5.10 6.00 6.00a 6.00ax 7.00 | 1.00 1.50 MS-DOS | WINDOWS kbprg kbcode -- The information in this article applies to: - The C Run-time (CRT), included with: - Microsoft C for MS-DOS, versions 5.1, 6.0, 6.0a, and 6.0ax - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, versions 1.0 and 1.5 -- SUMMARY ======= When using the remove function to delete files, passing a wildcard as an argument to remove does not delete any files. To delete all the files in a directory, use the _dos_findfirst and _dos_findnext functions to search for each file; then use the remove function to delete each file. The sample code below demonstrates how to write a code equivalent to remove(&quot;*.*&quot;). Sample Code --- #include #include #include main { struct find_t c_file; char fn[12]; printf (&quot;Enter file to delete: &quot;); scanf (&quot;%s&quot;, fn); /* This code section will delete all the files in the directory. */ if (strcmp(fn, &quot;*.*&quot;) == 0) { _dos_findfirst (&quot;*.*&quot;, _A_NORMAL, &c_file); do { remove (c_file.name); } while (_dos_findnext (&c_file) == 0); } else /* This section will delete only one file. */ if (remove (fn) == -1) printf (&quot;File not found\n&quot;); else printf (&quot;File successfully deleted\n&quot;); } Additional reference words: kbinf 1.00 1.50 5.10 6.00 6.00a 6.00ax 7.00 KBCategory: kbprg kbcode KBSubcategory: CRTIss
