篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了c语言中 如何删除文件和重命名文件，举个例子可以么相关的知识，希望对你有一定的参考价值。
函数名: rename功 能: 重命名文件
用 法: int rename(char *oldname, char *newname);
程序例:
#include <stdio.h>
int main(void)
char oldname[80], newname[80];
/* prompt for file to rename and new name */
printf("File to rename: ");
gets(oldname);
printf("New name: ");
gets(newname);
/* Rename the file */
if (rename(oldname, newname) == 0)
printf("Renamed %s to %s.\n", oldname, newname);
else
perror("rename");
return 0;
--------------------------------------------------------
函数名: remove
功 能: 删除一个文件
用 法: int remove(char *filename);
程序例:
#include <stdio.h>
int main(void)
char file[80];
/* prompt for file name to delete */
printf("File to delete: ");
gets(file);
/* delete the file */
if (remove(file) == 0)
printf("Removed %s.\n",file);
else
perror("remove");
return 0;
--------------------------------------------------------
拷贝的话，
要么字节写一个函数；
或者使用 win API： CopyFile

--------------------------------------------------------
/* Chapter 1. Basic cp file copy program. C library Implementation. */
/* cp file1 file2: Copy file1 to file2. */
#include <windows.h>
#include <stdio.h>
#include <errno.h>
#define BUF_SIZE 256
int main (int argc, char *argv [])
FILE *in_file, *out_file;
char rec [BUF_SIZE];
size_t bytes_in, bytes_out;
if (argc != 3)
printf ("Usage: cp file1 file2\n");
return 1;
in_file = fopen (argv [1], "rb");
if (in_file == NULL)
perror (argv [1]);
return 2;
out_file = fopen (argv [2], "wb");
if (out_file == NULL)
perror (argv [2]);
return 3;
/* Process the input file a record at a time. */
while ((bytes_in = fread (rec, 1, BUF_SIZE, in_file)) > 0)
bytes_out = fwrite (rec, 1, bytes_in, out_file);
if (bytes_out != bytes_in)
perror ("Fatal write error.");
return 4;
fclose (in_file);
fclose (out_file);
return 0;
参考技术A int remove( char *path );
int rename( char *oldname, char *newname );
此为正解！
main()
char str[10];
strcpy(str,"test.txt");
if(remove(str)==-1)
printf("remove file error.\n");
else printf("File was removed.\n");
main()
char oldname[20],newname[20];
clrscr();
printf("input oldname:\n");
gets(oldname);
printf("input newname:\n");
gets(newname);
if(rename(oldname,newname)==0)
printf("File was renamed.\n");
else
printf("File rename error");
getch();
PHP 使用按钮下载、删除和重命名文件
【中文标题】PHP 使用按钮下载、删除和重命名文件【英文标题】：PHP download, delete and rename files with buttons 【发布时间】：2016-12-20 07:42:40 【问题描述】：所以我正在使用 php 创建一个小型文件管理器，它将在表格中列出我服务器上一个目录中的所有可用文件，并为我提供下载或删除选项。
这是我的代码：
<html>
<head>
<title>My first PHP Page</title>
</head>
<body>
<iframe id="my_iframe" style="display:none;"></iframe>
<table border="1">
<?php
$dir = 'uploads';
$files = scandir($dir);
sort($files);
$count = -1 ;
foreach ($files as $file)
if ($file != '.' && $file != '..')
$str_URL = "uploads".$file;
echo "<tr>";
echo "<td>";
echo $count;
echo "</td>";
echo "<td>";
echo $file;
echo "</td>";
echo "<td>";
echo "<input type='submit' value='Download'/>";
echo "</td>";
echo "<td>";
echo "<input type='submit' value='Delete'/>";
echo "</td>";
echo "<td>";
echo "<input type='submit' value='Rename'/>";
echo "</td>";
echo "</tr>";
$count++;
?>
</table>
</body>
</html>
我可以列出文件，但无法让“下载”和“删除”按钮正常工作。
非常感谢任何帮助，并在此先感谢您。
【问题讨论】：
你在使用提交吗？你的表格在哪里 【参考方案1】：看我的代码
<html>
<head>
<title>My first PHP Page</title>
</head>
<body>
<iframe id="my_iframe" style="display:none;"></iframe>
<table border="1">
<?php
$dir = 'uploads';
$files = scandir($dir);
sort($files);
$count = -1 ;
foreach ($files as $file)
$v_download = "download_".$count;
$v_delete = "delete_".$count;
$v_rename = "rename_".$count;
if ($file != '.' && $file != '..')
$str_URL = "uploads".$file;
echo "<tr>";
echo "<td>";
echo $count;
echo "</td>";
echo "<td>";
echo $file;
echo "</td>";
echo "<td>";
echo "<form action='' method='post'><input type='submit' value='Download' name='".$v_download."'/></form>";
if(isset($_POST[$v_download]))
// Your php download code here
echo "download file : ".$file;
echo "</td>";
echo "<td>";
echo "<form action='' method='post'><input type='submit' value='Delete' name='".$v_delete."'/></form>";
if(isset($_POST[$v_delete]))
// Your php delete code here
echo "delete file : ".$file;
echo "</td>";
echo "<td>";
echo "<form action='' method='post'><input type='submit' value='Rename' name='".$v_rename."'/></form>";
if(isset($_POST[$v_rename]))
// Your php rename code here
echo "rename file : ".$file;
echo "</td>";
echo "</tr>";
$count++;
?>
</table>
</body>
</html>
