code is still giving me this error when i already asked on here and had it troubleshooted. Please help i need this program to work. Where I can extract any file in the disk img for example ./extract_file disk1.img CONFIG.SYS #include #include #include #include #pragma pack(push, 1) typedef struct { int8_tjump_to_bootstrap[3]; int8_toem_id[8]; uint16_tbytes_per_sector; uint8_tsectors_per_cluster; uint16_treserved_sectors; uint8_tfat_copies; uint16_troot_dir_entries; uint16_ttotal_sectors; uint8_tmedia_descriptor_type; uint16_tsectors_per_fat; uint16_tsectors_per_track; uint16_theads; uint32_thidden_sectors; uint32_ttotal_sectors2; uint8_tdrive_index; uint8_t_stuff; uint8_tsignature; uint32_tid; int8_tlabel[11]; int8_ttype[8]; int8_t_more_stuff[448]; uint16_tsig; } boot_t; typedef struct { int8_tfilename[8]; int8_textension[3]; int8_tattributes; int8_t_reserved[10]; uint16_tupdate_time; uint16_tupdate_date; uint16_tstarting_cluster; uint32_tfile_size; } dir_entry_t; #pragma pack(pop) void readSector(FILE *disk, uint32_t sectorNumber, uint8_t *buffer, uint16_t bytesPerSector) { if (disk==NULL) { fprintf(stderr, "Invalid file pointer.\n"); return; } if (buffer==NULL) { fprintf(stderr, "Invalid buffer pointer.\n"); return; } if (fseek(disk, sectorNumber*bytesPerSector, SEEK_SET) !=0) { perror("Error seeking file"); return; } size_tbytesRead=fread(buffer, 1, bytesPerSector, disk); if (bytesRead!=bytesPerSector) { if (feof(disk)) { fprintf(stderr, "End of file reached unexpectedly.\n"); } else if (ferror(disk)) { perror("Error reading file"); } return; } } void readMBR(FILE *disk, boot_t *bootSector) { uint8_tbuffer[512]; readSector(disk, 0, buffer, 512); memcpy(bootSector, buffer, sizeof(boot_t)); } dir_entry_t* getRootDirEntries(FILE *disk, boot_t *bootSector) { uint16_trootDirSectors= ((bootSector->root_dir_entries*32) + (bootSector->bytes_per_sector-1)) /bootSector->bytes_per_sector; uint8_t*buffer= (uint8_t*)malloc(rootDirSectors*bootSector->bytes_per_sector); readSector(disk, bootSector->reserved_sectors+ (bootSector->fat_copies*bootSector->sectors_per_fat), buffer, rootDirSectors*bootSector->bytes_per_sector); return (dir_entry_t*)buffer; } dir_entry_t* findRootDirEntry(const char *filename, dir_entry_t *entries, uint16_t numEntries) { for (inti=0; ireserved_sectors+ (bootSector->fat_copies*bootSector->sectors_per_fat) + ((bootSector->root_dir_entries*32+bootSector->bytes_per_sector-1) /bootSector->bytes_per_sector); uint32_tfirstSectorOfCluster= ((clusterNumber-2) *bootSector->sectors_per_cluster) +firstDataSector; for (inti=0; isectors_per_cluster; i++) { readSector(disk, firstSectorOfCluster+i, buffer+ (i*bootSector->bytes_per_sector), bootSector->bytes_per_sector); } } void extractFile(FILE *disk, dir_entry_t *entry, boot_t *bootSector) { uint8_t*buffer= (uint8_t*)malloc(entry->file_size); uint32_tcluster=entry->starting_cluster; uint32_tbytesRead=0; while (bytesReadfile_size) { readCluster(disk, cluster, buffer+bytesRead, bootSector); bytesRead+=bootSector->bytes_per_sector*bootSector->sectors_per_cluster; cluster++; } FILE*output=fopen("output_file", "wb"); fwrite(buffer, 1, entry->file_size, output); fclose(output); free(buffer); } int main(int argc, char *argv[]) { if (argc!=3) { fprintf(stderr, "Usage: %s \n", argv[0]); return1; } constchar*diskImage=argv[1]; constchar*filename=argv[2]; FILE*disk=fopen(diskImage, "rb"); if (disk==NULL) { perror("Error opening disk image"); return1; } boot_tbootSector; readMBR(disk, &bootSector); dir_entry_t*entries=getRootDirEntries(disk, &bootSector); dir_entry_t*entry=findRootDirEntry(filename, entries, bootSector.root_dir_entries); if (entry) { extractFile(disk, entry, &bootSector); printf("File extracted successfully.\n"); } else { fprintf(stderr, "File not found in root directory.\n"); } free(entries); fclose(disk); return0; }
