.SH "NAME"
cc1541 \- A tool for creating Commodore 1541 Floppy disk images in D64, D71 or D81 format with custom sector interleaving etc\&. Also supports extended tracks 35\-40 using either SPEED DOS or DOLPHIN DOS BAM\-formatting\&.

.RE
.PP
\fB\-i id\fR
.RS 4
Disk ID, default=\fI00 2a\fR\&.
.RE
.PP
\fB\-H message\fR
.RS 4
Hidden BAM message\&. Only for D64 (up to 85 chars) or SPEED DOS (up to 20 chars)\&.
.RE
.PP
\fB\-w localname\fR
.RS 4
Write local file to disk, if filename is not set then the local name is used\&. After file written, the filename is unset\&.
.RE
.PP
\fB\-W localname\fR
.RS 4
Like \-w, but encode file in Transwarp format\&.
.RE
.PP
\fB\-K key\fR
.RS 4
Set an encryption key for Transwarp files, a string of up to 29 characters\&.
.RE
.PP
\fB\-f filename\fR
.RS 4
Use filename as name when writing next file, use prefix
\fI#\fR
to include arbitrary PETSCII characters (e\&.g\&. \-f "START#a0,8,1")\&.
.RE
.PP
\fB\-o\fR
.RS 4
Do not overwrite if file with same name exists already\&.
.RE
.PP
\fB\-V\fR
.RS 4
Do not modify image unless it is in valid CBM DOS format\&.
.RE
.PP
\fB\-T filetype\fR
.RS 4
Filetype for next file, allowed parameters are PRG, SEQ, USR, REL and DEL, or a decimal number between 0 and 255\&. Default is PRG\&.
.RE
.PP
\fB\-P\fR
.RS 4
Set write protect flag for next file\&.
.RE
.PP
\fB\-O\fR
.RS 4
Set open flag for next file\&.
.RE
.PP
\fB\-N\fR
.RS 4
Force creation of a new directory entry, even if a file with the same name exists already\&.
.RE
.PP
\fB\-l filename\fR
.RS 4
Write loop file (an additional dir entry) to existing file to disk, set filename with \-f\&.
.RE
.PP
\fB\-L\fR
.RS 4
Add dir entry without writing file (track and sector will be 0), requires a filename given with \-f\&.
.RE
.PP
\fB\-B numblocks\fR
.RS 4
Write the given value as file size in blocks to the directory for the next file\&.
.RE
.PP
\fB\-M numchars\fR
.RS 4
Hash computation maximum filename length, this must match loader option FILENAME_MAXLENGTH in Krill\(cqs loader\&. Default is 16\&.
.RE
.PP
\fB\-m\fR
.RS 4
Ignore filename hash collisions, without this switch a collision results in an error\&.
.RE
.PP
\fB\-d track\fR
.RS 4
Maintain a shadow directory (copy of the actual directory without a valid BAM)\&.
.RE
.PP
\fB\-t\fR
.RS 4
Use directory track to also store files (makes \-x useless) (default no)\&.

.RS 4
Don\(cqt split files over directory track hole (default split files)\&.
.RE
.PP
\fB\-F\fR
.RS 4
Next file first sector on a new track (default=0)\&. Any negative value assumes aligned tracks and uses current sector + interleave \- value\&. After each file, the value falls back to the default\&. Not applicable for D81\&.
.RE
.PP
\fB\-S value\fR
.RS 4
Default sector interleave, default=10\&. Not applicable for D81\&.
.RE
.PP
