FreeCommander Forum

Hi All,

I would like to notify that has been a while with several performance issue with FreeCommander at least since the last five versions till this one: "FreeCommander XE 2023 Build 885 64-bit donor".

Not sure if and how send you a log to catch these problems but I'll let you what I noticed:

• Remote folders with a lot of AI and PDF files take age to unfreeze FC when in "icon view"; perhaps FC should have its own system to store thumbnails and update those only when a file has changed.
• Rename files often freezes the UI

For me the main causes are:

1. Thumbnail generation of AI/PDF/PS files.
2. The fact that I work 99% exclusively on image files over a local network (ActiveDirectory I guess).

Unfortunately this is happening too much frequently, usually I mitigate it keeping the files in list view, but sometimes I forgot to switch view, and sometimes I need to watch the thumbnail and that becomes a problem: one time out of three the UI gets frozen and I have to kill the process manually.

Thanks,

D.

Try the following:
- check the location of the freecommander.ini under Help->About
- close FreeCommander
- open freecommander.ini with the text editor (e.g. notepad)
- find the line with ThumbsPdfInternal= and change the value to 0: ThumbsPdfInternal=0
- save the change and close the file
- start FC and check your problem

Thanks, I will and I'll report the behavior!

HI Marek,

with that change it was even worst.

Let me explain a bit the situation maybe can help you to figure out a proper workaround: my PDFs are 99% Printing PDF with average of 100MB each, I have hundreds of them in many folders. These are complex PDF files (mainly Adobe Illustrator generated) and I can imply that are complex to read through especially when there are hundreds in each folder.

Unless you can introduce a method that stores thumbnails once, and these are updated only when the correspondent file changes, you may by default setup FC to not generated preview if AI/PDF files are bigger than 20MB; even though for me is very useful watching the preview cause sometime a product's names change by a single digit but they look totally different to each other, all these constant freeze are becoming a pain on the neck.

Thanks,

D.

Is there anywhere I can download such a large pdf file?

I found this: https://www.sampledocs.in/

First file in the list is 100MB PDF sample.

I can provide dummy heavy weight PDF, thanks...

Its no general problem to view this 100MB PDF with the FC integrated viewer but its slow.
Using the Total Commander SLister plugin which make use of SumatraPDF
this job is done with no delay at all.

I think this is not about the internal viewer but about the display of thumbnails.
I have added the possibility to use the Windows thumbnails cache for viewing thumbnails.

When will be available this change? Thanks!
