How to copy a single file?
I have a problem with copying files one at a time. I'm trying to do a section where I read a string from a file and the use it to determine if a file exists in some directory. If it doesn't exists a file corresponding to the string will be copied to the target directory from a temp directory, if the file(in some form, <string>-*.jar) exists the user will be asked if (s)he wants to overwrite the old file with the new.

For now I'm just trying to copy all the files one at a time using CopyFiles, but I usually get an error or nothing happens.

Something like this:

FileOpen $1 "$INSTDIR\strings.txt" "r"

loop:
FileRead $1 $2
IfErrors done

CopyFiles /FILESONLY "$INSTDIR\somedir\$2*.jar" "$TARGETDIR"

IfErrors copyFailed
Goto loop

done:
MessageBox MB_OK "Done."
FileClose $1
Return

copyFailed:
MessageBox MB_OK "Copy operation failed."
FileClose $1
Return

IfFileExists checks if your file is already existing in $TARGETDIR.

for string operations, use TextFunc.nsh and WordFunc.nsh.

there's a forum thread somewhere, where the current versions are posted regularly.

"Delete/FileOpen/CopyFiles don't work" :cry:
Please change it "do not" or "doesn't"! :p

Thanks all. Figured it out on my own.
The problem were the new line characters. I got the imression from the help that those characters wouldn't be in the string, so that didn't come to mind until yesterday.
