Catalogue File Card
Gives a list of information on all files in a Flash or EPROM card. The directories and file names will be given to show where the files originally came from.
Flashing Display whilst using Flash or EPROM card is normal
When you catalogue or save to a blank EPROM, the display will go blank for a few seconds while the EPROM is checked. This also happens with Flash cards when OZ is running on the same card. This happens only once; afterwards cataloging is without flickering.
Save to File Card
Copies files from the filing system to a Flash or EPROM card. The file or files to be saved can either be selected as already described, or specified after the prompt
When a file is being saved to EPROM or to a Flash card in Slot 1, the screen will blank intermittently (if OZ is running on the same card) until saving is completed, when the Cambridge Z88 will bleep.
Warning: the display may be blank for a long time when saving large files
When saving very large file, the Z88 may appear to be doing nothing. It isn't, it is just working as fast as it can so leave it alone. For example a 368K file can take up to 3 minutes to complete, so just wait.
Several files may be saved at the same time. See Select Extra File
UV EPROM fully erased?
From OZ 4.5 a check is made that the file area is fully erased when using this command for the first time. Users using previous versions should check that the EPROM is fully erased using ROMcombiner.
Fetch from File Card
Copies files from Flash or EPROM card back to the filing system. Gives the prompts
Source: specifies the name of the file in the EPROM.
Destination: gives the name it is to be saved as in the destination filing system. It is initially set to the same as the source name, but you can edit it if you want to save the file under a different name.
Makes a second copy of a file in RAM. Gives the prompt
allowing you to specify the file name to be copied, followed by the prompt
for the name of the copy.Multiple files (selected in the catalogue window) can be merged into a single file with the Copy command; they will be appended in the order in which they were selected. See Select Extra File
Allows the name of a file in RAM to be altered. Gives the prompts
For example, to change the name of a file from game.bas to 0ldversion you would specify
Note that you cannot use the Rename command to move a file from one directory or device to another. The new name must be a simple file name; devices and path names are not permitted.
Allows one or more files from RAM to be removed from the filing system. Gives the prompt
followed by the prompt
You will not be permitted to erase a file which is in use; for example, a directory containing other files, or an open BASIC file.
Several files may be erased at the same time. See Select Extra File
Select File Card
Selects the slot for the default File Card. This is selected using the number keys, 0-3 orJ to toggle each slot number.
Create File Card
If the Flash card is blank, this command formats the File Area for the first time. If this has already been done and there are some files already saved, this command will format the file area again after giving a warning.
Sets the current directory to the specified directory. Gives the prompt
displaying the current directory string (if any).
For example; to set the current directory to directory
If the directory has not been created, a
Sets the current RAM device. Gives a prompt such as
showing the current device, which can be edited to the required new device.
The Select Device command resets the current directory to the root directory.
The Select Device and Select Directory commands affect the device and directory for the activity from which the Filer was entered, if there is one. This allows different activities to use different devices and directories without the need for specifying them explicitly each time.
These commands are used for traversing a hierarchical directory structure. To select a directory move the highlight bar to the directory name in the Filer DIRECTORY window and press . To go back up to the parent directory press .
Executes a CLI file of commands specified after the prompt
See CLI files below.
Creates a directory within the current directory; the name is specified after the prompt
Copies a file tree from one directory to another. Arguments to the S o u r c e and D e s t i n a t i o n fields must be devices or directories. For example,
will make a duplicate copy of all files from RAM card 1 to RAM card 2.
The source area cannot be part of the destination area.
Sets up a match string restricting access to files in the current directory to those that match the string. For example, setting
Will catalogue only files with a
When this command is issued, the user is prompted for the file name.
Alternatively, to avoid making typing errors, the file may be marked beforehand
and then the command issued
The CRC-32 (checksum) value of the file is displayed. It is used by several applications on the Z88 (Eazylink2, FlashStore, ROMupdate) to ensure file integrity. CRC-32 is found in many desktop applications as well.
|The cursor keys are used to navigate around the file.|
|is used to toggle the cursor between the HEX display on the left and the ASCII display on the right.|
|Quits this View File function, but remains in the Filer.|
Make sure you useto leave this pop down otherwise an 'In use' error message will be shown when the file is deleted. The only way of clearing this error is with either a Soft or Hard Reset, risking losing files in RAM.
