从选定的文件夹中获取文件列表，文件夹大小> 100MB，路径目标为c [英] Get the list of files from selected folders having sizes >100MB with their paths objective c

问题描述

我想获得所有文件的列表及其路径&

$ b

$ b b

我使用下面的代码得到了系统的大小。

  NSError * error; 
 
 NSFileManager * fileManager = [NSFileManager defaultManager]; 
 NSDictionary * fileAttributes = [fileManager attributesOfFileSystemForPath：@/error：& error]; 
  

现在我想得到文件列表及其路径和大小。

我搜索了很多，但是那些不能满足我的要求。

请求帮助我。

提前感谢...

解决方案

我有以下情况的解决方案。

感谢 CRD 给我这个想法。

首先，我走了一个文件夹的路径。然后为了得到子文件夹，我使用 NSDirectoryEnumerator ，然后我使用代码来查找文件的大小。

一旦我得到文件的大小，然后检查文件大小并添加到我的数组。

NSString * Path = [NSString stringWithFormat：@/ Users /％@ /，NSUserName（） ];

NSDirectoryEnumerator * de = [[NSFileManager defaultManager] enumeratorAtPath：Path];

NSString * file;
NSMutableArray * arrList = [[NSMutableArray alloc] init];

while（（file = [de nextObject]））
NSLog（@file％@，file）;

Path = [NSString stringWithFormat：@/ Users /％@ /，NSUserName（）];

Path = [Path stringByAppendingString：file];
NSLog（@path％@，Path）;
NSError * attributesError = nil;

NSDictionary * fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath：Path error：& attributeError];

NSNumber * fileSizeNumber = [fileAttributes objectForKey：NSFileSize];
long long fileSize = [fileSizeNumber longLongValue];
NSLog（@％lld，fileSize）;

float sizeKB =（（float）fileSize / 1000）;
NSLog（@％f，sizeKB）;

float sizeMB =（（float）fileSize / 1000000）;
NSLog（@％f，sizeMB）;

if（sizeMB> = 100.0）
{
[arrList addObject：file];
[test addObject：file.lastPathComponent];
}

希望它也能帮助别人。

I want to get the list of all files with their paths & sizes for my mac system.

From that, I want to filter only those files which have file size above 100 MB.

I got the size of my system using the below code.

NSError *error;

NSFileManager *fileManager = [NSFileManager defaultManager];
NSDictionary *fileAttributes = [fileManager attributesOfFileSystemForPath:@"/" error:&error];

Now I want to get the list of files with their paths and sizes.

I searched a lot but those couldn't meet to my requirements.

Pleas help me on this.

Thanks in advance...

解决方案

I got my solution with the following scenario.

Thanks CRD for giving me the idea.

First, I took a path of a folder. Then for getting subfolders only, I used NSDirectoryEnumerator and then I used the code to find the size of file.

Once I got the size of the file, then I checked the file size and added to my array.

So it worked.

NSString *Path = [NSString stringWithFormat:@"/Users/%@/",NSUserName()];

NSDirectoryEnumerator *de = [[NSFileManager defaultManager] enumeratorAtPath:Path];

NSString *file;
NSMutableArray *arrList = [[NSMutableArray alloc]init];

 while ((file = [de nextObject]))
 NSLog(@"file %@",file);

 Path = [NSString stringWithFormat:@"/Users/%@/",NSUserName()];

 Path = [Path stringByAppendingString:file];
 NSLog(@"path %@",Path);
NSError *attributesError = nil;

 NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:Path error:&attributesError];

 NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
 long long fileSize = [fileSizeNumber longLongValue];
 NSLog(@"%lld",fileSize);

 float sizeKB = ((float)fileSize / 1000);
 NSLog(@"%f",sizeKB);

 float sizeMB = ((float)fileSize / 1000000);
 NSLog(@"%f",sizeMB);

 if (sizeMB >= 100.0)
 {
     [arrList addObject:file];
     [test addObject:file.lastPathComponent];
 }

Hope it helps someone else also.
