File_Copy()
Syntax
File_Copy(pSourceName As String * 13, bSourcePartition As Byte, ByRef pSourcePath As Dword, pDestName As String * 13, bDestPartition As Byte, ByRef pDestPath As Dword), Byte
Parameters
pSourceName — file's name to be copied
bSourcePartition — partition number where the file resides
pSourcePath — source string buffer array — a string variable is required here, since ByRef passes its address automatically
pDestName — new destination file name
bDestPartition — partition number where the file will be copied to
pDestPath — destination string buffer array — a string variable is required here, since ByRef passes its address automatically
Return value — cErrOK = success
cErrNotFound = source file or a directory path missing
cErrExists = destination already exists
cErrInvalidPath = bad partition number
cErrRWError
Copies a file between any two partitions and/or directories
Copies a file between any two partitions and/or directories, chunk by chunk. pSourcePath/pDestPath are directory paths (e.g.
"photos/2024"), passed the same way as File_MkPath()/File_SetPath() - pass an empty string for root.
Every partition switch resets to root so both paths are re-walked before every file operation which adds overhead.
To speed up the copy process you can increase the copy buffer size by changing the "baCopyBufferSize" declaration in Fat.inc, but this will add more RAM usage, currently set to 64 bytes (Symbol baCopyBufferSize = 64)
Restores whichever partition was active before this call on exit.

Dim sTemp As String * 20 'Create string array variable Dim sTemp1 As String * 20 'Create string array variable File_ListPartitions() 'Detect partitions File_SetPartition(2) 'Set currently active partition 2 sTemp = "my/home" 'Place some path in this string variable sTemp1 = "is/here" 'Place some path in this string variable 'Copy "po.txt" from partition 4 sub folders my/home 'as "fo.txt" to partition 3 Sub folders is/here File_Copy("po.txt",4,sTemp,"fo.txt",3,sTemp1) |
