onstants.NAMELEN - offset 0 char mode[8]; // TarConstants.MODELEN - offset 100 char uid[8]; // TarConstants.UIDLEN - offset 108 char gid[8]; // TarConstants.GIDLEN - offset 116 char size[12]; // TarConstants.SIZELEN - offset 124 char mtime[12]; // TarConstants.MODTIMELEN - offset 136 char chksum[8]; // TarConstants.CHKSUMLEN - offset 148 char linkflag[1]; // - offset 156 char linkname[100]; // TarConstants.NAMELEN - offset 157 The following fields are only present in new-style POSIX tar archives: char magic[6]; // TarConstants.MAGICLEN - offset 257 char version[2]; // TarConstants.VERSIONLEN - offset 263 char uname[32]; // TarConstants.UNAMELEN - offset 265 char gname[32]; // TarConstants.GNAMELEN - offset 297 char devmajor[8]; // TarConstants.DEVLEN - offset 329 char devminor[8]; // TarConstants.DEVLEN - offset 337 char prefix[155]; // TarConstants.PREFIXLEN - offset 345 // Used if "name" field is not long enough to hold the path char pad[12]; // NULs - offset 500 } header; All unused bytes are set to null. New-style GNU tar files are slightly different from the above. For values of size larger than 077777777777L (11 7s) or uid and gid larger than 07777777L (7 7s) the sign bit of the first byte is set, and the rest of the field is the binary representation of the number. See TarUtils.parseOctalOrBinary.
The C structure for a old GNU Tar Entry's header is:
```
 struct oldgnu_header { char unused_pad1[345]; // TarConstants.PAD1LEN_GNU       - offset 0 char atime[12];        // TarConstants.ATIMELEN_GNU      - offset 345 char ctime[12];        // TarConstants.CTIMELEN_GNU      - offset 357 char offset[12];       // TarConstants.OFFSETLEN_GNU     - offset 369 char longnames[4];     // TarConstants.LONGNAMESLEN_GNU  - offset 381 char unused_pad2;      // TarConstants.PAD2LEN_GNU       - offset 385 struct sparse sp[4];   // TarConstants.SPARSELEN_GNU     - offset 386 char isextended;       // TarConstants.ISEXTENDEDLEN_GNU - offset 482 char realsize[12];     // TarConstants.REALSIZELEN_GNU   - offset 483 char unused_pad[17];   // TarConstants.PAD3LEN_GNU       - offset 495 }; 
```
Whereas, "struct sparse" is:
```
 struct sparse { char offset[12];   // offset 0 char numbytes[12]; // offset 12 }; 
```
