# affcopy(1)

reorder and recompress AFF files

## NAME

**affcopy** - reorder and recompress AFF files

## SYNOPSIS

```
affcopy [options] file1 file
affcopy [options] file1 file2 file3 ... dir
affcopy [options] file1 file2 file3 ... dir1 dir2...
```

## DESCRIPTION

Copy one AFF *file* to another. Resulting *file* is re-ordered and possibly re-compressed.

This *file* is part of the AFFLIBv3, that provides AFF.

AFF is an open and extensible *file* format to store disk images and associated metadata. It is useful in several scenaries, as computer forensics investigations.

## OPTIONS

General *options*:

- **-d**

  Print debugging information as well.

- **-h**

  Help, print this message.

- **-L**

  Recompress pages (preen) with LZMA (smaller but slower).

- **-m**

  Just copy the missing segments.

- **-V**

  Print the program version and exit.

- **-v**

  Verbose: print each *file* as it is copied.

- **-vv**

  Very verbose: print each segment as it is copied.

- **-x**

  Don't verify hashes on reads.

- **-Xn**

  Recompress pages (preen) with zlib level n.

- **-y**

  Don't verify writes.

- **-z**

  ZAP (delete). Copy even if the destination exists.

Signature Options:

- **-k \<filename.key\>**

  Specify private key for signing.

- **-c \<filename.cer\>**

  Specify a X.509 certificate that matches the private key (by default, the *file* is assumed to be the same one provided with the **-k** option).

- **-n**

  Read notes to accompany the copy from standard in.

Encryption Options:

```
    Is possible specify passphrase encryption for filename.aff with:
    file://:passphrase@/filename.aff
```

## EXAMPLES

Copy *file1* to *file2*:

```
    $ affcopy file1 file
```

Copy all files to *dir*:

```
    $ affcopy file1 file2 file3 dir
```

Copy *file1* to *dir1*, *file2* to dir2 and *file3* to dir3:

```
    $ affcopy file1 file2 file3 dir1 dir2 dir3
```

Encrypt file.aff:

- **$ affcopy**

  file.aff   *file*://:mypassword@/*file*-encrypted.aff

Copy all files in current directory to S3 default bucket with X9 compression:

```
    $ affcopy -vy -X9 *.aff s3:///
```
