AmigaOS 4.0 - About OS4 - Commands

Purpose: To extract data from disk archives.
XADUNDISK is the master shell tool to extract data from disk archives.

FROM specifies the disk archive that should be processed.

The TO option specifies the destination. This maybe an device name like RAD: or any file name. The TO is required unless the LIST option is specified. When extracting to a file, this is a floppy image file (often called ADF), which can be used with all ADF dealing tools.

The LOWCYL and HIGHCYL options specify the lowest and highest cylinder that should be de-archived. Note that some clients do not support cylinder based de-archiving and thus ignore these options.

The ENTRY option specifies the entry, which should be dearchived. Normal disk archives only store one entry, so there is no need for this option, but for multi-disk-archivers you can specify the entry that you require. This is a decimal number where the first entry has number 1.

The PASSWORD option can be used to supply a password for unarchiving of encrypted archives.

The SAVETEXTS=<filename> option enles you to specify a filename which can be used to save information texts. The name gets an additional point and the text number, e.g. "SAVETEXTS=text" produces files text.1, text.2, ...

The NE or NOEXTERN prohibits the use of external clients for recognition purposes.

The INFO or LIST option prints information about the archive but does not do any unarchiving.

The SHOWTEXTS option tells XADUNDISK to display information texts, if there are any of them in the archive.

The OW or OVERWRITE option forces XADUNDISK to overwrite an already existing destination file.

The IG or IGNOREGEOMETRY option forces XADUNDISK to ignore wrong drive geometry when unarchiving to an device.

The USL or USESECTORLABELS option specifies that you want to store SectorLabels onto disk (no effect for output files). Not all archivers support them and not all destination device types support this storage. Most of the time you will not need this switch, as the labels seldom contain useful information.

If the destination disk is not formatted, use the FORMAT option to do this together with writing.

The DIMG or DISKIMAGE option is used when you want to write a disk image to floppy disk. The program also asks you, if you want to handle a file as image, if the data type is not detected without the DIMG keyword.

The NAI or NOASKINSERT specifies that you do not want to be asked to insert disk.

Example 1:

3.OS4:> XADUNDISK archive.dms RAD: unarchives the dms file to RAD:.

Example 2:

3.OS4:> XADUNDISK archive.dms LIST displays information about the archive.dms file.
