File save

AndurielMarch 26, 2004 at 3:07 PM#

I would like to know how we can make to look if the files which we want to extract are already present in a file. And if yes, then it is copied and stuck in a file back up.

Thank you 🙂

Joost VerburgMarch 26, 2004 at 3:11 PM#

Use IfFileExists.

AndurielMarch 26, 2004 at 3:49 PM#

I'am sorry but I don't know any syntax... I'am a noob and I must learn with examples 🙂 lol. Can you say me just the syntax? Thanks you

P.S Is my English good 😁?

Joost VerburgMarch 26, 2004 at 4:07 PM#

You can find the syntax of this command in the users manual.

I found:

file_to_check_for jump_if_present [jump_otherwise]

and I read the explication but it don't better help me... I replace that: file_to_check_for jump_if_present by my file's name? but what is it [jump_otherwise] ?

edit: I found too:
[/SILENT] [/FILESONLY] filespec_on_destsys destination_path [size_of_files_in_kb]
and
path_to_create

I don't know where I must put it and what Replace...
Thank ou 🙂

IfFileExists "$INSTDIR\myfile.exe" 0 notexist



  ;Backup the file here



notexist:

AndurielMarch 27, 2004 at 11:42 AM#

For example:

IfFileExists "$INSTDIR\logo.bmp" 0 notexist

"$INSTDIR\SavesMdl\logo.bmp"

notexist:

I am not sure that "$INSTDIR\SavesMdl\logo.bmp" is good...

Joost VerburgMarch 27, 2004 at 12:56 PM#

That looks like a valid path.

AndurielMarch 27, 2004 at 3:58 PM#

Sorry but I don't understand... :/ Can you write me an example? That looks like a valid path and you don't know what I have to do?

BrummelchenMarch 27, 2004 at 4:08 PM#

>> "$INSTDIR\SavesMdl\logo.bmp"

this is only parameter, where is the function ???

Joost VerburgMarch 27, 2004 at 6:23 PM#

Use CopyFiles for the backup.

AndurielMarch 28, 2004 at 7:49 AM#

So:



IfFileExists "$INSTDIR\logo.bmp" 0 notexist

[/SILENT] [/FILESONLY] "logo.bmp" "$INSTDIR\SavesMdl\logo.bmp" [100]

notexist:

?

Joost VerburgMarch 28, 2004 at 8:10 AM#

No, you should use the CopyFiles command with the syntax as described in the manual, not copy the syntax description.

CopyFiles /SILENT "$INSTDIR\SavesMdl\logo.bmp" "$INSTDIR\SavesMdl\logo-backup.bmp"

AndurielMarch 28, 2004 at 9:36 AM#

Ok thx I begin to understand 🙂 But for what I replace that: filespec_on_destsys? I saw, you had twice the same thing and I don't understand that. And what is /FILEONLY then?
My new code:



SetOutPath "$INSTDIR"

  SetOverwrite on

     File "logo.bmp"

     IfFileExists "$INSTDIR\logo.bmp" 0 notexist

CreateDirectory "$INSTDIR\SavesMdl\"

CopyFiles /SILENT "$INSTDIR\SavesMdl\logo.bmp" "$INSTDIR\SavesMdl\logo-backup.bmp"

notexist:

But even if the file exists not it created a save, moreover which does not work. It is written during the install "Copy failed "... What is the problem?
thx

Joost VerburgMarch 28, 2004 at 11:27 AM#

filespec_on_destsys is the source for the file copy. /FILEONLY is a flag that is useful if you want to copy a whole folder but not the folders inside that folder.

You didn't say that it was the backup directory for the file. Try:

SetOutPath "$INSTDIR"



IfFileExists "$INSTDIR\logo.bmp" 0 notexist



  CreateDirectory "$INSTDIR\SavesMdl"

  CopyFiles /SILENT "$INSTDIR\logo.bmp" "$INSTDIR\SavesMdl\logo.bmp"



notexist:



File "logo.bmp"

AndurielMarch 28, 2004 at 1:59 PM#

Thank you very much that works! But I would like to know if it is possible actually an IfFileExists generally, not file by file, simply " if A file exists to copy IT... "
Thank you very much 😁

Joost VerburgMarch 28, 2004 at 2:13 PM#

If you want to do the same thing for many files, create a macro or function.

AndurielMarch 28, 2004 at 2:34 PM#

Sorry but I don't see what do you want to say...

Joost VerburgMarch 28, 2004 at 3:44 PM#

Please read the manual for information about function and macros. This forum is not a script writing service.

AndurielMarch 28, 2004 at 3:50 PM#

yes lol I know but I think a look not on the good page... I read here: http://nsis.sourceforge.net/Docs/
That's good?

Joost VerburgMarch 28, 2004 at 4:16 PM#edited March 28, 2004 at 4:36 PM

That is indeed the users manual. A macro can be used to insert certain commands multiple times, with different parameters.

Example:

!macro FILEWITHBACKUP FILE



  IfFileExists "$INSTDIR\${FILE}" 0 notexist



    CreateDirectory "$INSTDIR\SavesMdl"

    CopyFiles /SILENT "$INSTDIR\${FILE}" "$INSTDIR\SavesMdl\${FILE}"



  notexist:



  File "${FILE}"



!macroend

!insertmacro FILEWITHBACKUP "logo.bmp"

Thx I tested that but I have a very big problem, I need three different roads for the same file: the problem during the compilation:

IfFileExists: $"INSTDIR\maps\cs_deagle5.bsp? 0: CopyFiles notexist: silent ) $"INSTDIR\maps\cs_deagle5.bsp - > " $INSTDIR\CS-Combo\save_map\maps\cs_deagle5.bsp ", size=0KB File: "maps\cs_deagle5.bsp" - > no File found.

Here it looks if the file exists, that it is good.
Here is where it going to copy it, but it resumes the same road, what distorts everything!
Here it is the file which is not found because it is not situated! I simple used !insertmacro FILEWITHBACKUP " map\cs_deagle.bsp...

Thx
