<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">With this feature, you can copy part or all of a ShrinkIt file archive to a new ProDOS volume in a single step. When combined with the "convert disk image to file archive" feature, it's possible to resize ProDOS disks, converting 140K floppies to 800K floppies or even 32MB hard drive images.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Open a file archive and highlight the files you want to convert. Items will be converted in the order that they appear, so if you want to leave the order undisturbed make sure you have them sorted in the original order (<A HREF="t50.htm">more information on this</A>). Select "Convert to disk archive..." from the Actions menu.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Choose the size of the disk to create from the set shown. Standard removable media and hard drive sizes are available. If you're not sure how much space the files require, click the "Compute" button. The size requirements will be determined by creating a temporary 32MB volume with the selected files and adjusting for system overhead. Any size options that won't work will be dimmed.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Filenames on ProDOS disks must start with a letter, be composed entirely of letters, numbers, and dots ('.'), and can be at most 15 characters long. Any invalid characters will be stripped, and long filenames will be truncated. CiderPress will try to preserve filename extensions (e.g. ".jpg"), and will make filenames that reduce to the same thing unique. For example, "my&&file" and "my__file" both convert to "myfile", so the first is stored as "myfile" and the second as "myfile1".</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">ProDOS stores filenames using upper case letters only. A modification added for the benefit of the GS/OS ProDOS FST allows mixed-case names with spaces in them, but the method used to store the case information can confuse older versions of ProDOS 8. The "Allow lower-case ProDOS names" option in <A HREF="t259.htm">Disk Image Preferences</A> lets you tell CiderPress whether to create lower-case names on ProDOS disks. If you're planning to use the disk with a pre-v1.8 version of ProDOS 8, you should not enable the feature, or your files may be inaccessible.</FONT></P>

If you are working with 32MB hard drive partitions, performance on systems with insufficient RAM may suffer.</FONT></P>
