send the file over FTP or HTTP. It's

I need a way to get the size of a file using C#, and not the size on disk. How is this possible? Currently I have this loop foreach (FileInfo file in downloadedMessageInfo.GetFiles()) { //file.Length (will this work) } Will this return the size or the size on disk? Marcin Deptuła FileInfo.Length will return the length of file, in bytes (not size on disk), so this is what you are looking for, I think. If you have already a file path as input, this is the code you need: long length = new System.IO.FileInfo(path).Length; FileInfo.Length will do the trick (per MSDN it "[g]ets the size, in bytes,

In my site host, I have seen (via phpinfo) that post_max_size = 8Mb upload_max_filesize = 16Mb This led me to think that I should be able to upload as file as big as 16Mb. However, when I do this through a post method (as normal), post_max_size takes over and declares that I sent too much. What is the method which permits sending a file as big as 16Mb ? GET - PUT - other ? Hope someone can clarify this for me. Simon Matthew upload_max_filesize is the limit of any single file. post_max_size is the limit of the entire body of the request, which could include multiple files. Given post_max_size =

I want to have a batch file which checks what the filesize is of a file. If it is bigger than %somany% kbytes, it should redirect with GOTO to somewhere else. Example: [check for filesize] IF %file% [filesize thing Bigger than] GOTO No echo Great! Your filesize is smaller than %somany% kbytes. pause exit :no echo Um... You have a big filesize. pause exit If the file name is used as a parameter to the batch file, all you need is %~z1 (1 means first parameter) If the file name is not a parameter, you can do something like: @echo off setlocal set file="test.cmd" set maxbytesize=1000 FOR /F
